In-season prediction of crop nitrogen status
This new technology can estimate CNS (crop nitrogen status) using remote sensing and the nitrogen nutrition index (NNI). These estimates produce actionable insights on the optimum nitrogen fertilizer use efficiency to maximize agronomic production. This new system helps forecast end-of-season crop yield and quality. For example, remote sensing based CNS measurements on a given date can forecast end-of-season crop yield and quality for a given field—and within a field. While this precision agriculture technology was developed for irrigated potato cropping systems, it could be adopted for use in other high-value agronomic or horticultural crops.
Precision nitrogen applications for intensively managed crops
Remote sensing offers superior temporal and spatial resolution that can supplement or even replace existing methods for managing in-season nitrogen applications. While the adoption of remote sensing in precision agriculture is rapidly accelerating, no system to date can directly and accurately determine crop nitrogen status (CNS) from remote sensing alone. Previous methods have relied on imagery to directly predict CNS. However, these methods lack accuracy and may require an in-field reference strip, which is logistically challenging. Remote sensing, on the other hand, can more accurately predict both CNS as well as other parameters (e.g., canopy cover or above ground nitrogen concentration).
