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.

Properties:

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.
