Summary

The influence of different fertilization (NPK, PK, 0) and cutting frequency (2, 4 or 6 cuts) on dry matter yield, feeding value and plant composition of the sward of fen soil permanent grassland was investigated over five years. A randomizedblock design with plots was used, with three blocks. Effect of N application (NPK with 140 kg N/ha per year) was very low, because of a high N-mineralisation rate in the fen soil. Under intensive management (4 or 6 cuts) the PK-treatment (without N) reached a high feeding value as well as a high dry matter yield. This result may be very important for organic grassland farming on fen soils. Deficiencies in soil nutrients (0-treatment), especially potassium, reduce dry matter yield, high quality forage plants content of the sward and mineral content of the herbage.
