After 19-22 years of the monoculture no deterioration of physical and chemical properties of soil was observed (decreased soil compaction, an increase in pH and organic carbon content), but weed infestation was three times greater. In the monoculture rye yielded 28.3 percent less grain than in crop rotation. Reduced soil tillage, in particular pre-sowing, caused environmental changes to on lesser extent. Shallowed pre-sowing tillage increased soil compaction and weed infestation, but pH of soil was slightly reduced. The highest yield in the monoculture which was 25.7 percent lower than in crop rotation, was observed after spraying the stubble with Reglone and next, reducing tillage to only one ploughing to a depth of 20 cm
