    Ohio State is in the process of updating the Tri-State Recommendations, looking specifically at N, P and K in corn, soybean and wheat. This is a major undertaking that will require a collective effort from numerous extension personnel, crop consultants and farmer cooperators. We will cast a broad net to collect data from a large number of farms across the state to determine economically-optimum fertilization rates.

    Soil sampling for lab analysis is a critical aspect of effective nutrient management, as it provides valuable information on the fertility status of your soil. Many producers find that fall is an ideal time to sample soil for several reasons: 1) soils often have an ideal moisture range that makes sampling easy, 2) it gives producers ample time to apply fertilizer or lime before the next crop and 3) it helps ensure spring planting will not be delayed.

    Rain. Rain. Rain. With excessive rain, chances are good most fields across this state have lost more N than in a typical year.  But how much have they lost? Everything applied? Is all of the N fertilizer gone? Although it’s difficult to estimate, it’s very unlikely that the majority of the N applied has been lost.
