摘要：The paper defines methods for the quantitative assessment of arable land structure by productivity, soil-protective ability and humus recovery balance. The dependence of quantitative indicators of arable land structure on the ratio of annual and perennial crops was established. The method of assessing the structure of arable land allows us to determine the optimal structure.
