Abstract: The main purpose of this laboratory study is to indicate the variation in some characteristics of the sandy, sandy calcareous, and clay soil under the effect of the magnetically treated tab and/or salt water. Salt water (SW, 2000-ppm) was prepared by dissolving the sodium chloride (NaCl) salt in tap water TW (2 g L-1). Tab water and/or SW were magnetically treated by passage through a permanent electromagnetic field of 14٫000 G (1.4 Tesla) strength for 10 min, and then allowed to percolate through a soil column continuously for 2 h. Some characteristics of the studied soil samples were estimated after the infiltrate of the magnetically (M) and non-magnetically (NM) treated TW and/or SW. The MSW has decreased the hydraulic conductivity (HC, m day-1) by 41.1, 12.8, and 51.4% compared to NMSW for sandy, sandy calcareous, and clay soil, respectively. Magnetic induction may affect the coagulation of the fine particles to form larger aggregates. For clay soil, MTW decreased the sum of fine particles by 40.5%, while the MSW decreased it by 28.75%, which may be a dispersing effect of NaCl soluble salt. The Zeta potential ζ values were slightly shifted by SW and MSW. The calculated electrophoretic mobility (U) of the colloidal particles has increased under the effect of the SW by 15.6%, 28.6%, and 58.1% for the sandy, sandy calcareous, and clay soil, respectively. Magnetized water may affect the soil properties positively and/or negatively depending on the soil class and the application conditions.
