This chapter presents the findings of long-term field experiments that investigated the erosion-protective capability of different crop rotations on slopes of various inclinations (2-5°, 5-10°, and 10-14°) in the Zemaiciai upland, Lithuania, since 1982. The mean water erosion rate under the field crop rotation varied from 9.9 t ha-1 yr-1 to 32.2 t ha-1 yr-1, according to the average results of 18 years of investigations. The lowest losses were under the grass-grain crop rotation, and they increased from 2.5 t ha-1 yr-1 on the slope of 2-5° to 7.2-7.4 t ha-1 yr-1 on the slope of 10-14°. The above-mentioned losses, as well as losses from the grain-grass crop rotation on a slope of 2-5° (7.5 t ha-1 yr-1), could be considered as environmentally friendly.
