INFLUENCE OF NEW FORMS OF LIQUID AND SOLID MINERAL FERTILIZERS ON PRODUCTIVITY AND QUALITY INDICATORS OF CEREAL, LEGUME-CEREAL GRASS MIXTURES AND ALFALFA ON SOD-PODZOLIC SOILS

Abstract

The article presents data on the effect of new forms of liquid nitrogen-potassium and solid fertilizers on productivity and quality indicators of perennial grass mixtures and lucerne in the cultivation on sod-podzolic loamy soils of the Minsk and Vitebsk regions and sod-podzolic sandy loam soil of the Minsk region. The positive effect of liquid nitrogen-potassium fertilizers has been established when used for the first and second grass mowings of the first, second and third year of use against the background of the introduction of phosphate fertilizers (cereal and legume-cereal grass mixtures) and complex fertilizers (lucerne), ensuring an increase in productivity and improvement of hay quality.
