Hi,
Haynes R J and Williams P H have extensively worked on sheep and
cattle patch areas of pasture in Australia and New Zealand. Although
the following articles are mainly on N, I guess they might be
useful particularly to give some ideas regarding your sampling method.
Haynes R J and Williams P H 1992 J Soil Sci 43:323-334.
Haynes R J and Williams P H 1993 Adv Agron 49:119-199.
Williams P H and Haynes R J 1992 Plant & Soil 145:167-175.
Williams P H and Haynes R J 1993 J Agric Sci Camb\ 121:83-89.
Williams P H and Haynes R J 1994 Plant & Soil 162: 49-59.
The last one is mostly recommended.

Much work has also been done on P cycling in New Zealand steepland
pasture and also some work on S (Search for; A Gillingham, J Rowarth, M Hedley)
New Zealand work will generally refer to dairy production on rolling
country, or mixed stock grazing on very steep country. (we do not have
any feed lot production).
I am looking at K tranfer patterns around steep land paddocks, and have
found the use of detailed linear sampling patterns (eg one sample every 10m,in
a line that covers changes from camp zones to infrequently grazed zones-
samples are analysed individually) to yield the most infomation. I have
been using a lot of multivariate analysis techniques to look at the patterns
in the results. P, however, should be much more "stable" than K, and the
deposition pattern across the paddock will be directly related the faeces
deposition pattern (J Rowarth, PhD thesis, Massey University- can't remenber the
date sorry- about 1988)
Hope this helps :-)

Date: Sat, 1 Mar 1997 14:25:30 -0600
From: Michael Russelle <russelle@SOILS.UMN.EDU>
Subject: Re: Effect of Cattle ... on Soil P
A few contacts:
Cameron J.P. Gourley (gourleyc@dri.agvic.gov.au) is in charge of a large,
multi-investigator study in Victoria, Australia, on the interaction of dairy
cow stocking rate and P fertilization, in which P cycling is being measured.
David Correll has ongoing research in the northeastern USA on how pastures
influence nutrient losses and microorganism impacts on surface waters, and
has a recently published summary of work in 'Nutrient Cycling in Forage
Systems', R.E. Joost and C.A. Roberts (ed.), 1996. In the same volume, both
Bruce Matthews (Hawaii) et al., and Paul Peterson and Jim Gerrish (Missouri)
have chapters on nutrient distribution in pastures under various conditions.
You likely have heard about Andrew Sharpley's (ans3@psu.edu) work on P
dynamics. He is now at the USDA-ARS Pasture Laboratory in University Park, PA.
Jay Dorsey (jdorsey@soils.umn.edu) is involved in an on-farm investigation
of how management intensive grazing affects indexes of sustainability, among
which are soil nutrient status, bird populations, stream insect diversity,
etc.
A nice review article was written by Haynes and Williams (Advances in Agron.
49). There are several papers on excreta distribution (Peterson et al.,
Agron. J. 48:440 and 444; Richards and Wolton, J. Brit. Grassland Soc.
31:89; West et al., 1989, Soil Sci. Soc. Am J. 53:784).
Afzal and Adams (Soil Sci. Soc. Am. J. 56:1160) found that inorganic N
concentrations were as different between samples taken 10 cm apart as
samples taken at larger distances. Conclusion: You can't take enough
samples to characterize 50-acre pastures. Take John Sloan's advice and
concentrate on small areas for detailed sampling. If possible, measure
runoff from large areas, and try to predict those P losses from fine-scale
measurements.
Best of luck in your sampling.

Subject: Simple flux experiments
Hi all,
I was wondering if anyone could point me towards a simple, single session
(c. 2-3 hour) practical class which illustrates to 1st-year agriculture
students the relative importance(s) of diffusion and mass flow (and maybe
convection and/or capillarity as well!) for elemental fluxes in "the
environment".
"The Environment" could be plants, soils, aquatic systems, whatever, as
long as a first-year university student could complete and understand the
work in one session.
To avoid excess bandwidth, email to me direct and I'll summarize useful
tips to the group.
thanks for your collective help,

