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.
