The Ohio State Soil Fertility Lab will be starting a number of projects this year that will only be successful with participation from farmer cooperators across the state. We are asking for your help with the projects outlined below.
1) Revising Fertilizer Recommendations in Corn, Soybean, and Wheat
We are 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 OSU 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 and determine economically-optimum fertilization rates to maximize farmer profitability.
Experiments will involve either applying additional fertilizer or no fertilizer to replicated strip plots. Farmers can choose which nutrient they’d like to work with and will have a large degree of flexibility in the plot layout and applied rates.
