[0] Manure fertilizers, intensity and import - CH Demeter Standards 2005 [2] EU Regulation 2092/91 does not limit the import of commercial fertilizers. It only limits the application of farm yard manure to 170kgN/ha. DEMETER does limit this application to the LSU equivalent that could be fed on the farms own fodder basis. DEMETER also limits the distance for transporting farm yard manure. [3] Own animal husbandry is an important factor in a farm organism as definied by DEMETER. The lack of own animals should not be underlined by importing manures: instead own animal husbandry should be established. Furthermore, imported fertilizers can only be applied if used in combination with composted or prepared animal fertilizers. [1] 
Imported organic farm yard manures may not exceed 50% of the quantity which is needed for the crops on farm. Commercial mineral and organic fertilizers are accepted but restricted according to their quality and origin and should undergo composting.