From: "Richard E. Woodward" <rwoodward@MINDSPRING.COM>
Subject: Microbe population measurement
Greetings! from Dick Woodward with Sierra Evironmental Services, Inc.,
Houston, TX. I am
microbiologist specializing in industrial microbiology applications. I am
interested in participating in this
list because many of my projects involve bioremediation of soils. In
addition to the usual hydrocarbon
remedial actions, recent clean ups have focused on a mixed glycol spill and
a nonylphenol (estorgen
disrupter) spill.
I routinely conduct treatablity studies to identify soil factors that are
limiting microbial growth then design a treatment system for field
implementation. I am particularly interested in how people monitor changes in
soil microbial populations and would be interested in starting a thread on
this topic.
I am currently using an instrument "borrowed" from the metal working
industry, to provide real-time
measurement of soil microbe populations. For the interest of the group:
HMB IV REPLACES PLATE COUNTS
The portable, hand-held HMB IV measures the population of aerobic
microorganisms in soils in 30
minutes. The battery operated unit provides near real-time measurements of
microbe population densities
for effective process control of bioremediation in the laboratory
(treatability studies) and in the field.
The data can define population trends for process control, verify the effect
of nutrients and adjuvants, and
evaluate the toxicity of candidate treatment materials. The assay measures
only viable, vegetative
biomass, so spores and resting structures that distort the traditional MPN/
plate count technique are
excluded. Because the instrument can test water, mixed liquor, sludge and
soils, the microorganism
population is measured in its own medium.
The HMB IV was recently featured in Water World, Water Technology News and
Environmental
Solutions Product Guide. Case studies featuring various applications have
been presented at ASM, ACS
and WEF conferences. If you are interested in near real-time data on
microbial population dynamics in
soils, send me your snail mail address. I'd be pleased to share my
experiences with the HMB IV.
Best regards,

