The source of brought-in manures is restricted by the positive list of admitted fertilizers in organic farming. For export of manure from the own operation of more than 1 LSU/year, a contract must exist with the farm receiving this manure. This farm must be managed according ecological principles and can not exceed adequate nutrient limits as set by the legislation.


Import of farm yard manure and compost can only occur if a contract exists with the exporting farm and nutrient needs of crops are not exceeded (evidence must be provided by calculation). The EU Regulation 2092/91 limits the nutrient input of farm yard manures to 170kgN/ha; while neither of the farms (the exporting farm and the receiving farm) may exceed this limit.


Organic farming should be performed based on the principle of a closed system with self sufficiency in fertilizer supply but no excessive manure should be produced nor applied.
