The results of investigations of farmyard manure (FYM) and mineral NPK fertilisers in a forage crop rotation are presented in this article. The experiment was carried out on a fluvoglacial soddy-podzolic sandy loam soil in LIA, Voke Branch in 1979-1996. The highest yield of feed units per ha was obtained after application of 104 t/ha of FYM every other year and mineral NPK fertiliszers every other year. Application of 52 t/ha of FYM annually strongly blocked a decline in soil pH and increased the sum of sorbed bases in the soil. Both fertilisers increased the content of available P2O2 and K2O in the soil as well as the content of humus
