EFFECT OF FERTILIZERS ON HEAVY METAL RESIDUES IN AGRICULTURAL SOILS

Abstract

The use of fertilizers is an integral part of agricultural production nowadays, as it has beneficial effects on the yield of agricultural products and the functioning of the agricultural sector. Nevertheless, their unregulated use can lead to serious harmful effects on the environment and human health. The aim of this research is to measure the residual amounts of selected elements in agricultural soils, aggregated due to the use of fertilizers during the vegetation season and to predict the potential for contamination of agricultural soils. The applied dose of fertilizers has resulted in the accumulation of heavy metals in the soil, but their quantities were within the allowed threshold values.

Primena đubriva je u današnje vreme sastavni deo proizvodnje jer unapređuje poljoprivredni sektor i prinos gajenih biljaka. Međutim, njihova nekontrolisana primena može dovesti do ozbiljnih štetnih efekata na životnu sredinu i zdravlje ljudi. Cilj ovog istraživanja je bio da se izmere zaostale količine pojedinih elemenata u zemljištu usled primene đubriva tokom vegetacije useva i da se na osnovu toga predvidi mogućnost zagađenja poljoprivrednog zemljišta. Primenjena doza đubriva je uticala na akumulaciju metala u zemljištu i njihov sadržaj je bio u graničnim vrednostima.
