Sažetak
Conservation tillage is a practice that, among others, acts upon erosion and soil physical properties. Soil erosion in turn is a process that affects degradation of soil fertility. There are different treatments that can decrease this process or reduce it to a minimum. This primarily applies to the crop grown, but also to conservation tillage in the broadest sense of the word, particularly if no mulching or at least partial leaving of plant residues on soil surface is practiced. Soil physical properties are in turn greatly influenced by various forms of conservation tillage. Still, highly divergent results have been recorded under different ecological conditions. The more rigorous the tillage operation, the higher is its disturbance of the existing soil physical status. In this way, particular components of soil physical fertility get changed in varying degrees. These issues are considered in the paper, with special reference to conservation tillage.
