Relation Entre L’activité Biologique Et Le Comportement Hydro Physique Des Sols Dans Le Contexte Du Systéme Prairial Naturel Irrigué A L’eau Usée

Abstract

The practice of irrigation using wastewaters is a promising solution to alleviate the problem of water stress in semi-arid regions. Our study focuses on the impact of the practice of irrigation with wastewaters on both physical and biological components of soil; as well as the interactive effects of these two components on water functioning in soil of eastern Algeria. The water analysis showed high organic and fine-particle pollutions, but with no significant influence on soil properties. Our findings revealed positive effects of wastewater irrigation that increased the abundance of earthworm communities, soil porosity, water retention and hydraulic conductivity.
