Irrigation of perennial grasses sewage in the Southern Yemen

Abstract

The results of experimental studies on the impact of irrigation wastewater major cities of southern Yemen (Aden, Ibb, and Taiz) on soil properties and crop yield perennial grasses. For little-used irrigation mineralization waste water after their mechanical and biological treatment to ensure a high yield of perennial grasses in green mass reliably great, as compared with pure water from irrigation wells. In doing so, the negative impact of waste water on the properties of red-brown soils are not evident.
