Sažetak
In this paper, we report on the results of our investigation into the effects of different tillage, fertilization and previous crop on the chemical properties of loamy soil under spring barley and winter barley. We observed an increase of humus quality. More marked changes were in CT (r = 0.663, P < 0.05) than in RT (0.648, P < 0.05) and N fertilization (r = 0.678, P < 0.05) and SB (r = 0.761, P < 0.01) as well. A higher amount of TOC positively affected on parameters of soil sorptive complex in CT as well as in N and in SM treatments. A higher amount of TOC positively effected the portion
of Ca2+ under CT (r= 0.795, P < 0.05), but also increased exchangeable Na+ (r= 0.830, P < 0.05) and K+ (r= 0.881, P <
0.01) in RT and N treatments.
