8.4.2 How to apply
§ 2 Principles of Fertilizer Application
(1) Substances according to § 1 Nos. 1 to 5 may only be applied in accordance with good professional practice. Fertilization according to good professional practice serves to supply plants with necessary nutrients as well as to maintain and promote soil fertility, in particular to ensure the population's supply with high-quality, reasonably priced products.
(2) Good professional practice includes that fertilization is aligned in terms of type, quantity, and timing with the requirements of the plants and the soil, taking into account the nutrients and organic matter available in the soil as well as the site-specific and cultivation conditions. The nutrient requirement of the plants is determined by their yield potential under the respective site- specific and cultivation conditions as well as the quality requirements for the products.
(3) The Federal Ministry of Consumer Protection, Food and Agriculture (the Federal Ministry) is authorized, in agreement with the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, and with the consent of the Federal Council, to specify in more detail by means of a statutory ordinance:
  • the principles of good professional practice as defined in paragraph 2,
  • area-based upper limits for the application of nutrients from farmyard manures of animal origin.
