Objective: To develop innovative, ecologically-based crop and soil nutrient management practices for enhanced productivity and negligible off-site agricultural impacts.

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

Joint Research Project to Use Ancient Amazonian Farmland Soil Enrichment Techniques

ARLINGTON, Va. -- Dynamotive USA, Inc., a wholly-owned subsidiary of Dynamotive Energy Systems Corporation (OTCBB:DYMTF), a leader in biomass-to-biofuel technology, announced it is taking part in a project to test biochar, a co-product of the company's BioOil([R]) biofuel, as a soil enhancer to increase fertility and corn crop yields.
The project is led by Heartland BioEnergy LLC, based in Webster City, Iowa. Heartland proposes to build a biorefinery in central Iowa that would include a BioOil([R]) and biochar plant developed in partnership with Dynamotive and several agriculture equipment companies.
