  1. Organic Farming Research Foundation Grant Awarded to OSU Soil Fertility Lab

    Apr 18, 2017

    The Organic Farming Research Foundation (OFRF) has recently announced the recipients of their 2017 research grant awards. We’re very excited that the OSU Soil Fertility Lab was one of five research groups from across the nation to be awarded a grant from OFRF for our project entitled, “Evaluating Soil Protein as a New Soil Health Indicator”. Our lab focuses on quantifying various aspects of soil health and with this grant we are hoping to develop better predictive tools of organic matter nitrogen supply to plants based on rapid and affordable soil metrics. The research project will further our understanding of the newly emerging soil health measurements in organic cropping systems. We will work with organic farmers on evaluating, communicating, and interpreting soil health test results, as well as developing factsheets focusing on soil health testing on organic farms. We are excited to begin this research and believe this project has the potential to positively impact nutrient management on organic farms in the Midwest and surrounding regions by furthering the development of rapid and affordable soil health tests.

     

     

     

  2. There's still time to enroll in our fertilizer recommendation trials!

    Apr 11, 2017

    We are still accepting cooperators for our fertilizer recommendation trials. This project is focused on addressing agronomic and environmental concerns with a robust and widespread re-evaluation of the Tri-State Fertilizer Recommendations. Learn more about our project: Updating Fertilizer Recommendations. If you're already familiar with our project and want to become involved, follow this link to sign up.

  3. Anthony Fulford and Steve Culman publish paper on fertilizer recommendations

    Mar 20, 2017

    The most recent fertilizer phosphorus (P) and potassium (K) rate recommendations for corn and soybeans grown in Ohio were published in the mid-90s and follow the buildup, maintenance, and drawdown approach. Validation of recommendations using today's farming practices is needed. In this study, fertilizer P and K application rates estimated to equal or exceed crop removal were applied and resulting corn and soybean grain yield and soil test P and K trends were observed throughout nine years of production at three sites in Ohio. 

  4. Tunsisa Hurisso and Steve Culman publish paper on organic matter stabilization and mineralization

    Mar 10, 2017

    Tunsisa and Steve recently published a paper on their work in active organic matter. In their manuscript, they examined the relationship between POXC and mineralizable C across a wide range of soil types, management histories, and geographic locations in the U.S. They also investigated the ability of POXC and mineralizable C to predict crop yield and total aboveground biomass.
