Recovery of mineral fertiliser N and slurry N in continuous silage maize using the 15N and difference methods

Abstract

The stable isotope technique and the difference method are common approaches for estimating fertiliser N uptake efficiency. Both methods, however, have limitations and their suitability may depend on N management and environmental conditions. A field experiment was conducted on a humus sandy soil in northern Germany to estimate fertiliser N uptake… (More)
