Agrosystems in industrialised countries are facing increasing food demand while having to reduce external inputs and minimise negative environmental impact. The widespread use of synthetic nitrogen (N) fertilisers promotes the productivity and profit in agricultural plant production. However, due to the low nitrogen use efficiency (NUE) of crop plants, it entails losses from the plant-soil system via NO3- leaching and/or N gas emissions leading to soil, water and atmosphere pollution.
While chemical inhibition of nitrification has emerged as a tool to limit nitrate losses, several plant species display nitrification inhibiting activities, mostly through release of organic compounds present in their root exudates named Biological Nitrification Inhibitors (BNIs).
The main objective of the CATCH-BNI project is to design innovative approaches enabling the slow and controlled conversion of ammonium into nitrate in soils for optimal nutrition of target crops:
