The influence of species composition of grasses on the content of macroelements and fodder units in pasture feed

The research objective was studying the influence of specific structure on the content of macroelements and feed units in pasture sterns from perennial cereals and legumes. As the objects of the research perennial cereals and legumes and their mixtures served in different percentage ratios from the norm of seeding recommended for a forest-steppe zone. The indicator of hydrothermal coefficient of 2014 corresponded to sufficient moistening, 2016 - insufficient, in 2015 - moderate. The content of calcium depended on the cycle of grazing, weather conditions of the years of the research, grasses species and increased from the first cycle of grazing to the third. Pasture grass mixture surpassed control, i.e. Festuca rubra in the content of calcium for 0.85-2.29 %. The content of phosphorus and magnesium in solid pasture feed depended on weather conditions of the years of the research and grazing cycle. The content of phosphorus decreased from the first cycle of grazing to the third: 0...
