The total amount of nitrogen fertilizer that may be used on the farm is related to the farms own capacity to produce animal manure. It must not exceed 1.4 manure units/ha (equivalent to 112 kg N/ha and 98 kg P2O5/ha). Market gardens with a high nitrogen export are allowed to use up to 170 kg N/ha after approval. (DI production standards, 3.2.1. Amount of manure)


According to the DI standards the nitrogen input allowed in general is lower than the one allowed by the EU Regulation 2092/91 (170 kg N/ha).


The farm production should be based on the individual (natural and cultural) conditions of the site. It should not depend on the input of nutrients from elsewhere. This aspect refers to the principle of a circular flow economic system of organic farming and to the biodynamic principle of the individuality of a farm.
