Sažetak
Soil erosions by water and wind are a harmful phenomenon on agricultural soils, which appearance has been increasing rapidly in Europe in recent decades, primarily due to increased climate variations and changes in types of grown crops. This study presents research results that have been obtained on the erosional experimental fi eld near Daruvar during two periods which are characterized as extraordinary in terms of precipitation conditions. The aim of this paper is to determine soil erosion by water on variants with diff erent tillage methods in extremely rainy 2010 when double crop (wheat and soybean) was grown and extremely dry 2012 when maize was grown on the experimental fi eld. Experimental fi eld consists of six diff erent variants: I variant - the control treatment - black fallow, II variant - ploughing up and down the slope to 30 cm depth, III variant – notillage, IV variant - ploughing across the slope to 30 cm depth, V variant - very deep ploughing across the slope to 50 cm depth, VI variant - ploughing to 30 cm depth + subsoiling to 50 cm depth across the slope. In the period October 2009 to August 2010, normal to extreme monthly precipitation amounts were recorded and soil losses were relatively small. The second experiment period from November 2011 to September 2012 was prevailingly dry, but with higher 30-minutes rates and soil losses were extremely high. It follows that heavy short-term rainfall has stronger infl uence on erosion than total precipitation during the studied periods and that vegetation (crops) and applied tillage methods had signifi cant infl uence on preventing erosion processes. This indicates that the impact of extreme precipitation events can be mitigated by appropriate agro-technical tillage methods, which can specially fi nd its application in a changing climate.
