| Popis: | The agrochemical state of sod-podzolic soils of thе Western Polissya is analysed area of next agro-industrial groups: 27b – sod-podzolic gley-dried clay-sandy, 14b – sod-podzolic and podzolic-sod gley clay-sandy soils; 5b – sod-podzolic and non-glued and gleyy clay-sandy soils on sandy sediments. The content of humus, alkaline hydrolyzed nitrogen, mobile phosphorus and exchangeable potassium in sod-podzolic soils on arable land, under pasture and hayfields has been investigated. Determination of agrochemical indexes of soils, conducted in the laboratory of analytical support of agrochemical and agro-ecological research and quality of products Rivne branch of the state institution “Institute of Soil Protection of Ukraine”. As a result, a low and medium degree of land provision was found for the studied parameters (with the exception of mobile forms of phosphorus in the agricultural group 14b under grass) irrespective of their agricultural use. In terms of humus content, agricultural production groups 14b and 5b under haymasters have an average degree of provision (2,1–2,2%), 27b for arable land and 5b for pasture ‒ low; on the content of alkali hydrolyzed nitrogen ‒ very low ( |
