Sažetak
Our objectives were to quantify water erosion (referred to as soil loss) during a 14-year investigation period (1994-2008) on Stagnic Luvisols, in central Croatia, under common agricultural crops grown in six tillage treatments. This paper presents the results of research into the total soil loss, with special reference to the occurrence time of soil loss per crop and developmental stages of the crops grown in the investigation: Maize (Zea mays L.) ; Soybean (Glycine hyspida L.) ; Oilseed rape (Brassica napus var. oleifera L.) ; Winter wheat (Triticum aestivum L.) and Spring barley (Hordeum vulgare L.). The largest erosion in the 14-year period was recorded in the check treatment. Following was the variant that involved ploughing and sowing up and down the slope. Much lower soil losses were recorded in no-tillage treatments and treatments with ploughing and sowing across the slope. Much higher soil losses were recorded in spring growing seasons (row crops, maize and soybean) than in winter seasons (wheat, barley and oilseed rape). In spring row crops growing season soil losses were not evenly distributed, quite the contrary. The period of seedbed preparation, or the period immediately after sowing spring crops (the last decade of April, May and the first decade of June) was the most critical period with the highest risk of erosion. In spring crops growing season over 70% of the overall annual soil loss occurred in all tillage treatments. During the winter growing season (wheat, barley, oilseed rape - crops of high density), critical periods were not observed and water erosion was insignificant.
