THE ROLE OF RECEPTION IN AGROCHEMICAL reduced acid sod-podzolic soils Urals

At the soddy-podsolic soils in the Western Urals long-term field experiments examined the role of liming, organic, mineral (phosphate Form) fertilizers to reduce soil acidity. It is shown that periodic organic fertilizers for five crop rotation contributed to the decline of exchange acidity of the soil by 37%, the content of mobile Al - 38% compared with the option of no fertilizers. The use of phosphate fertilizers (in combination with potassium) has reduced the exchange acidity by 23%, the content of mobile Al - 22%. A significant role in reducing soil acidity, cations associated high acidity, high concentrations of absorbed bases, maintaining a positive balance of calcium in the soil belongs to liming. To resolve this issue in the conduct of liming acid soils require state support.
