Summary |
Study
is directed to soil desalination based on leaching with
regard for precipitation, drain design effectiveness
definition and imrovement. Climate is continental, dry.
Relief-weakly sloped plain. Soils-sierozem-meadow, loam,
saline, sulfate-chloride. Ground water depth is 0-2.0m and
salinity is 15-20g/l, sulfate-chloride. Subsurface drainage
specific extent is 37.8 m/ha, depth 3.5-4.0m. Plot is equipped
by measuring devices. In result of research main principles
of land desalination have been developed by means
of outstripping subsurface drainage construction taking
into account precipitation, reducing term of land development.
Subsurface drainage main parameters and design are recommended. |
