Physical Benefits of Magnetized Water

1.  Salinity

Magnetic treatment of saline irrigation water can be used as an effective method for soil desalinization. 

The application of a magnetic field on water decreases the hydration of salt ions and colloids, having a positive effect on salt solubility, accelerated coagulation and salt crystallization.  Field experiments

conducted in Egypt showed that, sandy loam soil pots irrigated with normal highly saline water of an

electrical conductivity value of 8.2 mmohs/cm retained salts compared to pots irrigated with

magnetized saline water. The study showed that MW increased leaching of excess soluble salts,

lowered soil alkalinity and dissolved slightly soluble salts.

2.  pH

Joshi and Kamat  and Busch et al. have observed pH changes with the application of a magnetic

field to water.  Parsons et al. confirmed a decrease in pH in a study using sodium hydroxide to

stabilize pH at 8.5 then applying magnetic treatment to the solution.  In this study, the magnetically

treated water required up to 2.5 times more sodium hydroxide compared to the controls to stabilize

pH.  pH has been shown to decrease from 9.2 to 8.5 after magnetic treatment in a system with

Ca(OH)2 , where the degree of the reduction was dependent on the strength of the magnetic

treatment.  Busch et al.  showed an initial decrease in pH from 7.0 to 6.5, that was followed by an

increase in pH with time from 7.5 - 8.0.

3.  Permeability

Water becomes degassed in the process of being magnetized and this degassing increases soil

permeability, which creates an increase in irrigation efficiency (Bogatin et al., 1999).  In addition

to soil permeability, MW water interacts with the structural calcium in cell membranes, making the

cells more permeable (Goldsworthy et al., 1999).  The reduced surface tension observed in MW

results in better infiltration of water and a reduction in water and chemical use.  At the Indianapolis

500 Brickyard Crossing Golf Course a MTD has been installed to treat irrigation water.  An

improvement in the infiltration distribution of water has all but eliminated wet and dry area,

reducing 80 hours of weekly hand watering to less than 10 hours a week (Ritchie & Lehnen, 2001). 

The improvement in uniformity distribution of irrigation water has saved money in labor, hand watering

and roping off wet areas, and golf cart damage.
