The LANDSUPPORT best practices tool identifies optimized solutions for the health of agricultural soils

In the LANDSUPPORT project (H2020-RUR-2017-2/No. 774234), we have developed a web-based "Best Practices tool" that runs on the fly (https://dev. landsupport. eu/template. html) to identify optimized solutions for enhancing soil fertility and reducing nitrate leaching. The tool works at a regional scale (average area of approximately 2500 km 2) in three case studies (Marchfeld-Austria, Campania Region-Italy, Zala County-Hungary) with a what-if scenario approach. The tool is dynamically linked to the ARMOSA process-based model, which simulates at a daily time step many combinations of farming systems (conservation, organic, conventional), crops, nitrogen fertilization rates, tillage solutions, crop residues management (up to 2520 combinations). ARMOSA simulates crop growth, soil water dynamics, nitrogen and carbon cycling......
