Sažetak
Aim of this research was to determine the impact of diff erent soil management practices in apple orchard on Cambisol, on a slope (14°) in Marija Magdalena (Croatia). Four treatments were studied: tilled, barley straw mulched (3.5 t ha-1), corn stark mulched (3.5 t ha-1), and permanent grass cover. Investigation was conducted through three seasons (Spring, Summer, and Fall). Each treatment consists of 10 plots, where rainfall simulations and soil samplings were conducted to determine runoff , soil loss (SL), and soil physical properties. In Spring the results showed no signifi cant diff erences for bulk density (BD), soil water content (SWC), and mean weight diameter (MWD) between treatments. Time to ponding (PT) and time to runoff (RT) were signifi cantly higher on the barley straw (279 sec, 720 sec) and corn stark (125.5 sec, 720 sec) mulch treatments compared to tilled and grass cover (88.5 sec, 726 sec ; 70 sec, 396 sec) treatment. Signifi cantly higher infi ltration rate (IR) and lower SL was recorded on the mulched treatment when compared to tilled one. In Summer, there was an increase of BD when compared to Spring period on the tilled (1.3 g cm-3) and mulched treatments (1.2 g cm-3 ; 1.2 g cm-3), while the grass covered treatment had lower values (1.1 g cm-3). Overland fl ow was not created on all treatments in Summer period. In Fall there was a decrease of SWC on all treatment when compared to Spring and Summer period. Generation of overland fl ow was only noted on the tilled treatment. Signifi cantly higher values of PT, RT and IR was noted on tilled treatment during Fall, when compared to Spring period. However, SL was signifi cantly higher in Fall then in Spring (189%). Presented results show that application of barley straw mulch, corn stark mulch, and use of permanent grass cover are eff ective nature-based solutions to prevent the land degradation in apple orchards.