FIRST CALL FOR VOTES (of 2)
unmoderated group sci.environment.waste
Newsgroups line:
sci.environment.waste Impact of Wastes and Waste Management Methods.
Votes must be received by 23:59:59 UTC, 26 Mar 1997.
This vote is being conducted by a neutral third party. Questions
about the proposed group should be directed to the proponent.
Proponent: Wolfgang Bujatti <sea-life@pacific-ocean.com>
Mentor: Jonathan Grobe <grobe@netins.net>
Votetaker: Jani Patokallio <jpatokal@alpha.hut.fi>
RATIONALE: sci.environment.waste
Keywords: waste management, hazardous waste, garbage, refuse,
industrial waste, municipal solid waste, domestic refuse, source
reduction,
collecting and fractioning of wastes, waste processing, reuse,
recycling,
incineration, waste treatment, conditioning to inert them, waste
disposal,
composting, hazard potential for subsequent generations, greenhouse
gases
The increasing quantity and the hazards of wastes evolved to a
very serious environmental problem. They can impair the general well-
being of man, animals, vegetation, their basis of existence or their
natural environment.
Waste-related discussions are currently taking place on environmental
newsgroups - particularly on sci.environment - but as this topic needs
an integrated approch by environmentalists, biologists, ecologists,
chemists, technicians and lawyers the Usenet community would be better
served by a more specific forum. Moreover it would ease the traffic at
sci.environment (about 30 postings a day).
This newsgroup is proposed to provide a forum for scientific
discussion on the one hand by people who are interested in the
effects which their wastes can take on our natural environment
(soil, water, air and the seas) and on the other hand by
people involved in collecting, fractioning, processing, treating,
recycling
or dumping wastes or other waste management methods.
This group is proposed as unmoderated group. A moderation should be the
last precaution against off-topic posts, spam, or repetitive flaming
(attacks). As this newsgroup has the aim to bring together very
differnent
groups of people it wouldn't be easy for a moderator to filter the
postings
to serve all. Sci.environment is an unmoderated group too.
This group is not being created as sci.bio.ecology.waste,
sci.engr.environment.waste or misc.legal.waste as it is intended
to maintain a scientifically and factually based focus of all
waste-related
topics rather than a primarily opinion based focus nor an only
specific biological, technical or legal talk.
I've chosen the label waste instead of a more specific description
(such as recycling or dumping) since this is the usual description for
departements of administrations, non governmental organisations and
enterprises.
CHARTER: sci.environment.waste
An unmoderated newsgroup which would provide a world wide forum for a
serious discussion by people who try to reduce wastes, which are
involved
with collecting, fractioning, processing, treating, recycling or dumping
wastes or with other waste management methods or people which treat
them,
so that they can reused for a different purpose, as well as by people,
who are cronfronted with the dangers of wastes in everyday life.
To assist governments, NGOs, environmentalists and scientists in the
acquisition of scientific and legal waste-related information as well as
an
informative arena on the many different world wide techniques of
conditioning, recycling and reusing wastes.
Specific topics may include but are not limited to:
+ the many different types of wastes and their effection on the
ecosystems in the soil, the rivers, the atmosphere and the seas and
oceans
+ industrial and municipal solid waste (domestic refuse)
+ dumping (nowadays or in the past) of toxic wastes in landfill sites
+ sealing and watertighten of landfill sites and underground dumping
sites
+ different world-wide skills and techniques of waste reduction in the
production-process, of processing, treating, recycling and reusing
wastes
and other waste management methods
+ environmental impact of waste treating plants and landfill sites
+ pros and cons of waste incineration and the rank of its spent air
+ waste-to-energy
+ specific problems of transport of hazardous wastes on land, air and
sea
+ pacticable collection systems
+ wastewater and sludges use, composting
+ reuse of tyres, waste-paper, packings, etc.
+ hazards of waste batteries, neon tubes, refrigerator-liquid,
synthetics, etc.
+ greenhouse gases
The following types of posts are strictly PROHIBITED in this newsgroup:
* Material and advertisments unrelated to conditioning, recycling, and
impact of wastes (off-topic)
* Spam (defined as articles posted to more than 5 newsgroups)
* Make-money-fast or other chain or fraudulent schemes
* Forged posts (anonymous posts are allowed)
* Personal insults or repetitive flaming (attacks)
The use of e-mail addresses from articles posted to this group for the
purpose of sending junk (mass unsolicited) e-mail or for compiling a
list so that others may do so is specifically PROHIBITED.
Binaries are only allowed by adding format or extension in the subject
line. On-topic advertising and employment (help and/or position wanted)
noticesis are limited to once per week. Please send such post only on
fridays.
Discussions about saving the nature without context to wastes should
better
take place on sci.environment or sci.bio.conservation, and the talk
about
energy-production (with the only exception of waste-to-energy
discussion)
and production techniques (with the only exception of waste reduction in
the
production-process) should better take place on sci.energy or on the
sci.engr hierarchy.
The general "netiquette" FAQs posted in news.announce.newusers and
news.answers apply to the proposed group. Participants are encouraged to
use descriptive Subjects (e.g., "Burning PCBs" rather than just "Help"
or
"Question").
In the absence of moderation, prohibitions can, of course, only be
enforced by the collective will of the group and/or by after-the-fact
complaints to the offender's service provider.
END CHARTER.
HOW TO VOTE:
Follow these instructions *exactly*! Votes are counted by computer.
You should send E-MAIL (posts to a newsgroup are invalid) to:
voting@hut.fi
Just replying to this message won't work.
Check the address before you mail your vote. Your mail message
should contain one and only one of the following vote statements:
I vote YES on sci.environment.waste
I vote NO on sci.environment.waste
Voter name:
If your mail software does not indicate your real name (for example, AOL
and
Delphi do not), include _exactly_ the statement above on a _separate_
line
and add your name after the colon. Having your name in your signature
line
is NOT enough! Do NOT join the lines together or remove the words
"Voter name"!
You may also vote ABSTAIN (which does exactly that) or CANCEL (which
removes any earlier votes). ABSTAIN does not affect the final vote
count
in any way but is listed, whereas CANCEL is not.
IMPORTANT VOTING PROCEDURE NOTES:
Standard Guidelines for voting apply. One person, one vote. Votes
must be mailed directly from the voter to the votetaker. Anonymous,
forwarded or proxy votes are not valid. Votes mailed by WWW/HTML/CGI
forms are considered to be anonymous votes.
Vote counting is automated. Failure to follow these directions may
mean that your vote does not get counted. If you do not receive an
acknowledgment of your vote within three days contact the votetaker
about the problem. It's your responsibility to make sure your vote
is registered correctly. Duplicate votes are resolved in favor of
the most recent valid vote. Addresses and votes of all voters will
be published in the final voting results post.
The purpose of a Usenet vote is to determine the genuine interest of
persons who would read a proposed newsgroup. Soliciting votes from
disinterested parties defeats this purpose. Please do not distribute
this CFV. If you must, direct people to the official CFV as posted
to news.announce.newgroups. Distributing pre-marked or otherwise
edited copies of this CFV is generally considered to be vote fraud.
When in doubt, ask the votetaker.

Bob:
We are doing some soil survey work with the HMB IV to locate petroleum
reservoirs by identifying soils with elevated microbe populations. We have
found a very strong positive correlation with other data (presence of
hydrocarbon degrading heterotrophs, seismic, satellite and drilling) and
elevated soil microbes over virgin (pressurized) deposits. The correlation
weakens after the reservoir has been tapped and depressurized over time.
Soil samples for the analysis were collected from the surface.
I routinely use the HMB IV to monitor soil bioremeidation in transects
across land treatment units. The HMB IV identifies areas with lower
activity so I can do additional sleuthing and take corrective action.
Frequently, the problem is ventilation (oxygen starvation due to soil
saturation), however at one site low pH apparently increased the
availability of some divalent cations (Cu, Mn and Zn) that supressed
microbial growth. Liming corrrected the problem.

