The Effect of Technogenically Polluted Water of the Debed River on the Agrochemical Indicators of Soils and Plants Chemical Composition

Abstract

The studies have indicated that under the influence of technogenically polluted waters of the river Debed, the humus content in the soils decreased, the mechanical composition turned from heavy loamy into medium loamy and the reaction – from slightly alkaline to neutral and subacidic. The content of gross nutrients and the amount of absorbed cations decreased. The content of gross and mobile forms of heavy metals (HM) increased. The accumulation of HM (Cu, Pb, Mo) in vegetable crops exceeded the maximum allowable limits in many times and posed danger to human and animal health.
