Summary |
Study
is directed to setting soil moisture regime, irrigation
norm and depth perfection, soil salination dynamics and
ground water salinity under sprinkler irrigation
and permanent horizontal drainage, water-salt balance
preparation, crops yield definition. Soils-sierozem-meadow
and meadow; heavy and medium loam. Ground water salinity
is 8.5 g/l. Lands are leached after development. Irrigation
method-sprinklers. Crops-alfalfa, sugar beet. Plot area
is 14.6 ha. Drainage-subsurface with depth 3.5m. In result
of long-term investigations is found that sprinkler irrigation
on background of subsurface permanent drainage provides
stable soil salt regime within layers 0-1 and l-2m. Non-saline
and weakly saline soils prevailed, ground water salinity
decreased, load on drainage during growing period was 0.15-0.32
of irrigation norm, optimal pre-irrigation moisture was
recommended as 0.7-0.75 FFC. |
