Economical Value of Irrigation with Wastewater Instead of Agronomical Water at Iran

To investigate the beneficial impacts of wastewater on agricultural economics by analysis of soil properties, we conducted an experiment in the lysimeter by measuring certain features essentially related to soil characteristics. Our objectives in this study were (i) the wastewater infiltration by soil and (ii) the effect of wastewater on soil properties. In this experiment, we had 9 lysimeter that 1, 2 and 3 lysimeters irrigated by domestic wastewater. Then, primary drainage water accumulated from these lysimeters and 4, 5 and 6 lysimeters irrigated by primary drainage water. In order to comparison soil properties, 7, 8 and 9 lysimeters irrigated by agronomical water and finally, soil and water properties analyzed in each stage. The results showed that soil could treating the wastewater and reduced BOD5 and COD of wastewater sorely. Also, irrigation w ith wastewater increased nutritive elements in soil that can be source of nutrition for plants. Our findings may give applicable advice to commercial farmers and agricultural researchers for management and proper use of water.
