Environmental Impact of Magnetized Water: Evidence from Heavy Metals in the System Soil-Plant

Abstract

Capacity for agriculture production needs to be increased to meet the demands of the increasing human population. Within alternatives for an improvement in technology of agriculture in arid and sub arid countries’ irrigation with magnetized water (MH2O). This study was carried out to investigate the nutrients taken up by plants irrigated with (MH2O). During this study, we have grown Cucumis sativus in greenhouse for one month. The growth was carried on a sandy loamy soil type with two sets of pots 1) one set of pots without MH2O, as reference and 2) another set of pots was irrigated with MH2O. The results revealed that the plants’ leaves irrigated with MH2O were enriched in Zn, Cu and depleted in Ba, Ti and Sr relative to the plant grown in control conditions and unchanged in Fe, V, Ni; Mn and Cr. The roots of the same plants irrigated with MH2O were depleted in Fe, Mn, Ti, Ba, V, Ni, Cr, Zn and Sr. Translocation of elements from roots to leaves irrigated with MH2O seems more important than for plants irrigated with ordinary water. Based on the results of this study, irrigation with magnetized water may exhibit a positive effect on nutrition of plants. In addition to the effect of MH2O on growth, content of nutrients, revealed the effect on the quality of plants. These results show that irrigation with MH2O in arid countries with reduced water resources, may help to promote agriculture for an amelioration by increasing available elements.
