Leasing of nutrients from soils: economic aspect

Abstract

The article presents the results of long-term lysimetric studies (for 1981–2020) on the influx of atmospheric precipitation onto the surface of the most common soils of the Republic of Belarus, their migration and transformation in soil solutions, the loss of nutrients (total nitrogen, nitrate and ammonium, phosphorus (P2O5) and potassium – K2O) from a soil layer of 1.0–1.5 m into the environment when used in crop rotations when cultivating agricultural crops of standard and new forms of fertilizers in optimal and increased doses, as well as standard fertilizers under a monoculture of perennial legume-cereal grass mixtures, with an assessment their economic damage in the system «аtmospheric precipitation – soil – fertilizer – plant».
