Abstract

The effects and residual effects of farmyard manure (FYM), straw fertilization and mineral N fertilization were investigated in Field F of the long-term fertilization trial in Halle (Saale), Germany. With sufficient mineral N fertilization, FYM and straw did not directly yield. The application of FYM alone increased the yield of potato less than those of silage maize and sugar beet. With low mineral N fertilization, however, residual effects of FYM, applied to root crops, were observed in the following cereal crops. Application of more mineral N to root crops had the same residual effects. incase of omitted mineral N fertilization, the humus content of the soil decreased rapidly. This implies that almost no stable humic material had been accumulated by application of FYM and saw. The calculated N loss increased with enhanced organic fertilization. in case of mineral N fertilization thecontent of organic C (C-org) was slightly higher (1.4 to 1.5%) than without any N fertilization (1.3%). FYM and straw (with same amounts of dry matter) likewise enhanced the C-org-content and, consequently, the content of decomposable C (C-dec) In general, organic fertilizers should not be applied in too large amounts to avoid N losses.
