Sažetak
The aim of this paper is to show the application of farmyard manure (FYM) and slurry in grassland forage production. Manures provide organic matter (OM) and plant nutrients to grasslands. On the other hand, inappropriate manure application decreases the efficiency of nutrient utilization with negative effects on the environment. The annual application of 20-50 t FYM or 28-110 m3 of slurry ha-1 increases grassland productivity and improves forage quality. However, since the amount of manure application is limited to a maximum of 170 kg N ha-1 per year, a smaller amount of nutrients is provided by with manure application on grassland, and the difference required for the planned yield, in the conventional agriculture, is applied with individual or complex mineral fertilizers. From the aspect of the manure efficiency the main periods of FYM application during the growing season are spring and summer. While the choice of application method is limited when applying FYM, the application of slurry using one of the alternative methods ensures lower nutrients loss and greater efficiency of nutrient utilization.
