Essay

Meadow lands. To determine the effect of systematic mineral fertilizer application on the soil fertility and productivity of sown cereal grass stand and to establish their optimal quantitative variables. The research methods are generally accepted. The regularities of meadow agrocenosis formation under conditions of antropogenic influence are revtaled and optimum main nutrient and mineral fertilizer dose relations are fixed. The recommendations on meadow land fertilization are developed. The scientific developments are applied into production over an area 300 ha at the farms of the Kyiv region. The application of the developments secured the increase of land productivity 3.2-3.8 -fold. Agriculture.
