Implementation 1 of Phos4Cycle seeks to develop a common strategy and an action plan for the management of phosphates associated with agricultural and livestock activity in rural areas to improve agricultural practices by applying preventive measures to reduce the transfer of forms of phosphorus to the aquatic environment, as well as corrective measures in water masses with a polluting presence. Beneficiary No 4 CPI shall coordinate the joint work of all partners. In addition, the strategy will include specific guidelines for reducing phosphate pollution in different agro-livestock production systems. Each partner will contribute to the definition of guidelines in the systems experienced in each pilot: dairy production (IPC-CALCOB), horticultural production (IPC-CALCOB), irrigated cereal production (ITAGRA), dehesa production (FEDEHESA), permanent woody crop production (DGAG_GR) and poultry production systems (ITAVI), making them more competitive. All these production systems are essential in the economy of the SUDOE area. The Action Plan, jointly developed by the partners to facilitate the adoption of the strategy, will then be adapted by each partner into a roadmap for each territory (WG3).
