Sažetak
Changes in climatic conditions in both possible directions - increase or decrease of annual precipitation and mean annual temperature, will actualize the issue of soil conservation by tillage. I order to estimate the effect of the current climatic conditions, soil loss was measured on Stagnic Luvisol of sloping terrain in the Daruvar area in six different tillage treatments and the following crop rotation: maize – soybean - winter wheat - oilseed rape – double crop (barley + soybean). The highest erosion in the 15-year period was recorded in the control treatment. Following was the treatment that involved ploughing and sowing up and down the slope. Lower soil losses were recorded in no-tillage treatments and treatments with ploughing and sowing across the slope. Higher soil losses were recorded in spring row crops growing (Maize and Soybean) than in winter crops (Wheat and Oilseed rape). In the current climatic conditions an average loss of 0.45 cm of the plough layer was recorded in the control treatment, which means that the entire plough layer be completely eroded away in a period of 57 years. In ploughing and sowing up and down the slope treatment average soil loss was 0.08 cm and plough layer would be completely eroded away in a period of approximately 300 years. In all other treatments which we recommend for the area of Stagnic Luvisol the soil could be preserved for the next several thousands of years. The primary goal of this investigation was to define the amount of soil that would be eroded under different tillage treatments in altered climatic conditions.
