Brief Project Summary:

Phosphorous is non-renewable, scarce, exhibits high price variability, is expensive, and can cause substantial environmental impacts when discharged into fresh water systems. Soluble phosphorus from crop land can originate from manure and commercial fertilizers. Additionally, recent research ha shown that cover crop freeze/thaw cycles can leach soluble phosphorus as a result of plant tissue breakdown. Soluble phosphorus is quickly transported though macro pores. Once below the root zone and into tile drains, the phosphorus is essentially a lost resource. Results from a recently completed project are being formulated into the qualitative Practice Selector for Nutrient Retention Tool (PSNRT)....

Information And Results
Project Deliverables

The project will produce the MMCU and the associated protocol for the PSNRT. This protocol, and the software to support interpreting results from the MMCU, will be included on a tablet with a convenient user interface system. Additionally, 3 field days will be held to demonstrate the MMCU and the protocol. Further, data will be accumulated for future projects to qualitatively model nutrient retention in soil.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
