Influence of mineral fertilization and pasture management on forage quality
Original language description
The effects of different levels of grazing utilization and mineral fertilization on the grassland quality were studied in the locality of Rapotín during 2003-2010. The plots with area of 200 m2 were grazed rotationally by heifers from the suckler cows breeding system with three different intensities of grazing utilization (four-P4, three-P3 or two-P2 grazing periods per year). Each type of utilization was established in a treatment with or without application of mineral fertilizers N100P30K60 + (pure nutrients). The forage from extensively utilized pastures (effect of fertilization was insignificant) was characterised by a low energy value (NEL = 5.07 MJ.kg-1 DM for nil-fertilization; NEL = 4.95 MJ.kg-1 DM for NPK treatment). We further found out thatthe demand for energy supplements to balance the nutrient ratio in animals' feeding rations increased with the intensive grassland management with nitrogen fertilization (PDIN/PDIE = 1.29).
