Studies intended to modernize the crop rotations for increasing soil fertility, quality and yielding of produced crops. Perennial grasses and green manure crops were included into rotation at increased content of legumes in crop structure to reduce the intensity of nitrogen fertilization. In experiments on 3 six-field crop rotations the factors such as soil compaction and structure, weed infestation and crop yields were studied. Energetic efficiency of particular crop rotations per 1 ha arable land was given
