Agriculture is responsible for around 80% of all nitrous oxide (N₂O) emissions in Germany. The largest source of N₂O in agriculture is the use of nitrogen fertilizers. Nitrification inhibitors are proposed as a measure to reduce greenhouse gas emissions in crop production. However, whether this is an efficient, practicable and environmentally friendly measure to reduce fertilizer-related N₂O emissions under Central European conditions is a matter of heated debate in science, politics and practice.
The aim of the joint project NitriKlim is therefore to comprehensively examine and evaluate the opportunities and risks of nitrification inhibitors.
