Estimating plant nitrogen status in irrigated corn using ground-based and satellite data

Estimating plant nitrogen status in irrigated corn using ground-based and satellite data

Proceedings of the 7th International Conference on Precision Agriculture and Other Precision Resources Management, Hyatt Regency, Minneapolis, MN, USA, 25-28 July, 2004: 1429-1441

In-season N management of irrigated corn requires frequent acquisition of plant N status estimates for timely assessment of the onset of crop N deficiency and its spatial variability within a field. Satellite-based sensors have not had adequate spatial resolution, repeat coverage, and image delivery time for intensive agricultural management. The high-resolution QuickBird satellite may potentially change these limitations.
