2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Technology of creation of meliorative plantings for struggle against wind and water erosion

2.2 Detailed description of the Technology

Description:

In Syrdarya river’s delta on alluvial drought sandy and loam sand soils processes of wind and water erosion become more active with a view of protection of the soils it is applied covering fascine made from a local cane or reed. Fascines thickness 12-15 cm settle down on a surface by lines in a 2-3 m. On distance of 20 centimeters it is carried out planting of a saxaul seedlings
-Planting of the saplings was done in holes and uninterrupted furrows, which were formed by hands.
-Depth of holes and furrows is 20-25 cm.
-Distance between holes was 1.5-2 m.
-Furrows were perpendicular to the prevailing winds (west-east) and placing mould in several optio0ns: 1- moulds on both sides; 2- the same from the southern side of a furrow; 3- the same from the northern side. Furrows alternated with holes rows.
-Length of rows variants in repetition was 100 m.
-Saplings were filled up by hands in rows in 1-2 meters, distance between rows was 2-2.5 meters.
Prevention of water and wind erosion on sandy and loamy sand soils of the Syrdarya delta.
Many farmers use the given technology for prevention of wind and water erosion on the lands.
The technology is applied on the area of 1.5 sq.km. Expenses per 1 ha make 99.2 $ USA or 14880 tenge.
Irrevocable water consumption in agricultural land use in the Syrdarya delta, development of the areas of irrigation, livestock grazing led to the contradiction between the agricultural industry and the ecological state of the region. It caused more intense processes of desertification, among them are soil salification and increase in the groundwater mineralization: degradation of vegetation cover; erosion and soil deflation; wind-blowing of the salts from dried bed of the Aral Sea; sand advance on the arable land, etc. At present about of 60% of irrigated areas within the Syrdarya delta are strongly salificated.
