Briefly explained
Farm manure According to the definition in the Fertilizer Act, farm manure includes substances that are produced during animal husbandry in agriculture (e.g. solid manure, liquid manure and slurry) as well as plant substances that are produced or generated during plant production or agriculture. Farm manure is a valuable natural fertilizer. However, their nutrient content varies considerably. It is therefore important to know the exact macro- and micronutrient content in order to ensure that fertilizers are applied in line with requirements and the environment. The chemical-analytical examination of farm fertilizers is carried out according to the VDLUFA and DIN examination methods. |
Legal requirements Fertilizers are generally subject to the requirements of the German Fertilizer Ordinance (DüMV). Among other things, it specifies the essential material properties of fertilizers and defines source materials. The Fertilizer Ordinance (DüMV and EC 2003/2003) regulates the use of substances in accordance with the Fertilizer Ordinance (DüV) on agricultural land. It serves to protect water from contamination by nitrate from agricultural sources (Nitrates Directive). The DüV defines the so-called good professional practice for the application of fertilizers according to type, quantity and time. |
