NATURAL ENOUGH MAGNESIUM IN SOIL STAVROPOL HEIGHT AT DIFFERENT LEVELS IN AGRICULTURAL LANDSCAPES AGROGENNOGO IMPACT
Held differentiated assessment of the natural resources of magnesium on the basis of the analysis of its contents in size fractions of different sizes agrochernozemov bayrachnye steppe Stavropol Upland an example polygon «agrarian landscapes.» The effect of the systematic application of different doses of complete fertilizer on MgO in reserves in soils of different landscape supplies. Soils are characterized by a high polygon, typical chernozems natural resources of the total magnesium - 1615-3475 mg/100g most severe soil humus and bottom of the slope differ significantly from the edge of watershed soil and the top of the slope on both the content of the gross magnesium and its distribution by category of reserves. From the use of mineral fertilizers of significant changes in the behavior of the various categories of reserves of magnesium in soil taxa for all landscape of seven years did not happen. However, there is a danger of further strengthening begin the process of destruction of minerals due to soil acidification by high doses of fertilizers, which may contribute to the depletion of natural stocks of batteries in soils.
