Study the Effect of Irrigation with Industrial Wastewater on Soil Chemical Properties (Case Study: Torbat-Heydarieh)
Due to the scarcity of water and the growing demand for water resources, the use of wastewater is necessary. Therefore, there are numerous regional investigations in the field of wastewater use and the effect of irrigation with it is of great importance. In this study, the effect of industrial waste water on the chemical properties of soil under cultivation of barley in Torbat-Heydarieh was studied. For this purpose, a factorial experiment with a randomized complete block design with four replications (R) was carried out in a field experiment. The treatments in this study were three treatments: well water (T1), sugar plant wastewater (T2), water and wastewater (87.5% water and 12.5% wastewater) (T3) combination with two full irrigation levels (L1) and 75% water stress (L2). The results showed that water stress and type of irrigation water had a significant effect on potassium, phosphorus, total nitrogen and salinity at 1% probability level and on acidity at 5% probability level. The highest amount of potassium, phosphorus, total nitrogen, salinity and acidity in T2L2 treatment, the lowest amount of potassium, phosphorus and total nitrogen in T3L1 treatment and the lowest acidity in T2L1 treatment with 7.2 was observed. The overall result of the research is that the irrigation with the sugarcane factory sewage in a water stress condition not only has no adverse effects on the chemical properties of the soils of the studied areas, but because of the positive effects, it is recommended to irrigate the barley grazing area with this water resource.
