| Summary: | Abstract The flood meadow was analyzed in the conditions of radioactive pollution of the territory to study the effect of mineral fertilizer on the efficiency of a meadow and 137 Cs content in green grass stand. The experiment was conducted in alluvial meadow sandy soil with 137 Cs pollution density of 559-867 kBq/m 2 in the subzone of soddy-podzolic soil of southern taiga of the Belarusian province of sod-podszolic slightly humic soils and low-land swamps. The study revealed that the efficiency of natural grass stand is low, the introduction of mineral fertilizer increased the productivity of green grass stand of a meadow to 37 t/hectare with nitrogen fertilizers being the main factors. The decrease of 137 Cs in green grass stand triggered the use of potash fertilizer. The use of a flood meadow as a pasture at 137 Cs pollution density of over 555 kBq/m 2 is impossible for livestock production satisfying norms on 137 Cs content in milk and meat without the use of mineral fertilizers. |
