The Management Of Soil And Water For Date Palm In Hyper-arid Region (south Algeria)
Authors : Chennafi Houria .
Abstract
El-Hadjira region belongs to Saharan bioclimatic floor. The thermal amplitudes are high and extremely brutal; rainfall is deficient and badly distributed. Violence and frequency of wind determine the character of the desert region. The depth and organic matter soils are low. Against, it is distinguished by appreciated hydraulic conductivity and salinity. In peak month, the flux of deficit density was 7.8 mm.day-1. The irrigation water was ranged in the C4-S2 categories. The project feasibility is reasoned by an efficient use of soil and water resources to reducing the constrained effects of the date palm and intercrops productivity.
