Impact of using magnetic water on the micro structure of leached saline-sodic soil.

Structural changes in the porous media are critical in evaluating the soil pore system and other physical properties of leached soil. In this work, the combination of selected physical parameters such as bulk density and hydraulic conductivity with images of scanning electron microscopic (SEM) was used to study the impact of five levels (1, 3, 5, 7, and 9 magnets) of magnetically treated water (MTW) on the structural changes in pore spaces of leached high saline-sodic soil, compared with leached soil with non- magnetically treated water (NMTW) and unleached soil. Results show that leaching saline-sodic soil with MTW leads to a remarkable increase in soil pore network as confirmed by SEM observations and ImageJ software program.

Investigation on using magnetic water technology for leaching high saline-sodic soils.

One of the most important factors considered in leaching salt-affected soils is reducing the amount of water and leaching time particularly when magnetizing water is used. In this study, soil column experiments were conducted to assess the rate of salt removal and estimate the amount of water required for leaching in order to reduce salinity (EC) to ≤ 4 dS m and sodicity (ESP) to < 10. Soil samples with EC = 216 dS m and ESP = 82 were taken from Basrah City, Iraq, for the conduction of laboratory experiments, and these samples were subjected to magnetized water (MW) with magnetic fields of 1, 3, 5, 7, and 9; different exposure time; and constant flow velocity.
