Physico-chemical properties of four artificial soils were monitored. The ability of soils to resist water erosion and efficient irrigation scheduling were also estimated. The studied soils were KS (Koka soil) which contains high value of organic matter, VS (Viva soil) made by poriferous pumice mainly, PP which is perlite in powder form and GP which is granular perlite. These soils had high percentage of sand particles with high value of hydraulic conductivity. The aggregate stability of VS was high with good structure for plant growth. Whereas, KS contained many nutrients and classified as a fertile soil. Soil erosion was not occurred when these soils were subjected to rainfall intensity of 40(mm/h). Moreover, when 30 years rainfall data was simulated for effective rainfall and net water requirement these soils were found to have high irrigation water efficiency. Generally, these artificial soils were expected to effectively resist water erosion and have high irrigation efficiency.
