Sažetak
U radu su prikazani rezultati analize sadržaja teških metala Cd, Cr, Ni i Pb u uzorcima neorganskih i organskih đubriva koja se nalaze na tržištu u Srbiji, a data je i početna procena količine teških metala koja se unose u zemljište prilikom upotrebe fosfatnih đubriva. Sadržaj teških metala u svim analiziranim neorganskim đubrivima je ispod MDK po važećem Pravilniku, a u uzorcima supstrata, koji se svrstavaju u organska đubriva, izmerena je povišena koncetracija Ni (2 uzorka) i Cr (1 uzorak). Prosečan (teorijski) unos teških metala u zemljište u Srbiji pod pretpostavkom da se godišnje po hektaru primeni 20 kg P2O5 niži je od evropskog proseka i blizak je podacima za Finsku i Dansku.
