Seventh sector is located on the right bank of the Euphrates River at the town of Abu-
Kamal, the Syrian-Iraq border, and its square 18140 hectares. Invest most heavily sector
too, where crops depend on irrigation, irrigation networks mediated cons
isting of earthen
trenches, canals and to pump water by pumps on the banks of the Euphrates.
Research aims to assess the pedelogical properties of agricultural soils by using laboratory
and field tests: leaching speed, permeability, density, porosity, water field capacity, natural
humidity (hygroscopic– wilt limit), so as to contribute in choosing optimal modalities for
irrigation and drainage, and rehabilitation Land affected by salinity and exited the
investment.
The soils of the sector are clay, clayey sand, fine sand, and it has low permeability, low
water field capacity because of sedimentary origin, and the total porosity is low in the
upper part of subsurface soil because of its impaction. There is a relationship between
hygroscopic moisture of soils and its structural composition. The search recommend to
agriculture Fabaceae crops with different roots deep to help improve soil building, and
need to use spray irrigation method to control the water quantity and wetting depth.
