Date: Thu, 30 Nov 1995 10:15:48 -0600 From: jocke@texoma.com (John Ockels) Subject: Chemical residues in compost I would appreciate any help you might be able to give in answereing this question from a local (North texas) backyard composter: "We use a popular horse worm medicine called Zimecterin (Ivermectin) Paste 1.87%. Does the active chemical in this worm medicine persist in compost whose food stock includes manures from horses doctored with this substance?" This product is distributed by the Farnam Companies in Phoenix. I would add that these folks who ask this question are wonderful organic farmers and would deeply appreciate any help you could provide. Thanks in advance for your consideration.

Date: Thu, 30 Nov 1995 15:21:30 +0000 (GMT) From: "Y.Zhou" .<.Y.Zhou@geo.hull.ac.uk.>. Subject: conference hunting Hi Friends I am currently involved in a project on the relationship between erosion and slope vegetation. The study focuses on the roles of a pine forest on erosion control and slope stabilization in a gorge. I have been hunting a conference in which I could introduce the preliminary result of this study and share some idears with other colleages. A very intereting conference called 'VEGETATION AND SLOPE STABILIZATION' has been hold in Oxford, UK, last September. Is anybody know any information about the coming-soon conference of this kind or similar? I would be appreciated very much if he or she could offer me the information. Thank you very much for your friendly help! ----------------------------------------------------------------- Yue Zhou School of Geography and Earth Resources The University of Hull Hull, HU6 7RX, UK Tel: (44) 1482 466332(at office), (44) 1482 803607(at home) Fax: (44) 1482 466340, Email: Y.Zhou@geography.hull.ac.uk ----------------------------------------------------------------- <------------------------------>

Date: Fri, 01 Dec 1995 12:56:44 +0100 From: Torsten Muller .<.Torsten.Muller@agsci.kvl.dk.>. Subject: Chemical residues in compost -Svar There is a lab in Germany that made a lot of research in compost-quality and organic farming which maybe can help to get informations about persistence of organic residues (medicine) in compost: Universitaet Kassel Fachgebiet Oekologischer Landbau Nordbahnhofstr. 1a D-37213 Witzenhausen phone: +49 5542 981565, fax: +49 5542 981568 The knowledge about persistence of organic residues in compost is very poor in general. Unfortunately a lot of researchers dealing with compost are publishing in very small journals. So, if anybody has some brand new results, it could be interesting to hearing about that here.

Date: Sun, 03 Dec 1995 18:42:22 +0000 From: alexander.nidorf@linacre.oxford.ac.uk (Alexander Nidorf) Subject: Soil moisture modeling Currently I'm a graduate student at the Environmental Change Unit, University of Oxford. As part of masters thesis I'd like to model the effects of projected climate change on agricultural output in the Imperial Valley, California. I need some advice on modeling soil moisture and evapotraspiration in extreme conditions. If anyone has any experience in this area I'd like to ask: 1. What models have been developed to predict the effects of climate/temperature on irrigation? Have irrigation models been developed that can be used for this sort of study? 2. What soil and/or crop models deal well with heat stress and drought? I'll be in El Centro over Christmas. If anyone on this list lives in the Imperial Valley or San Diego County areas please let me know. I'd like to discuss these issues further with someone working in the area.

I have a question concerning aqua regia in soil analysis: Does someone on the list have an idea about the theory and background for analysing soil nutrients in aqua regia. It is the macro- and micro soil- cations that I have analysed in a project concerning forest soils, but I need some more information of how, and why this strong acid is used for analysing soil samples and what fractions of the cations is extracted. I would be gratefull for any information or fx selected litterature about the subject.

Among other products our company makes a line of emulsion and solution copolymers of acrylamide. About two years ago Janet Roloff had an article in Science News (Science News, Vol. 144, pgs 280-1) about using polyacrylamide to halt soil erosion in irrigated fields. Always on the lookout for possible new markets for our products, I did some literature searching, but could only find some articles dating back to 1986 in Soil Science. Unfortunately, I got tied up in some other things and didn't have a chance to follow-up at that time. Is anyone still working on this type research? If so, I would be interested in getting some pointers to some literature sources or possibly contact with a researcher.

