Summary:
This Soybean Fertility module consists of two presentations. The Nutrient Uptake and Utilization presentation covers three areas of focus related to nutrient management. The first area of focus discusses the nutrients important for soybean production. The second answers the question, “How does pH influence nutrient management decisions?” And the third area of focus deals with the differences between macronutrients and micronutrients. The Fertilizer Application for Soybean presentation covers the following points: Additions of fertilizer can significantly increase the yields of soybeans meaning more profit for producers. In the Midwest phosphorus and potassium are most commonly needed to raise soybeans. Unlike other crops soybeans do not benefit from fertilizer placement. Broadcast fertilization is typically sufficient for soybeans even in no- or reduced tillage situations. Banded fertilizer can be used to supply nutrients but is not an advantage in terms of efficiency and banded placement such as starter fertilizer can be detrimental since soybeans are more affected by fertilizer placed close to the seed. Also, critical soil test levels tend to be lower with soybeans which can offer producers flexibility in when and how they apply fertilizer for soybeans.
