In arid and semi‐arid regions, farmers use low quality groundwater because of limited availability of high quality irrigation water; instead, magnetized water can be used for irrigation given its better quality. Magnetized water is obtained by passing water through permanent magnets or through electro‐magnets installed in or on a feeding pipeline. This study at the Gorgan Agricultural and Natural Resources Research Center, Gorgan province, Iran, investigated soil moisture distribution from trickle irrigation. Treatments were magnetic and non‐magnetic water and sub‐treatments involved the addition of 200 mg/L calcium carbonate and 400 mg/L calcium carbonate with well water providing the control. The experiment was laid out with a complete randomized block design with three replications. Soil moisture around the drippers was measured for 1, 2 and 3 days after irrigation during the 3‐month irrigation period. The results show that the differences in soil moisture for days 1, 2 and 3 after irrigation with magnetized irrigation water were lesser than those for the non‐magnetized irrigation water treatments. Irrigation with magnetized irrigation water caused higher soil moisture compared with the non‐magnetized irrigation water for different irrigation water salinities. The use of magnetized water for irrigation is recommended to improve irrigation efficiency.
