Effects of Magnetized Water on Soil Sulphate Ions in Trickle Irrigation

摘要

To reclaim soil and water, and to reduce soil salinity, magnetized water can be used. Magnetized water is obtained by passing of water through the permanent magnets or through the electro magnets installed in/on a feed pipeline. To investigate the effects of magnetized water and irrigation water salinity on sulphate ions of soil a field trickle irrigation experiment with complete randomized block design was performed at Gorgan Agricultural and Natural Resources Research Center, Gorgan province, Iran. The results showed that at all soil depths below the emitter, the mean soil sulphate ions for the magnetized irrigation water treatment are less than the non-magnetized irrigation water treatment and the differences were significant at 5% level. For the magnetized irrigation water treatment, soil sulphate ions decreased on average up to 37.3% (p<0.01). The use of magnetized water to reduce soil sulphate ions in order to reclaim salt affected soils is recommended for trickle irrigation.
