Optimization of nitrogen management and improvement of ecological efficiency of rapeseed by sensor controlled subarea-specific nitrogen fertilizing
The nitrogen management of rapeseed cultivation is crucial for the ecological footprint of biodiesel. Methods of precision farming provide an approach to improving it.
Soil properties can exhibit significant small-scale heterogeneity. Subarea-specific nitrogen fertilizing adapts nitrogen additions for this and for the resulting small-scale variations of plant nitrogen demand. The project studies how much greenhouse gas emissions can be mitigated using this approach.
The project is geared towards agricultural praxis and consulting
The Technical University of Munich has established a field experiment with sub-area specific N fertilization. The Thünen Institute provides equipment and its strong expertise for greenhouse gas flux measurements and analyses to the joint project.
