Circular Agronomics (CA) provides a comprehensive synthesis of practical solutions to improve the current carbon, nitrogen and phosphorus cycling in European agro-ecosystems and related up and downstream processes within the value-chain of food production. CA is a frontrunner project exploiting affordable solutions to meet, among others, the requirements of agriculture, water and waste legislations as well as the EU policy targets regarding emission reduction (mainly NH3, NOx and GHG: CO2, CH4, N2O). The policy analysis contributes to market innovations, to sustainability and European initiatives and finally also to the development of effective joined up policy - further steps towards integrating agriculture in circular economy.
