Особенности оценки запасов продуктивной влаги накапливаемой в гидроморфных серых лесных почвах для жизнедеятельности и продуктивности насаждений земляники

Actuality of recording level and pattern of gray forest soil moisture for strawberry production in Open joint stock Company “Plodopitomnik” in Nizegorod region has been substantiated. Supplying with water gray forest soils in this farm has been characterized. The farm is located on the territory near the interface of two forms of macrorelief: lower part of clops of interfluves and right (steep) bank of valley of the Volga River. The variations of physical characteristics (density of structure and water permeability) of hydromorphic gray forest soil, composing soil cove on slope plot of gully water reservoir located on slope of small river Valava (Volga tributary) have been shown. The effect of horizons crosspieces on gray forest soils overlapping and cutting off a significant part of water reserves from total reserves of productive moisture, accumulated in meter layers has been substantiated. Original scale is proposed for estimation of water reserves in above mentioned soils with revealing operative and potential unavailable reserves cut off by horizons crosspieces. The recommendations are given on cultivation of hydromorphic gray forest soils and for involvement of productive moisture reserves cut off by horizons crosspieces in rotation and diagnostics of these soils on accumulation of operative and other productive moisture reserves, recording moisture regimes of soils for making a decision on necessity of strawberry irrigation.
