THE MANAGEMENT OF SOIL AND WATER FOR DATE PALM EL-HADJIRA REGION, DAIRA OF TOUGGOURT (SOUTH OF ALGERIA)
In a hyperarid area, date palm requires an appropriated management. El-Hadjira region belongs to the saharan bioclimat floor. The mean temperatures are of 10.12°C (January) to 34.0°C (summer), the corresponding absolute values are -3.45 and 48.75°C. The thermal amplitudes are high and extremely brutal, rainfall is deficient and badly distributed. However, water resources are the fundamental element to improve production. Violence and frequency of wind determine the character of the desert region. The depth and organic matter soils are low, against, hydraulic conductivity and salinity are high. Monthly water requirements of date palm range from 49.6 to 240.6 mm. Flux density deficit in peak months is 7.8 mm day-1. The electrical conductivity (EC, 25°C) and sodium adsorption ratio (SAR) class irrigation water in the C4-S2 category. Requirements water of leaching salts are 276.0 mm in peak month. The techniques of surface irrigation and drainage water leaching salts from the soil associated with agricultural practices are reasoned for spatial and temporal management environment. The objective is to reduce the constrained effects of date palm production by efficient use of natural resources in a sustainable development context.
