Increasing of humus content as soil fertility and crops yield driver requires studies of the interactions between humic fertilizer rates and biomass productivity and quality. Thus, application of humic fertilizer would be purposeful considering relevance of natural forming of humus. This long and slow process could be improved by applying different produced organic fertilizers. Humic fertilizers Turbo Grass (TG) containing 7.8% humic, 1.9% fulvic acids and 19.5% K was applied to improve productivity and feeding value of grass in dairy farms. The objective was to evaluate the effectiveness and to determine optimal rate of humic fertilizers (up to 32 l ha-1) on grass chemical composition, yield, metabolisable energy (ME), netto energy (NEL) and digestibility of intensively managed sowed pastures along with different mineral fertilization. The applied TOPSIS method offered an analysis of changes in biomass indices under different mineral fertilizing background, namely different Turbo Grass rates. Nonetheless, rates of humic and complex fertilizers had different effects on recorded parameters and further studies are necessary to clarify impact patterns.
