Title:
Analysis of site-specific N balances in heterogeneous croplands using digital methods
Abstract:
In this study, the spatial variability of nitrogen (N) balances were determined on heterogeneous arable fields in southern Germany using digital methods (combine yield sensing system, tractor mounted multispectral sensor and satellite data, vegetation indices, and models). The aim of this study is to precisely localize N surplus and nitrogen loss potentials through a high spatial resolution. The spatial variability of plant properties (yield, N uptake) were determined in order to calculate the N...     »
