Improved nitrogen use efficiency in agriculture by catch crops as producers of biological nitrification inhibitors (CATCH-BNI) - CH0221

Th CATCH-BNI project will investigate the incorporation of catch crops with BNI (biological nitrification inhibitor) potential into crop rotations as a mitigation strategy to slow down nitrification processes and retain ammonium in soils as well as to increase soil N pools for the subsequent target crop.
The main objective of the CATCH-BNI project is to design innovative approaches enabling the slow and controlled conversion of NH4+ into NO3- (and later into N2O) in soils for optimal nutrition of target crops. The primary objectives are:

1. Identifying new plant species and/or cultivars with BNI activities in their root exudates and/or root and shoot tissues;

2. Understanding how efficiently the N cycle is impacted by the use of BNI-producing catch crops and how the target crops perform (yield and NUE);

3. Determining the best options and modalities to stabilize organic fertilizers with BNI plant material and

4. Validating in real field conditions the proposed innovations.
