Re: Movement of polluted water to a well . . . .
If the flow is Darcian, or close enough, the problem can solved with refer-
ence to any hydrology or soils textbook in about 30 seconds, so I presume
that there must be some reason to suspect more complicated, non-Darcian flow.
In that case, much more information would be required to supply an answer or
estimate. By the way, whose side is our A.G. on, the polluter or the folks with
the threatened well?

Good response Jonathan! I suspect field conditions may indicate
unsaturated flow and variable soil materials exist. Therefore the
estimate is very dependent upon a careful analysis of field conditions.
This of course will require the assistance of someone who can view the
site. I suggest the original correspondent look for qualified natural
resource consultants or university professors in her regional area for
assistance.

Subject: sensitivity on CERES-WHEAT
Hallo,
I am a Ph.D student and I am working on CERES-WHEAT v2.9 with some
crop data from central france. Has anyone out there could inform me
about the maximum values that the genetic coefficients could get ?
How we can check the sensitivity of the model to soil characteristics
in a multi-layer adopted soil-profile and to the applied Nitrogen
in the case of more than one fertilizer applications ? Should
the sensitivity in that case be applied only in one typical year
or in every year of our period considering the different Nitrogen
stress that appears in each growing season ?
I would really appreciate any response.

These experiences brought me to Oxford to study soil erosion, climate change, and how these factors will influence the adaptation of highland swidden agriculture (sounds fancy, but really I'm just a redneck who likes to live up in the mountains and play with dirt). I am interested in contacting people who are working in these areas (i.e. soil erosion and highland swidden farming), especially people who have experience in Southeast Asia. I am also interested in modeling soil erosion on sloped swiddens.

Subject: Crop residue management in irrigated cracking clay soils TO: Multiple recipients of list .<.soils-l@unl.edu.>. FROM: Nilantha Hulugalle, Australian Cotton Research Institute, Narrabri, NSW, Australia Degradation in soil quality is major problem in cotton-based farming systems of Australia, and in particular, the river valleys of north-western New South Wales (semi-arid climate, cracking clay soils inc. Vertisols) where a major proportion of Australia's cotton is produced. In general, corresponding yield decreases can be of the order of 10-30%, although in extreme cases yield losses of >90% can occur. Management systems whereby such degradation can be ameliorated and avoided are, therefore, of primary interest to many cotttongrowers and State Organizations as even a yield decrease of 10% represents a loss of $42.9 million (based on 1993 values) to the State of New South Wales. Past research has indicated several possible management techniques such as minimum tillage and sowing rotations for avoiding and ameliorating soil degradation in irrigated farming systems (in cracking clays). More recently, although surveys, consultations with individual cottongrowers and cottongrower organizations have indicated a widespread interest in utilizing combinations of minimum tillage and rotation systems to combat degradation in soil quality, a major bottleneck in their extension (particularly cereal rotation crops) to the industry is in managing/disposing of the large amounts of rotation crop residues under minimum tillage (in irrigated farming systems in cracking clay soils, inc. Vertisols). Comments made by cottongrowers at a series of workshops in November 1994 further indicated that little was known about (a) the "best" existing method of residue management; eg. burning, incorporation etc., and (b) the effects of these residue management systems on on-farm and and off-farm soil and water quality. We are planning to submit a proposal for an on-farm based project which will address some of these issues in irrigated farming systems. The research team includes soil physicists, a soil chemist, a soil microbiologist, 2 on-farm extension agronomists, a weed scientist and an economist. I would like to hear from any member of the SOILS-L group who is currently working or has any past research experience in the area of crop residue management in irrigated soils (particularly irrigated cracking clay soils) with a view to initiating a discussion on the subject.

A simple book on soils might be Building Soils for Better Crops by Fred Magdoff
. It is published by the University of Nebraska Press. I think is about $20,
US money. Its major focus is on organic matter management but gets into soil
basics and nutrient cycling. Brady is more complete, but this is more suitable
to the public. It is 176 pages.

Klaas, I recently taught a beginning soils course at a community college.
My students were in an environmental tech program. I used Soil Science
Simplified, 2nd. Ed., Milo I. Harpstead, et. al., Iowa State University
Press, 1988.
I am familiar with both the Brady soils book and Western Fertilizer
Handbook. The book I would recommend is between the two in complexity and
instructionally oriented. It is somewhat outdated with the classification,
but makes up for that in the clear writing style. This book might work out
for you in your instructional situation. Wes

