Source Protection Region (SPR) represents water sources, which includes lakes, rivers and underground aquifers protection, from overuse and contamination. In majority of European countries and also in Slovenia SPR contains four vulnerable areas; wellhead protection area (WHPA), intake protection zone (IPZ), significant groundwater recharge area (SGRA) and highly vulnerable area (HVA. SPR is usually a part of agricultural landscape, thus the water quality might is often affected by the agricultural practices, thus the Water Act regulate or limit conventional farming, especially the way of soil tillage, fertilization and pesticide application. For this reason, in many IPZ and SGRA zones the conservation tillage (CT) is allowed as the only soil tillage. In this article, CT systems, comprising minimum mechanical soil disturbance as well as no-tillage on organic died out or live mulch as a soil cover, which enables the best protection against water erosion, as well as nutrition and plant protection leakage.
F.01 Acquisition of new practical knowledge, information and skills
COBISS.SI-ID: 4426796The effects of biodiversity and management on grassland yield and soil C storage are expected to interact with climate and other pedoclimatic factors. Models combining plant trait composition with climate and management have been proposed to predict net primary productivity. The Agrodiversity experiment shows that it is possible to provide common standard guidelines for managing biodiversity adapted to local species, ecosystems, and agricultural practices. More research is needed to confirm that those guidelines can be applied also for grazed ecosystems across the wide pedoclimatic variability in Europe.
F.30 Professional assessment of the situation
COBISS.SI-ID: 4472364Selected case studies have shown that the economic results of conservation processing can be even better when achieving the same level of yield than conventional treatment. Although these are mainly higher purchasing machines, which is reflected in a higher depreciation cost, the savings at the same level of crops in the case in question, for most crops, move the balance in the direction of conserving treatment. Assuming the same level of yield and the energy savings achieved in relation to the results of the tested crops, we can expect a slightly better economic result in conserving treatment. The direction in which the financial instrument is overturned in the event of a fall in crops in conservation production is highly dependent on the parity ratios of fuel, machinery, labor and product prices. In the world The criterion shows that the decrease in crop prices encourages the increase in the share of areas under conserving production. When interpreting the results, certain caution is required and consideration should be given to the fact that ratios can be altered for the benefit of conventional soil treatment, in the event of crop differences in favor of conventional treatment. We must also point out, that in our case there is a single-criterion analysis which takes into account only the yield and costs, but does not take into account long-term benefits (eg conservation of organs, reduction of erosion) and weaknesses (more difficult to fight weeds, variability of the crop). Such analyzes would require multi-criteria analysis and long-term production monitoring, including soil monitoring.
