Abstract
Water is becoming the most important limiting natural resource nowadays and more than 70% of water is being utilized for irrigation. Shortage of surface and underground water could be partially overcome by reuse or recycling of sewage water and its multiple uses are becoming more and more important to meet the increased demand of agricultural production. Poor water quality degrades soil quality, results in the accumulation of heavy metals and alteration of soil physical, physico-chemical and chemical properties and influences the soil health to a great extent. Studies by different authors on different soil properties, by the effect of domestic sewage irrigation on quality of soils, soil nutrient status, properties are reviewed in this paper.
Key words: Sewage water, soil properties, soil health, irrigation.