RESEARCH ASSISTANT/ RESEARCH OFFICER
(Australian Research Council Funded Project)
MODELLING TRANSPORT OF CONTAMINANTS IN SOIL
Australia produces one of the highest volume of agricultural, industrial
and municipal wastes per capita in the world. Recent experiments suggest
that industrial & farm chemicals (such as fertilisers) and pesticides may
reach groundwater in much shorter times than current models predict. These
findings indicate we may be significantly under-estimating the risk of
groundwater contamination. A new and innovative experimental program funded
under a large ARC grant has recently commenced with the purpose of studying
heterogeneous solute transport in soils. The data will be mathematically
modelled for the purposes of understanding the key physical mechanisms
controlling transport and developing predictive tools for practical
applications.
A full-time Research Assistant/ Research Fellow position is available for
initially one year. The Research Assistant/ Research Fellow will assist in
the development of mathematical models and writing computer programs of
contaminant transport.
Essential Minimum Qualifications: An undergraduate Science degree,
specialising in Applied Mathematics or Engineering. A good working
knowledge of scientific programming in at least one of the following
languages: Fortran, Visual Basic, Pascal, C, and/or Mathematica.
Desirable Qualifications: Honours and/or postgraduate degree, mathematical
modelling of solute transport, computer visualisation techniques.
Salary: Commensurate with qualifications and experience: Research
Assistant: $26,205 - $30,340. Research Officer: $29,117 - $36,793.

pedogenesis; that aspect of pedology which views the growth of the soil over
time. For my one "Burning" topic I would like to invite the Soils-List

chemical (not radiometric) means for determining the age of organic carbon
(both charcoal and humus) within the soil context. The web site contains

Subject: Introduction (restoration/native plants in N. California)
I've been reading the list for several years; I'm working on propagating
native grasses from the 5000' elevation Ca. Coast Range, replanting sites
that have lost about a foot of topsoil in the past century (so the Nat'l.
Forest hydrologist with long experience up there tells me). I've realized
we're trying to propagate soil, basically -- starting from the half inch
or so of A-horizon remaining, some deeper pockets, and a lot of square
meters of fine gravel surface with very fine black silt below the top,
and isolated bunchgrasses standing on pedestals their roots are holding.
I've gotten soil microbiology samples done at OSU Corvallis for baseline,
put about 600 plants in, and have 12,000 more in a seed farm planting for
a seed increase (from a pound of hand-collected seed last year).
I'm very curious to know if anyone's worked on inoculating soil into
gravel/sand/mulch piles, trying to propagate the micro-biota that are
currently on the site. And whether there's much chance what's living
in the remaining soil will be at all close to what supported the original
soils there.
We're not expecting to "restore nature" -- just to keep from losing that last
half inch, hold off the Medusahead grass and other fire-prone invasives,
and get baseline info so over time, whatever does establish there can be
tracked and perhaps helped along. I figure it's a 200-year project.

Hank,
I was just wondering what microbial work was done - microbial biomass...?
I'm a graduate student at Texas A&M. My research is focused on
characterizing soil microbial changes in the Blackland Prairies of Texas
during succession or restoration. I don't know if I can be of any help -
but I'm interested.

Reply to SWRI and everybody,
I am a structural engineer in private practice, but I am also a
geologist. I have also published in the American Society of Civil
Engineers Journal of Geotechnical Engineering. My paper is about a new
theory for the origin of gilgai landforms. It seems that this topic has
been studied by researchers in every field related with soils. I think it
maybe prudent, to remind the agricultural folks that geotechnical
engineers do a great deal of research on moisture movement in soils.
Particularly in the area of unsaturated soils. For those interested in
gilgai or expansive soils I invite them to visit my web site at:
http://www.geocities.com/CapeCanaveral/9527/
In the next few weeks much more information will be added. I am working
on a bibliography on moisture movement in soils to add to this web site.
If you know of important studies, please contact me at the following

information. This software is crop specific and uses soil and/or plant tissue
test results to specify nutrient requirements in #/acre or some-such.

