The fertilizers which can be brought into a biodynamic farm are regulated in the chapter 3.2.2. and by a positive list in the appendix 4. Certain products (such as synthetic nitrogen sources, Chilean Nitrate, water soluble phosphate fertilizers, pure potassium salts and potassium salts with a chloride content exceeding 3%, municipal composts, sewage sludge, animal manure from intensive animal husbandry systems) are explicitly excluded from use. Others (such as natural phosphate rock, ground basic slag, potassium magnesium sulphate, magnesium sulphate, sulphur, trace elements) can only be applied if the necessity has been demonstrated and after approval. Animal manure should be prepared with the biodynamic preparations. The use of brought in fertilizers must be precisely documented. (DI production standards, 3.2.2. Brought in manures and soils; DI production standards, appendix 4)


The list of allowed fertilizers is shorter in DI standard than the EU Regulation 2092/91, i.e. conventional manure from poultry farming, liquid or semi-liquid conventional manures, meal from blood, meat and bone, pure potassium salts and potassium salts with a chloride content of larger than 3% are totally prohibited.


The fertilization shall be done as far as possible with the farms own resources, and therefore the import of fertilizers is restricted. Contamination with harmful substances must be excluded.
