Remote sensing-informed variable-rate nitrogen management of wheat and corn: agronomic and groundwater outcomes

In-season, site-specific, variable-rate (SS) N management based on remote sensing (RS) may reduce N losses to groundwater while maintaining or increasing yield and N fertilizer-use efficiency. We compared in-season, RS-informed N management applied on a uniform, field-average (FA) or SS basis with t...