Dear SOILS-L
I'm interested in obtaining a copy and/or demo of fertiliser
recommendation software similar to that mentioned by
PEATCONS@AOL.COM recently Does anyone in the
list have an address for UC Davis Ag Research Dept.
or adresses for software (good freeware/shareware
and commercial software) that they have found useful
and reliable ?
I'm interested in the relevance of fertiliser recommendation
software to New Zealand so I'd also need information
about the analytical methods used to assess soil and plant
nutrient status. The methods may differ from those
currently used in New Zealand.
Thanks in advance

Subject: precision farming of forages
A few weeks ago, I asked people on the soils-l and forage-mg lists whether
they had any information on the use of precision agriculture techniques
relating to nutrient application on perennial forages. This is a summary of
the responses I received. I cannot vouch for the accuracy of this
information and no recommendation is implied in this listing; it is only as
complete as those who took time to reply -- my thanks to each of you who did:
Of course, some farmers have been practicing site specific farming of
forages for years. As Dan Wiersma (dwiersma@facstaff.wisc.edu) pointed out,
farmers in Wisconsin wanting legume hay will plant red clover in poorly
drained areas and alfalfa elsewhere. But more intensive site specific
management of nutrients on perennial forages does not appear to be widely
practiced at the present. According to several respondents, there is little
being done using this technology on forages in the Canadian Prairies, New
Zealand, California, Wisconsin, Minnesota, western New York state, Oklahoma,
Kansas, or Nebraska.
A few exceptions and interesting ideas follow:
1) Use of site specific application of lime is being tested in Wisconsin,
according to Dan Undersander (djunders@facstaff.wisc.edu).
2) Dan Wiersma reminded me that the planned regional dairy research center
in Marshfield, Wisconsin, will likely be farmed using precision agriculture
techniques. Land characteristics (field boundaries, soil characteristics,
elevation, etc.) will be built into a GIS database for future use.
3) In New Zealand, Jim Crush (crushj@agresearch.cri.nz) and colleagues are
planning to apply differential fertilizer P rates, depending on pasture
plant species presence. It evidently requires 3x more P to keep white clover
in a clover/perennial ryegrass mixture than for maximum yield of either in
monocultures under their conditions. How variable rates will affect plant
populations over time is unknown.
4) Chuck West (cpwest@comp.uark.edu) reported that Arkansas researchers and
extension personnel are promoting precision application of livestock waste
to avoid areas of high runoff potential. This has been based more on
landscape features than soil test results to date. Location and management
of rotational grazing is also being done in consideration of site specific
characteristics.
5) According to Dan Putnam (dhputnam@ucdavis.edu), researchers in
California have discussed the possibility of using site specific farming
with alfalfa, but do think it will pay on their relatively uniform soils,
considering the relatively low cost of P and K fertilizer.
6) Northwest Precision Ag (Blackfoot, Idaho, 208-785-5758) has just begun
grid sampling alfalfa fields for macro and micronutrients and will begin
detailed yield monitoring this year. They feel that the potential for
profitability of site specific farming is likely higher with perennial crops
that with annuals.
One requirement of site specific farming is the need to monitor yields over
the field to determine response to the variable input. Machinery for
forages has been lacking, but some equipment has been developed recently:
1) Leonard Bashford (bsen052@unlvm.unl.edu), Univ. of Nebraska, has worked
with a MS student to develop a baler with a yield monitor and GPS. They
will present a paper on the work this summer at the Am. Soc. Agric.
Engineers meeting in Minneapolis, MN.
2) Ag Tech Inc. and Technological Solutions International (tsi@initco.net)
have developed a yield monitor for use in windrowers, and has equipment and
software for site specific application of fertilizers and chemicals. TSI
does not recommend grid sampling, but rather take many fewer samples and
concentrate on sampling different landscape position, soil drainage, and
other characteristics that will likely impact yield.
3) Kevin Shinners (kjshinne@facstaff.wisc.edu) and Ron Schuler
(rschuler@facstaff.wisc.edu) have developed a forage harvester with yield
sensors that will be field tested this year.
4) I have heard that New Holland has developed or is developing forage and
manure application equipment to use with GPS, but found no information on
their web page about it.
That summarizes what I heard about in the past few weeks. Thanks, again,
for your responses. If you know of any other use of precision farming
approaches for fertilizer, livestock manure, or waste disposal on perennial
forages, please contact me. Thank you.

