The results of three-year studies have shown that annual pre-winter deep loosening of a loess slope had significantly decreased soil compaction as compared to ploughing. Significant differences in compaction remanied during the whole vegetation period and disappeared after harvest. Such a state of the soil had influenced raising tendencies in sugar beet and spring wheat yielding. Substituting winter ploughing with deep loosening has not had any considerable influence on the water reserves in soil or on investigated physical properties of soil.
