Tillage erosion under different tillage systems
Erosional drift was recorded during the nine-year investigation cycle (1994-2003.) on Stagnic Luvisol, in central Croatia, under common agricultural crops grown in 6 tillage treatments. This work presents the results relating to the total erosional drift, with special reference to the time of occurrence of erosional drifts per USLE crop development stages of the crops grown. The largest erosion in the 9-year period was recorded in the standard variant (black fallow). This was followed by the variant involving conventional up and down the slope ploughing. Erosional drift was much smaller in no-tillage variant and treatments with ploughing across the slope. Much higher erosional drifts were recorded in the growing of spring crops (maize, soybean) than in winter crops (wheat, oil seed rape). Also, in the growing of crops, notably spring crops, erosional drifts were not evenly distributed during crop growing, quite the contrary. The period of seedbed preparation, or the period immediately after sowing spring crops, is the most critical period with the highest risk of erosion. In the growing of spring crops, this is the period when over 80 % of the overall annual erosional drift occurs in all tillage treatments. In the growing of winter crops, crops of high density, no critical periods were observed. Summing up all the advantages and drawbacks of the studied tillage methods for a wide application in crop growing on this soil type, we recommend no-tillage and conventional ploughing across the slope.
