DYNAMICS OF PHOSPHOROUS SUPPLY OF ARABLE SOILS AND GRASSLAND IN BELARUS

Abstract

The results of Agrochemical Soil Survey for 2001-2016 showed the decline of mobile phosphate supply of arable soils and grassland in several regions of Belarus. The needs for improvement of P-fertilizer supply of potentially fertile Luvisol clay and loam soils are evident, as well as reduce the P-supply of poorer sandy soils with higher phosphate content. Differentiated norms of P-balance accordingly of initial phosphate content of different textured soils are proposed.
