Summary

Between April 2014 and March 2015 farm-gate balances of phosphorus and potassium have been calculated on 82 Organic Farms. Results as follow: An additional fertilization with phosphorus, at least on the long run, seems to be
necessary to adjust negative phosphorus balances. Potassium also often shows negative balances, especially when leaching losses are considered. However, as long as the K-contents in the plants are high, additional potassium fertilization is not
necessary, especially when aspects of animal nutrition are considered.
