Nitrogen Leads Fall 2019 Fertilizer Rates Decrease
The quadratic portion of the response curve produces diminishing returns – as every single extra unit of N is applied, less yield is developed. MERN occurs exactly where the subsequent unit of N no longer supplies sufficient yield response to pay for its price, typically occurring a small just before maximum yields (Fig. 1). Rodale, with assistance from the Pennsylvania State University, has been conducting side-by-side comparisons of conventional and…Read More
