On a quantitative level shows the leading role of the agro physical factors in the formation of fertility of moist soil. To evaluate the role of drainage, reclamation loosening and plowing on the crests in increasing the fertility of sod-podzolic gley light loamy soil were used complex indices agrochemical and agrophysical cultivation. Draining increased indicators agrophysical index of sod-podzolic gley light loamy soil with 0,31 to 0,58, and additional agroreclamation processing techniques - to 0,80-0,86. Soil on their agrophysical condition under the influence of drainage moved from weakly tame in the average tame group, and the application of agroreclamation techniques - in the well tame group ofsoils. Modern systems of reproduction of soil fertility on moist soils should include a set of activities aimed at regulating the water-air regime of soils and improving their agro physical properties, including their drainage using engineering systems and the use of highly efficient agro-reclamation techniques that are adapted to the soil-reclamation conditions humid agricultural landscapes.
