The results of 20 years studies of the Institute for Land Reclamation on drainage efficiency and cultivation of sod-gley-connected sandy loam soil in the Poozerye Lake area of the Republic of Belarus showed that these activities create more favorable conditions for the growth and development of plants. They contribute to the productivity of crop rotation by 59.7%, longstanding of cultural hay-by 12.8%. More than half of the regions melioration systems were in service for more than 30 years and the state of the water regime of reclaimed land need to be improved. In such cases, it was necessary to carry out agro-ameliorative actions on reclaimed farmlands in order to drain the excess water on the surface layer of soil and crops, as well as to increase subsurface runoff and create additional reserves of available moisture in the subsurface layer, and other measures aimed at improving the productivity of reclaimed land. It was important that was necessary to keep the moisture on upper relief elements by making slits across the slope. It increased the productivity of green mass of corn at 105 cwt, (20.2%) and spring wheat by 5,6 cwt./ha (14.0%). Making of agro-ameliorative actions was most effective in the background to optimize the agrochemical properties of soil by fertilizing of full demand.
