The effect and the after-effect of the ameliorative norms of urban sewage sludge (USS) in combination with a zeolite-containing agro-ore on the moisture regime, the reserves of productive moisture and the productivity of grain-pasture crop rotation are shown. It was established that the effect and aftereffect of the reclamation norms of USS in combination with zeolite-containing agro-ore increased humidity in the arable horizon by 3.2-5.1%. Urban sewage sludge in combination with the zeolitecontaining agro-ore had the maximum effect on the accumulation of productive moisture in the meadow black soil due to precipitation during the cold period of the year. The maximum productivity of grain-pasture crop rotation was marked against the background of the effect and the after-effect of USS in combination with a zeolite-containing agro-ore (51.7-73.6%).
