The approach of groove fastening sandy-loam and sandy soils of the Aral sea's drained bottom
Detailed description of the Approach
Aims / objectives: In Kyzylorda region, the area of the new heath land formed in results of drying of the Aral sea that makes more than 23000 km.sq. approximately half from wich sandy and sandy-loam soils on structure from these surfaces it is taken out a huge dust and salt masses to the nearest and remote territories what pollute the invironment and cause harm to health and an agriculture.
Methods: For prevention to deflation of light soils on wich separately worth trees and saxaul grow were cut sandy-accumulated grooves wich bacic direction was accepted with perpendicular prevailing winds. At grooves cutting it was used a cultivator with earthing working bodies (constr. -2,8PM) in the unit with a tractor (MT-80(82). The distance between grooves made 140 cent. It is width on top 30 cent in a bottom 15 cent depth 13 cent and height 10 cent. The term of groovers installation are July-August as by time of saxaul seed subsidence in them will be postponed the freshened sand which will serve in the beginning as a box and then as a mulching material for seeds from postponed in grooves seeds there is a self-sowing saxaul which quality per 1 ha in the first year makes up to 2500 pieces. The next years it is occurrence in grooves proceeds. Thus goes overgrowing with saxaul and other plants on the surface of sandy-loam and sandy soils, what prevents the deflationary processes. The applied approach allows to create bank of seed fund 'in-suty', with subsequent use of seedling for struggle against deflation.
