Soil organic carbon (SOC) has a vital role to enhance agricultural productivity and for mitigation of climate change. To quantify SOC effects on productivity, process models serve as a robust tool to keep track of multiple plant and soil factors and

Quantifying the transport and fate of dissolved nitrogen at different scales in drained agricultural landscapes

Autor: Nagy, David

Publikováno v: Nagy, D 2020, Quantifying the transport and fate of dissolved nitrogen at different scales in drained agricultural landscapes . Aarhus Universitet .

Nitrogen (N) is an essential part of the agricultural crop production cycle. Farmers generally apply high amounts of N-fertilizer in order to secure the high crop yield, which potentiallyincreases the risk of N-loss from the root zone. In order to ke

More user-friendly methods are needed to detect crop N status/stress and guide the timing of in-season N application. In the current study, a reference curve method of detecting N stress was proposed to remedy practical problems of methods that requi
