The main objective of Nutribudget is to develop and implement a prototype of an integrated nutrient management platform, called Nutriplatform, in various regions across Europe, as a decision-support tool (DST) for farmers, advisors and regional authorities. The development of Nutriplatform (WP5) will be based on knowledge from existing (WP1) and new field-tested agronomic mitigation measures (WP4) linked to advanced Nutrimodels that integrates various nutrient models, common data standards (WP2) and relevant monitoring indicators (WP3). Thereby, Nutribudget will contribute to systemically optimize nutrient flow and budget across different agricultural production systems and regions in the EU to limit and reduce pollution due to the excess of nutrients and nutrient losses in the environment
