Sažetak
Soil compaction issue is a growing limiting factor for agricultural production. Progress in technology and agriculture, launched a long-term trend of soil destruction as a result of compaction. The experiment placed on Stagnic Luvisols will try to provide an assessment of the impact of tillage system on soil compaction. The aim of this study was to determine the optimal tillage system due to the compaction of individual horizons. For that reason field experiment with six soil tillage systems was set up in Central Croatia. Tillage systems differed in tools that were used, depth and direction of tillage. During 2012 information of soil resistance, bulk density and soil porosity was collected. Statistical data evaluation showed significant differences in bulk density and porosity in most of the soil layers between all tillage systems. Bulk density values at all depths of all tillage systems varied in ranges of 1.47-1.69 g cm-3. Soil porosity showed significant difference between all tillage systems in surface and deepest soil layer. Values ranged between 38.18 and 47.19%. Soil resistance showed significant differences in most of the soil layers between all tillage systems. There were no significant differences in soil resistance between soil layers during dry (August) and wet (December) periods in layers up to 30 cm. It can be concluded that different tillage practice significantly affected soil resistance in most of the soil layers during the year, except in periods of the highest precipitation surplus and deficit.
