Alterna Biocarbon and Cowboy Charcoal Virginia field trials '09

Field Trials;
 I am field testing for the 09 corn season with JMU and consultation  Dr. Hepperly at Rodale Institute.

Ten research priorities were identified at the IBI conference, The following priorities I hope to address:
• 1- Economy research/market research
• 2- plant+soil research depending on biochar
• 5- field trials
• 8- application to soil (depending on agricultural or other
systems/remediation`)

Planting date: June 24th.
Two split plots , which each are split into a 20% (27 tons/Ac) & 5% (7 tons/Ac) application rates,
All chars soaked in tarps for 1 month, all chars were mixed 1:2 by volume with finished poultry litter compost and roto-tilled to 5 inch depth.

Knowing when plants capture phosphorus

Knowing when plants capture phosphorus
Luis Pons, USDA Agricultural Research, Jan, 2003
ARS research into how and when plants use the phosphorus in manure may aid farmers as they try to stem nutrient runoff into waterways.
"A future challenge," says soil scientist Thomas J. Sauer, "will be not only to avoid over-application of phosphorus to soil, but also to ensure that in doing so a farmer does not make the land phosphorus deficient."
Sauer and soil scientist John L. Kovar focus on phosphorus as they study nutrient management of animal manure at ARS' National Soil Tilth Laboratory in Ames, Iowa.
This research is part of Water and Quality Management, an ARS National Program (#201) described on the World Wide Web at http://www.nps.ars.usda.gov.
Thomas J. Sauer and John L. Kovar are with the USDA-ARS National Soil Tilth Laboratory, 2150 Pammel Drive, Ames, IA 50011-4420; phone (515)294-3416 [Sauer], (515)294-3419 [Kovar], fax (515) 294-8125, e-mail sauer@nstl.gov.kovar@nstl.gov.

Soil Testing and Available Phosphorus

Soil Testing and Available Phosphorus
Antonio Mallarino, assistant professor and John E. Sawyer, associate professor, Department of Agronomy, John Creswell and Michael Tidman, Iowa State University, September 2000

This article is the continuation of a series of articles that provides producers with information that aids in phosphorus (P) management. We address the following: soil testing as a tool, trying to predict availability of P for crops, agronomic testing for P, environmental testing for P versus agronomic testing for P, and environmental perspective and interpretation.

Phosphorus Facts - Soil, Plant and Fertilizer

Phosphorus Facts - Soil, Plant and Fertilizer
David Whitney, Kansas State University Cooperative Extension Service, C-665, October 1988
Phosphorus (P) does not exist in soils in the simple elemental form, but is found combined with other elements forming complex minerals (inorganic)and organic compounds. The total phosphorus content of the surface six inches may be as little as 200 pounds per acre on very sandy soils to over 2,500 pounds per acre on fine textured soils.
However, only a small fraction of this total phosphorus is in a form that is readily available to plants. Thus, application of phosphorus fertilizer, or agricultural or municipal wastes are necessary on many soils to meet plant phosphorus needs.
