1. Investigating the Effects of Tillage Practices and Fertilizer Placement Strategies on Corn Yield and Nutrient Uptake in Eastern South Dakota

In South Dakota, phosphorus (P) and potassium (K) fertilizers are often used to optimize corn (Zea may L.) grain yields and maintain soil fertility. The placement of these fertilizers often has an impact on the nutrient accessibility to the plant and the fertilizer’s impact on the environment.  The management of these fertilizers is largely influenced by the tillage system utilized. In the western corn belt, producers have historically used a combination of conventional an... C. Tesch, P. Kovacs