Date: Tue, 05 Dec 1995 11:03:39 +1300 From: Dean Stewart .<.STEWARTD@tui.lincoln.ac.nz.>. Subject: Fertilizer N reducing the rate of OM mineralization Some results from a laboratory incubation I did have shown that adding N fertilizer decreased the rate of N mineralization from mushroom compost amended soils. I am aware of other work that has found added N may reduce the rate of organic matter decomposition (i.e. reviewed by Kare Fog in Biological Reviews 1988, 63:433-462). This latter work is mainly on organic materials with high C:N ratios and lignin contents, and low N contents. In contrast mushroom compost has a C:N of 18 and contains 1.8% N, however the organic N it contains is resistant to mineralization. Has anyone found similar results to these with composts or other organic materials of similar quality ??? Dean Stewart AgResearch c/- Department of Soil Science Lincoln University P.O.

Date: Wed, 20 Dec 1995 21:08:51 +0000 From: M.Turner@massey.ac.nz (Max Turner ) Subject: Looking for collaborators Dear Listers I would like to use the list for something a little different and I hope you can assist me in my search. I am looking to identify a small group of Soil Science lecturers (especially in the soil fertility/fertilisers/land use areas) from a number of different, english speaking countries. Probably some of the people I need to know are not even current subscribers to this list, in which case you may be able to assist me by mentioning this note to the appropriate person(s). What I am looking to do is to offer these potential collaborators an opportunity to participate in an exciting international educational opportunity (details of which I am happy to elaborate once an expression of interest has been received). I hope to make contact with a global group of soils lecturers who are as enamoured as I am with the use of the computer as an educational tool. If you are of like mind then please contact me and acquaint me with your interest in participating, together with your skills and special area of expertise in Soil Science. For those with an interest in cooperation, but who possess limited computer skills, I am prepared to do much of the development work if your area of special interest is appropriate to the project; so lack of computing skills need be no deterrent. All told I hope to identify at least 10-12 enthusiastic lecturers, teaching students at around the 300-400 level soils (ie students with at least some basic understanding of how soils work) or at the post-graduate level, from a number of different countries and climates. If this sounds interesting to you please take the time to contact me at Massey University (in New Zealand). Incidentally this initiative has the support and backing of the Professor of Soil Science (Prof Russ Tillman), the Dean of the Agricultural and Horticultural Faculty (Prof Robert Anderson) at Massey University, so it is a legitimate undertaking. I look forward to hearing from you if you wish to be involved. Sincerely Max Turner (Senior Lecturer in Soil Science) Please reply by email to: M.Turner@massey.ac.nz <------------------------------>

Date: Thu, 21 Dec 1995 07:28:46 -0600 From: jaartz@blue.weeg.uiowa.edu (Joe Artz) Subject: Re: CO2 Emissions In reply to Patrick Joyce, concerning the rates of wasteage and CO2 emissions as organic matter is lost from a soil. He doesn't tell us the time scales he's interested in, but my interest in this topic involves time scales on the order of 100-10,000 years. When an A horizon becomes buried, and therefore removed from additions of carbon from decaying organisms, etc., it begins to lose organic carbon. In the following three studies, organic carbon in buried soils was compared with that of a nearby, surface A horizon that was not buried. In all three studies, burial was caused by anthropogenic factors. Hallberg et al. (1980) Proc. Soil Sci. Soc. America 42:339-343 Time of burial: 100 years beneath spoils from railroad cut Carbon content of surface A: 2.6% Carrbon content of buried A: ca. 1.5% Loss: 42% Mattingly and Williams (1962) J. Soil Sci. 13:254-258 Soil buried 1500 years under Roman amphitheater Buried A: .77-.8% organic carbon Surface A: 2.4% Loss 68% Gardiner and Walsh 1966 Proc. Royal Irish Acad. 65C:29-35 Soil buried 4000 years under burial mound Buried A: 1.1% Surface A: 4.9% Loss: 78% My impression is that the rate of decay is greatest in the first 100 years following burial, but then begins to become more gradual. Organic carbon bound tightly with clays would be the last to be lost, and can stay around for 10s of thousands of years. My literature on this subject is very out-of-date. Maybe others on the list can add some more recent sources. I'd be interested in hearing them. <------------------------------>

Peter, Bioremediation of petroleum contaminated soils has proven to be an effective remediation technology. It is however, not suitable for all soil types or for all types of petroleum products. As with any remediation technology, there are limitations which must be examined prior to implementation to ensure that remediation goals are met. There are many good references on this subject, and I would be happy to provide you with a list of references in you desire. I am employed by an environmental consulting firm and we have had very good success bioremediating petroleum contaminated soils.