SECOND AND FINAL CALL FOR VOTES
unmoderated group sci.environment.waste
Newsgroups line:
sci.environment.waste Impact of Wastes and Waste Management Methods.
Votes must be received by 23:59:59 UTC, 26 Mar 1997.
This vote is being conducted by a neutral third party. Questions
about the proposed group should be directed to the proponent.
Proponent: Wolfgang Bujatti <sea-life@pacific-ocean.com>
Mentor: Jonathan Grobe <grobe@netins.net>
Votetaker: Jani Patokallio <jpatokal@alpha.hut.fi>
RATIONALE: sci.environment.waste
Keywords: waste management, hazardous waste, garbage, refuse,
industrial waste, municipal solid waste, domestic refuse, source
reduction,
collecting and fractioning of wastes, waste processing, reuse,
recycling,
incineration, waste treatment, conditioning to inert them, waste
disposal,
composting, hazard potential for subsequent generations, greenhouse
gases
The increasing quantity and the hazards of wastes evolved to a
very serious environmental problem. They can impair the general well-
being of man, animals, vegetation, their basis of existence or their
natural environment.
Waste-related discussions are currently taking place on environmental
newsgroups - particularly on sci.environment - but as this topic needs
an integrated approch by environmentalists, biologists, ecologists,
chemists, technicians and lawyers the Usenet community would be better
served by a more specific forum. Moreover it would ease the traffic at
sci.environment (about 30 postings a day).
This newsgroup is proposed to provide a forum for scientific
discussion on the one hand by people who are interested in the
effects which their wastes can take on our natural environment
(soil, water, air and the seas) and on the other hand by
people involved in collecting, fractioning, processing, treating,
recycling
or dumping wastes or other waste management methods.
This group is proposed as unmoderated group. A moderation should be the
last precaution against off-topic posts, spam, or repetitive flaming
(attacks). As this newsgroup has the aim to bring together very
differnent
groups of people it wouldn't be easy for a moderator to filter the
postings
to serve all. Sci.environment is an unmoderated group too.
This group is not being created as sci.bio.ecology.waste,
sci.engr.environment.waste or misc.legal.waste as it is intended
to maintain a scientifically and factually based focus of all
waste-related
topics rather than a primarily opinion based focus nor an only
specific biological, technical or legal talk.
I've chosen the label waste instead of a more specific description
(such as recycling or dumping) since this is the usual description for
departements of administrations, non governmental organisations and
enterprises.
CHARTER: sci.environment.waste
An unmoderated newsgroup which would provide a world wide forum for a
serious discussion by people who try to reduce wastes, which are
involved
with collecting, fractioning, processing, treating, recycling or dumping
wastes or with other waste management methods or people which treat
them,
so that they can reused for a different purpose, as well as by people,
who are cronfronted with the dangers of wastes in everyday life.
To assist governments, NGOs, environmentalists and scientists in the
acquisition of scientific and legal waste-related information as well as
an
informative arena on the many different world wide techniques of
conditioning, recycling and reusing wastes.
Specific topics may include but are not limited to:
+ the many different types of wastes and their effection on the
ecosystems in the soil, the rivers, the atmosphere and the seas and
oceans
+ industrial and municipal solid waste (domestic refuse)
+ dumping (nowadays or in the past) of toxic wastes in landfill sites
+ sealing and watertighten of landfill sites and underground dumping
sites
+ different world-wide skills and techniques of waste reduction in the
production-process, of processing, treating, recycling and reusing
wastes
and other waste management methods
+ environmental impact of waste treating plants and landfill sites
+ pros and cons of waste incineration and the rank of its spent air
+ waste-to-energy
+ specific problems of transport of hazardous wastes on land, air and
sea
+ pacticable collection systems
+ wastewater and sludges use, composting
+ reuse of tyres, waste-paper, packings, etc.
+ hazards of waste batteries, neon tubes, refrigerator-liquid,
synthetics, etc.
+ greenhouse gases
The following types of posts are strictly PROHIBITED in this newsgroup:
* Material and advertisments unrelated to conditioning, recycling, and
impact of wastes (off-topic)
* Spam (defined as articles posted to more than 5 newsgroups)
* Make-money-fast or other chain or fraudulent schemes
* Forged posts (anonymous posts are allowed)
* Personal insults or repetitive flaming (attacks)
The use of e-mail addresses from articles posted to this group for the
purpose of sending junk (mass unsolicited) e-mail or for compiling a
list so that others may do so is specifically PROHIBITED.
Binaries are only allowed by adding format or extension in the subject
line. On-topic advertising and employment (help and/or position wanted)
noticesis are limited to once per week. Please send such post only on
fridays.
Discussions about saving the nature without context to wastes should
better
take place on sci.environment or sci.bio.conservation, and the talk
about
energy-production (with the only exception of waste-to-energy
discussion)
and production techniques (with the only exception of waste reduction in
the
production-process) should better take place on sci.energy or on the
sci.engr hierarchy.
The general "netiquette" FAQs posted in news.announce.newusers and
news.answers apply to the proposed group. Participants are encouraged to
use descriptive Subjects (e.g., "Burning PCBs" rather than just "Help"
or
"Question").
In the absence of moderation, prohibitions can, of course, only be
enforced by the collective will of the group and/or by after-the-fact
complaints to the offender's service provider.
END CHARTER.
HOW TO VOTE:
Follow these instructions *exactly*! Votes are counted by computer.
You should send E-MAIL (posts to a newsgroup are invalid) to:
voting@hut.fi
Just replying to this message won't work.
Check the address before you mail your vote. Your mail message
should contain one and only one of the following vote statements:
I vote YES on sci.environment.waste
I vote NO on sci.environment.waste
Voter name:
If your mail software does not indicate your real name (for example, AOL
and
Delphi do not), include _exactly_ the statement above on a _separate_
line
and add your name after the colon. Having your name in your signature
line
is NOT enough! Do NOT join the lines together or remove the words
"Voter name"!
You may also vote ABSTAIN (which does exactly that) or CANCEL (which
removes any earlier votes). ABSTAIN does not affect the final vote
count
in any way but is listed, whereas CANCEL is not.
IMPORTANT VOTING PROCEDURE NOTES:
Standard Guidelines for voting apply. One person, one vote. Votes
must be mailed directly from the voter to the votetaker. Anonymous,
forwarded or proxy votes are not valid. Votes mailed by WWW/HTML/CGI
forms are considered to be anonymous votes.
Vote counting is automated. Failure to follow these directions may
mean that your vote does not get counted. If you do not receive an
acknowledgment of your vote within three days contact the votetaker
about the problem. It's your responsibility to make sure your vote
is registered correctly. Duplicate votes are resolved in favor of
the most recent valid vote. Addresses and votes of all voters will
be published in the final voting results post.
The purpose of a Usenet vote is to determine the genuine interest of
persons who would read a proposed newsgroup. Soliciting votes from
disinterested parties defeats this purpose.

