Sažetak
Vineyards soil degradation is a global problem, especially due to the intensive practices such as frequent tillage. Several studies about the impact of vineyard management and season on soil properties and hydrological responses have been carried out in the Mediterranean region. A few studies have been carried out in other climate types. The objective of this work is to study the impacts of tilled and grass cover management on soil properties and hydrological response. The results show that Bulk density (BD), soil organic mater (SOM) and available phosphorous (P2O5) were significantly affected by treatment and time x treatment, while water holding capacity (WHC), soil water content (SWC), mean weight diameter (MWD), and water-stable aggregates (WSA) were significantly different between time, treatment, and time x treatment. BD, SOM, and P2O5 were significantly higher in grass covered plots than in the tilled ones. WHC was significantly higher in tilled plots compared to grass covered. The opposite was observed in SWC, MWD, and WSA. WHC and WSA were significantly lower in the wet period, while the contrary was identified in SWC and MWD. Time to ponding (PT), time to runoff (RT), sediment concentration (SC), sediment loss (SL), carbon loss (C loss), and P2O5 loss had significant differences in time, season, and time x season. PT and RT were higher in the tilled plot in the dry season, occurring the opposite in the wet one. SC, SL, C loss, and P2O5 loss were significantly higher in the tilled plot than in the grass covered one. Run, SC, SL, C loss, and P2O5 loss were significantly lower in the dry period. BD, MWD, WSA, SOM, and P2O5, (high in grass covered plots) were negatively associated with SC, SL, C loss, and P2O5 loss (high in tilled plots). The large amounts of sediment and nutrient transport occurred in the tilled area in the wet season. More sustainable practices are needed to decrease soil degradation and reverse this process.
