Nutrient flow balance and efficient use of manure - lecture by Philipp Löw, Thünen Institute Braunschweig
Philipp Löw presented the new requirements for farmers regarding the application of nitrate and phosphate on agricultural land. In the course of the past few years, the pollution of the soil by nutrients has increasingly come into focus with regard to climate, air, water and nature conservation. Numerous regulations have been created which are valid throughout the EU and must be implemented in every member state. Philipp Löw described how these regulations are placing increasingly high demands on farmers and gave an overview of the current state of soil contamination. It was noticeable that especially in North-West Germany, significantly increased levels of phosphate and nitrogen in soil and groundwater can be observed. The measures now required by the regulations are expected lead to an improvement in soil quality and increased nature conservation through more effective use of nutrients. In the future, farmers will have to determine in a nutrient balance for their farms, monitor how much nutrients they apply and what yields they can achieve with them. Depending on farm management, conventional or organic, there will be surplus and limit values for nutrients that remain unused in the soil and possibly also in water bodies. In the second part of his presentation, Philipp Löw presented the study for Pellworm, which is being developed upon the initiative of “Ökologisch Wirtschaften”. Here, organic and conventional farmers will provide data from their farms, supported by data from all imported and exported inputs and outputs gathered by trading and transport companies so as to get a good data basis through limitations of the island situation. The study will also take into account the increasing wild gees population on Pellworm. Nationwide, nutrient balances will become obligatory for all farmers and thus the study of the Thuenen-Institute can provide an early opportunity for farmers on Pellworm to exchange knowledge and experience through cooperation and professional exchange.
