The effect of organic fertilizers on the grassland biomass
Popis výsledku v původním jazyce
The aim of this study was to assess the effects of organic fertilizers (cow manure + dung water, slurry) applied in different annual doses of nitrogen (54 kg/ha; 84 kg/ha; 120 kg/ha) according to 3 different intensities of grassland utilization (extensive – 2 cuts per year, medium intensive – 3 cuts per year, intensive – 4 cuts per year) on percentage of plant functional groups (grasses, legumes, forbs), dry matter yield, and forage quality. The study was performed as a small-plot trial over 7 years on moderately moist grassland in the Czech Republic. The proportion of legumes was significantly higher in the fertilization treatments with cow manure + dung-water combined with medium intensive utilization and intensive utilization. Fertilization significantly increased dry matter yields compared to unfertilized controls. Extensive grassland utilization significantly decreased the energy value. Our findings suggest that medium intensive and intensive grassland utilization using organic fertilization which correspond to annual doses of nitrogen of 84 kg/ha and 120 kg/ha, are the most suitable for animal nutrition.
