Magnetic Treatment of Irrigation Water:  Experimental Results and Application Conditions

The effects of magnetic treatment on irrigation water have been studied. We showed that the main effects were the increase of the number of crystallization centers and the change of the free gas content. Both effects improve the quality of irrigation water. As an example, changes in natural water du...

Description
Summary:The effects of magnetic treatment on irrigation water have been studied. We showed that the main effects were the increase of the number of crystallization centers and the change of the free gas content. Both effects improve the quality of irrigation water. As an example, changes in natural water due to magnetic treatment in a commercially available apparatus, Magnalawn 2000, have been studied. On the basis of laboratory and field results, the type and the chemical content of natural water for which a magnetic treatment method is the most efficient have been determined. Our analysis shows that the important components for effective magnetic treatment are flow rate through the apparatus and certain chemical parameters of water, namely, carbonate water hardness of more than 50 mg/L and concentration of hydrogenous ions in water at pH > 7.2. Irrigation with magnetically treated water is the most effective for soils with high soda content.
