Abstract
With increase in municipal and industrial water demand, reclamation of graywater and brackish groundwater become attractive as alternative irrigation water sources. However, irrigation with degraded water often destroys soil structure and reduces water infiltration with a deleterious impact on crop yields. This paper presents preliminary results from a soil column experiment with treatment of water types and soil amendments. Graywater and brackish groundwater were used in this study. Soil amendments included no amendment, 2% organic mulch, and 2% organic mulch plus 15% CaO of the organic mulch. The results indicate that graywater travels in a soil column more quickly than brackish groundwater. Soil conditioning delayed starting time of drainage and mass flow of water. In this study, soil conditioning enhanced the rate of water movement and water retention in columns.
