Economically optimal N‐fertilization as influenced by location, preceding crop, cultivation of soil, phosphatic and potassic fertilization and choice of variety. – The economically optimal quantity of N‐fertilization is mainly influenced by location, preceding crop, cultivation of soil, phosphatic and potassic fertilization and choice of variety. The optimal organization of these factors, however, to the extent that it can be influenced by the farmer, is a precondition of an effective N‐fertilization. – Depending on the above‐mentioned factors the economically optimal quantity of N‐fertilization shows a great variation. In the majority of cases the optimal N‐quantity to winter wheat ranges between 100 and 180 kg/ha and to sugar beets between 120 and 200 kg/ha.
