Adaptive nutrient management is a new feature in the revised NRCS code 590. This paper will explain what adaptive nutrient management is and how to implement it.
The goal of adaptive management is to enable growers to use on-farm data to refine nutrient management strategies to adapt to conditions on their farm. Adaptive management in the context of the 590 standard can be used to 1) document the need for and amount of rescue N applications after excessive rainfall; 2) adjust P and K application rates when documented crop yield levels are greater than ranges provided in UWEX Pub. A2809; or 3) refine any nutrient application rate (primarily N) or management strategy using on-farm research data.
