Increase of soil fertility and productivity of forest planting material in the forest nursery “Ak kayyn” of the Republic of Kazakhstan

The article analyzes the mechanical and physical and chemical properties of soils in the forest nursery “Ak kayyn” of the Republic of Kazakhstan. It was established that dark chestnut saline soils occupy 25 % of nursery territory. To grow the planting stock on these soils with modern agrotechnics is rather problematic even with the use of mineral fertilizers. The cause of low suitability of dark chestnut saline soils is ability to form crust. Cracks are formed in dry seasons as a result of shrinkage. These cracks are filled with surface horizon substances. When the soil is moistened the cracks are compressed and “excess material” in the lower part of the profile creates pressure causing displacement of soil blocks, and forming a sliding surface and microrelief “chillegay”. As a result of these instigations it was established that introduction of ameliorants can ensure the elimination of soil crust on dark chestnut soils. Optimum results during model experiments were obtained with simultaneous application of phosphogypsum and ash on the basis of 20 and 10 t/ha accordingly.
