Sažetak
The field experiment with NPK-fertilization rates was conducted on acid soil in spring 2008 as follows: a) 103 N + 52 P2O5+ 52 K2O b) 133 N + 182 P2O5+ 182 K2O ; c) 183 N + 312 P2O5 + 312 K2O. Each treatment plot measured 1008 m2and it was divided in four 252 m2 sub-plots (replicates). Winter wheat (cultivar Renata) was sown in the growing season 2010/2011. Grain yields of wheat were as follows: 7.44 t ha-1 (a), 8.74 t ha-1 (b) and 8.43 t ha-1 (c). As affected by the highest fertilizer rate, significantly were increased concentrations in wheat grain of P for 11%, Mg for 20%, Zn for 15%, Mn for 34%, Fe for 33%, B for 34%, Cd for 75%, and Sr for 67%. Cd concentrations were acceptable with aspects of human health (wheat grain: below 0.2 mg Cd kg-1).
