The long-term interaction between precision fertilizer placement, tillage systems, and plant nutrient cycling affect the distribution of nutrients in the soil. This presentation will discuss the implications for soil sampling and the development of accurate field data for variable-rate nutrient applications. Also, soil test interpretations as well as crop productivity and profitability under long-term precision crop management.
