1. 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. 

  2. 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.
