Summary |
Research
is devoted to studying possibilities of saline collector-drainage
water use for irrigation in various soil-hydrogeological
conditions, recommendations development on this water use
in midstream of Syrdarya river. Hunger Steppe is the
biggest irrigated region in Syrdarya midstream. Climate
is sharply continental. Soils-bright sierozems; structure-light
and medium loam. Salinity is light from surface, medium
on depth of 60-100cm and with high gypsum concentration
on depth of 80-140cm. There are two plots of 20ha each in
state farm 16 and in farm 1-10 fields 5x5m. It is found,
that under irrigation with water which salinity is higher
than 2.5g/l soil properties are getting worse. Scientific
grounding is given of saline drainage water usefor irrigation
with minimal risk for soil productivity and environment
on example of Hunger steppe. |
