SyNE – System Nitrogen Efficiency – facilitates understanding of nitrogen-use efficiency indicators.

Agriculture must improve its nitrogen-use efficiency and reduce its nitrogen-balance surplus. To help stakeholders in agricultural sectors move in this direction, UMR SAS developed the SyNE digital tool. It facilitates understanding of nitrogen-use efficiency indicators (SyNE and RNE) and nitrogen-pressure indicators (SyNB). Farmers, agricultural advisors and researchers are thus able to assess production systems and recommend ways to improve them.
