Sažetak
Our objectives were to quantify water erosion (referred as a runoff and soil loss) during the 16-year investigation cycle (1995-2011) on Stagnic Luvisols, in central Croatia, under common agricultural crops grown in six tillage treatments. This paper presents the results relating to the total soil loss, with special reference to the time occurrence of soil loss per crop and development stages of the crops grown: Maize ; Soybean ; Oil-seed rape ; Winter wheat and Spring barley. The largest erosion in the 16-year period was recorded in the standard treatment (black fallow). Following treatment was the treatment that involves ploughing up and down the slope. Much smaller soil losses were recorded in no-tillage and treatments with ploughing across the slope. Much higher soil losses were recorded in growing of the spring row crops (Maize and Soybean) than in the winter crops (Winter wheat, Spring barley and Oil-seed rape). In growing of spring row crops, soil losses were not evenly distributed during crop growing, quite contrary. The period of seedbed preparation, or the period immediately after sowing spring crops (May and first decade of June) is the most critical period with the highest risk of erosion. In the period of growing the spring crops over 80% of the overall annual soil loss occurs in all tillage treatments. The period from May to mid-June is the riskiest period for water erosion in the agroecological conditions of central Croatia if low-density spring row crops (Maize, Soybean, Potato, Tobacco, Sugar beet, Sunflower) are grown in the field. The trend of increasing participation of low-density spring crops compared to high-density winter and fodder crops on the arable areas in the Republic of Croatia indicates that the problem of water erosion on sloping terrains will be increasingly present. During the winter crops growing (wheat, barley, oil-seed rape) - crops of high density, no critical periods were observed and water erosion was insignificant. We are recommending some reduced tillage and ploughing across the slope due to the all advantages and drawbacks of studied tillage methods in 16 years investigation for a wide application in crop growing on this soil type.
