Different aspects of special organic ameliorants application on reclaiming breaking grounds of light granulometric composition are considered. Optimization of complex properties of recultivated layer of sandy soil under the effect of a fertilizer- ameliorating composition appeared as more effective than that when using unmodified peat and manure on the background of mineral fertilizer application. Soil productivity in the year of ameliorants application has reached 4,0 -4,8 t / ha of fodder units with an efficiency payback of 1 ton of ameliorant equal 110-200 kg of green mass of vetch-oat mixture and getting 2,12 t / ha of barley grain in the aftereffect. A significant improvement in humus status, pH value, the content of mobile forms of nutrients in the recultivated soil were reg istered, as well as its biological activity, what has been confirmed in other series of experiments on soils of light granulometric composition