Hello from Maine!,
My name is Grant and I am a undergraduate sophmore at the
University of Southern Maine. I am currently taking my first soils
class and find it very enjoyable. I enjoy it enough to have
volunteered to assist in a research project. The research project
involves the comparison of two different types of soil water
samplers, the porous ceramic cup type and the teflon and steel type.
The brands that are being used are Soilmoisture and Prenart,
respectively. I was wondering if anyone had performed research with
these two different types of lysimeters before and had found any
differences in any of the areas that are involved with using them,
such as; cleaning, installation, and test results. I have conducted
some library research, but have yet to come up with anything that
would be geared towards what I am doing. Any help with this would be
greatly appreciated. Also I am looking for any information on a bulk
density sampler that is or was made by a company named Uhland. If
the name has changed or the sampler is being produced by a different
company, I'd appreciate any information on that. Thanks for your
time in advance and if I made any dumb mistakes with this, please
excuse them, my computer skills are in the Fred Flintsone category.
Waiting for winter to end,
Grant Delaware

At AgResearch we have developed fertiliser recommendation software
specifically for pastoral agriculture in New Zealand. The Outlook (TM)
decision support software has been designed for the evaluation
of P and S fertiliser strategies by farm consultants in conjunction
with their farmer clients. The software is licensed to farm
consultants through the AgResearch Soil Fertility Service.
The underlying dynamic model is based on the P and S cycles in the
soil-plant-animal system, including fertiliser inputs and soil and
animal mediated losses. Initial soil fertility is estimated from the
Olsen P and phosphate extractable organic S soil tests, and recent
fertiliser history. In the sulphur submodel organic S, sulphate and
elemental S pools are considered. Animal production responses to
fertiliser are estimated from relationships between soil P and S
status, fertiliser inputs, relative pasture yield and stocking rate.
Maintenance and economically optimum fertiliser strategies can be
automatically calculated or the user can enter their own scenarios.
Alternative fertiliser policies can be evaluated in terms of nutrient
budgets, soil P and S status, pasture and animal production, and
economics.