Gershuny and Joe Smillie, is now available in a new, extensively revised
third edition. A practical introduction to managing soil for long-term
productivity, this reference provides useful guidelines for making
management decisions based on ecological principles, with minimal reliance
on "off-farm" fertilizers.
Sustainable agriculture aims to protect the soil's ability to
regenerate nutrients lost when crops are harvested. This regenerative
capacity depends on the diversity, health and vitality of the organisms
that live, grow, reproduce, and die in the soil.
The goal of ecological soil management is to enhance conditions for
the billions of microbes found in every gram of healthy soil. These
microscopic organisms supply plants with the necessary nutrients at the
right time, and in the right form and amount.
The authors describe good management of soil organic matter and
humus to achieve long-lasting soil fertility. These methods include the use
of green manures, crop rotations, on-farm composting, and mineral
fertilizers. Detailed information is given to help the farmer with
everything from collecting soil samples to using practical, on-farm tests
that measure soil structure, water-holding capacity, and fertility.
This guide also tells farmers how to improve their skills of
observation, evaluation and management, as they must when reliance on
purchased inputs is reduced. Specific "how-to" information is given for
monitoring and analysis of many practices, such as application of composts
and manures, interpreting soil test results, and crop responses to
different fertility programs.
In addition to soilbuilding techniques, "The Soul of Soil"
discusses recordkeeping, cultivation, weed control, maintaining nutrient
balances, and soil testing. For those who are considering or have already
implemented organic certification, this book will aid in planning farm
operations.
The authors are experienced farmers, farm advisors and writers. Joe
Smillie has worked worldwide as a consultant in ecological agriculture
since 1976. He is co-author of "The Orchard Almanac." Grace Gershuny edited
"Organic Farmer: The Digest of Sustainable Agriculture" from 1990 to 1994,
and recently joined the staff of the USDA's National Organic Program to
implement its accreditation program for organic certification.
"The Soul of Soil" includes many tables, a glossary, lists of
resources, and a bibliography. Published by agAccess, the 158 page book

Dear Nilantha
I am not a soil expert, however I am working in the soil water area. You have
not mention what type of irrigation you got going for the cotton fields. Did y
ou consider changing the type of irrigation you are using, if that is feasible?
Localized irrigation might limit the cracking compared to wetting larger portio
n of the field. Localized irrigation can but may not mean drip or micro irriga
tion.

Subject: RE: Soils Book for Horticulture Diploma Course
Klaas,
I too teach soils to students in a diploma of horticulture course at the Ryde
College of TAFE (Technical and Further Education), in Sydney, NSW Australia.
This course specialises in ornamental horticulture rather than fruit and
vegetables.
Our first year soil text is:
Growing Media for Ornamental Plants and Turf. Revised Ed (1994)
by Kevin Handreck and Neil Black.
University of New South Wales Press
22-32 King Street
Randwick NSW 2031
Australia
Phone: (02) 398-8900
Fax: (02) 398-3408
ISBN 0 86840 333 4
448 pp. Hardcover
Price: around $A35.00
This book was purpose-written here in Australia to provide relevant soils
knowledge for the ornamental plant grower. As well as providing the basic soils
information it has extensive chapters on Potting Mixes, Fertiliser use and
Soil-borne diseases in nurseries, Plant Containers, Composting, Managing Turf
Soils, Watering, and Hydroponics. It also has a chapter dealing with site
preparation in anticipation of planting out nursery stock into landscape
settings.
The book is aimed directly at the practical application of soil theory and so
has direct appeal to diploma level students. It contains some 30 simple tests
aimed to help horticulturists work with soils and other growing media.
We have been successfully using this book in its variuos editions for more than
10 years. It might be worth a look before you choose your text.
I'd be interested in hearing from you regards your final choice and more about
your teaching.
Cheers,
Derry Thomas

Subject: Crop residue management in irrigated cracking clay soils TO: Multiple recipients of list .<.soils-l@unl.edu.>. FROM: Nilantha Hulugalle, Australian Cotton Research Institute, Narrabri, NSW, Australia Degradation in soil quality is major problem in cotton-based farming systems of Australia, and in particular, the river valleys of north-western New South Wales (semi-arid climate, cracking clay soils inc. Vertisols) where a major proportion of Australia's cotton is produced. In general, corresponding yield decreases can be of the order of 10-30%, although in extreme cases yield losses of >90% can occur. Management systems whereby such degradation can be ameliorated and avoided are, therefore, of primary interest to many cotttongrowers and State Organizations as even a yield decrease of 10% represents a loss of $42.9 million (based on 1993 values) to the State of New South Wales. Past research has indicated several possible management techniques such as minimum tillage and sowing rotations for avoiding and ameliorating soil degradation in irrigated farming systems (in cracking clays). More recently, although surveys, consultations with individual cottongrowers and cottongrower organizations have indicated a widespread interest in utilizing combinations of minimum tillage and rotation systems to combat degradation in soil quality, a major bottleneck in their extension (particularly cereal rotation crops) to the industry is in managing/disposing of the large amounts of rotation crop residues under minimum tillage (in irrigated farming systems in cracking clay soils, inc. Vertisols). Comments made by cottongrowers at a series of workshops in November 1994 further indicated that little was known about (a) the "best" existing method of residue management; eg. burning, incorporation etc., and (b) the effects of these residue management systems on on-farm and and off-farm soil and water quality. We are planning to submit a proposal for an on-farm based project which will address some of these issues in irrigated farming systems. The research team includes soil physicists, a soil chemist, a soil microbiologist, 2 on-farm extension agronomists, a weed scientist and an economist. I would like to hear from any member of the SOILS-L group who is currently working or has any past research experience in the area of crop residue management in irrigated soils (particularly irrigated cracking clay soils) with a view to initiating a discussion on the subject.
