Brief Project Summary:

An important parameter of the Ohio P Index is fertilizer/manure placement method. This work intends to be complementary and to accelerate the evaluation and revision of how the fertilizer placement factor is weighted and scored, which will contribute to the ongoing effort to evaluate and revise the Ohio P Index. Research aims to evaluate differences in surface runoff of phosphorus, nitrogen and suspended sediment based on fertilizer placement methods across varying P sources, including both liquid and dry fertilizer and manure, and levels of residue cover.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Final Project Results

Update:
All Yr 2 work and analyses are complete for P, N, & suspended sediments. We had hoped to add 1 more field treatment this fall (yr3) however due to personnel shortage, weather and the fact that they still haven't harvested we will not be doing field work this fall. We may try to revisit this in the spring, prior to planting and I will dicuss with Harold. Data from this work was instrumental in revising Ohio P Index fertilizer/manure application methods.

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.
