Application of merus ring and magnet with intermittent and continuous leaching of cations from saline soil using water from different sources

In many parts of the world today, water and soil resources are threatened with salinization. Extensive research has been done to desalinate water and soil resources. One of the solutions is soil leaching. To assess different methods of saline soil leaching, an experiment was performed in a randomized complete block design with three factors and three replications. Water type treatments include: magnetic water, water passing through merus ring and ordinary water as the main factor and two sub-treatments which are the salinity of water including saline water with electrical conductivity of 2.5 dS/m, fresh water with electrical conductivity of 1 dS/m, and saline-fresh water, in fact, the combination of saline and fresh water and leaching method (permanent and intermittent flooding) were in a total of 54 soil columns gathered from an olive orchard in Roudbar city. The results showed that the magnet treatment compared to the control was able to increase the yield of saline water to the level of leaching with saline-fresh water in the alternating method. The merus ring treatment performed better, as it was able to increase the yield of saline water in the leachate to the level of fresh water in the alternating method, by releasing more salt than the magnet.