Fraudulent Chain Letter
This statement may be copied or reprinted by online users
The American Cancer Society is greatly disturbed by reports of a
fraudulent chain letter circulating on the internet which lists the
American Cancer Society as a "corporate sponsor" but which has in no
way been endorsed by the American Cancer Society. This letter appears
to have started on America Online but has now spread well beyond the
online service. There are several variations of this letter in
circulation. The text of the original message reads as follows:
LITTLE JESSICA MYDEK IS SEVEN YEARS OLD AND IS SUFFERING FROM AN ACUTE
AND VERY RARE CASE OF CEREBRAL CARCINOMA. THIS CONDITION CAUSES SEVERE
MALIGNANT BRAIN TUMORS AND IS A TERMINAL ILLNESS. THE DOCTORS

PLEASE GIVE JESSICA AND ALL CANCER VICTIMS A CHANCE.
IF THERE ARE ANY QUESTIONS, SEND THEM TO THE AMERICAN CANCER SOCIETY
AT ACS@AOL.COM
As far as the American Cancer Society can determine, the story of
Jessica Mydek is completely unsubstantiated. No fundraising efforts
are being made by the American Cancer Society in her name or by the
use of chain letters. Furthermore, the email address ACS@AOL.COM is
inactive. Any messages to the American Cancer Society should be
instead sent through the American Cancer Society website at
http://www.cancer.org.
This particular chain letter with its heartbreaking story appears to
have struck an emotional chord with online users. Although we are very
concerned that the American Cancer Society's name has been used to
manipulate the online public, we applaud the good intentions of all
who participated in this letter. We are pleased to note that there are
so many caring individuals out there and hope that they will find
another way to support cancer research. Jessica Mydek's story, whether
true or false, is representative of that of many cancer patients who
benefit daily from the efforts of legitimate cancer organizations
nationwide.

Subject: Relationship between OC & OM
I'd like to pick some brains:
First, I was told originally that you multiply o.c. X 1.712 to get
organic matter; however, I was later told that you multiply o.c. X 2 to
get organic matter. What is the correct value?
Second, it is my understanding that sulphur is chemically similar to
oxygen. (For example, chemosynthetic critters substitute sulphur for
oxygen in chemosynthesis). Therefore, can a high concentration of
sulphur function like an electron acceptor like oxygen and create
oxidizing conditions in an anoxic soil?
Thanks in advance.

The question is if you are looking for organic matter
content or humic substances content.
Since humic substances contain mean 58% of carbon,
you can multiply organic carbon x 1,724 to calculate
the humic substances content.

Richard,
One thing to keep in mind is that most of the research on this has been
focused on the upper (A) strata of the soil, due to the agronomic bias in
soil research. This horizon contains organic carbon (and organic matter) of
different ages. In general, the calculated constant is based on the mean of
all these different aged carbons. A vast difference in the constant can be
found between fresh organic matter, a well evolved A-horizon, and a buried
paleo-A horizon. For background on this aspect of organic carbon please
visit the OCR Carbon Dating Web-site at:

Richard,
The question is if you are looking for evaluation of the organic matter
content or humic substances content.
Since soil humic substances contain mean 58% of carbon,
you can multiply organic carbon x 1,724 to calculate HS content.

Jerzy

Richard;
Theoretically, anything that can accept an electron could take the role of
oxygen as your described. However, there are only a few chemical species
that commonly do this in soils and water. These include nitrate, sulfate,
manganese, iron, hydrogen, and carbohydrates.
The energetic sequence of electron acceptors following the elimination of
gaseous oxygen from a submerged soil, for instance, are as follows. They
will not necessarily follow in this order in reality, since some are
solid-phase (Manganese oxide), some are typically dissolved in water
(sulfate), and some are gaseous or dissolved in water (oxygen). Gaseous or
dissolved electron acceptors can move around by diffusion, whereas
solid-phase species force microbes to move to them.
I'm not sure whether or not elemental sulfur will be reduced in an anoxic
soil. Theoretically, it could be, but I have not encountered this
happening. It certainly oxidizes in the presence of gaseous oxygen, and is
often used to acidify soil in this way. Once it is present as sulfate, it
is often an important electron acceptor in anaerobic soils as shown below.

The factor 1.724 (or 1.712) is only a tradition.
In Italy we use 1.724 only because it is the same number applied by official
analytical methods for organic fertilizer.
There is not a correct number (or a magic number).
Remember also that generally it is used a correction factor for the organic
carbon not recovered. It ranges from 1.19 to 1.33.
See:
D.W. Nelson and l.E. Sommers. 1982. Total carbon, organic carbon and organic
matter. p. 539-579 In: Page A.L., R.H. Miller e D.R. Keeney (ed.). Methods
of soil analysis, Part 2. Chemical and microbiological properties 2=AA ed.
Agronomy 9 part 2. Am.Soc.of Agronomy - Soil Sc. Soc. of America. Madison,=
WI.=20
expecially page 567-568.
I think that, as for available nutrient, organic carbon soil test is only an
index. The main problem is the interpretation of the results of soil=
analysis.
Sincerely.
Marino
