Effect of Magnetic Treatment of Irrigation Ground water on Soil salinity, Nutrients, Water Productivity and Yield Fruit Trees at Sandy Soil

Abstract

THIS APPLIED experiment was conducted at private farm (160 feddans), sustained of soil and water salinity, at km80 of cairo-alexandria desert road (the green wealth farms). four electromagnetic devise (6 inch) set up on the main sources of ground irrigation. one well for each agriculture sector apricot, peach, flame-seedless grape and thompson seedless grape sectors. these sectors has been irrigated by magnetic treated water (mtw), beginning of december2013, through a drip system.The results indicated that mtw has led to non-significant decrease of water salinity (only from 2.183.31-to 2.14-3.12 dsm-1), ph (from 8.2-8.3 to 8.258.15-), sar (from 6.47.7-to 5.6-6.0) and hypothetical nacl (from 57.37 -60.53% to 53.31-58.15%)Concerning the effect of mtw on soil chemical properties, the data showed that soil salinity was decreased after using mtw compared with the normal water. soil salinity was decreased from 4.88-6.15 dsm-1to 2.734.15-dsm-1 and 1.452.83-dsm-1 after one month and eight ones of the magnetic treatment, respectively. besides, ph values were reduced from 8.28.3-to 7.9-8.05 before and after magnetic treatment respectively. as well as the hypothetical nacl and mgcl2 were diminished from 21.5 meq/l and 8.0 meq/l to 6.3 and 3.0 meq/l through eight months from the treatment. it is worth mentioning that the magnetic irrigation had good effects on the availability of npk and micronutrients (fe, zn, cu and mn) all during fertilization season, entail the observed increasing on the yield of fruits. thus, the results indicated that the main beneficial of using mtw were in improving yield for apricot, peach, flame-seedless grape and thompson seedless grape to 40.0, 29.0 28.0 and 19.0 % respectively. also, raising the efficiency of water productivity to 40.2, 29.2,28.0 and 19.3. %, respectively.

Effect of Magnetic Treatment of Water or Seeds on Germination and Productivity of Tomato Plants under Salinity Stress

“…Other studies have shown that magnetic treatment improved the quantity and quality of sunflowers [14]. Irrigation with magnetically-treated water improved the productivity of various crops such as apricot (Prunus armeniaca), peach (Prunus persica), flame seedless grape (Vitis vinifera), and Thompson seedless grape (Vitis vinifera) as compared to those irrigated with untreated water [15].…”

Effect of magnetic saline irrigation water and soil amendments on growth and productivity of Kalamata olive cultivar

“…These results are in harmony with those obtained by, Mohammed et al, (2010) who demonstrated that there are numerous advantages to plant growth resulted from using of natural organic and inorganic products like magnetic iron which improved soil structure, improving water holding capacity and cation exchangeable capacity, and improving crop nutrition from macro and micro nutrients and finally the soil become more energy and vigor. It is worth to mention that the magnetic irrigation gave great impacts on the availability of NPK and micro-nutrients (Fe, Mn, Zn and Cu) all during fertilization season of Apricot, Peach, Flame and Thompson seedless Grape (Fanous et al, 2017).…”

The response of saline irrigation water to magnetization and its effect on soil properties and cowpea productivity in newly reclaimed lands in North Sinai

“…Significant response in the soil chemical properties (pH, EC, Na + , Cl -, SAR, available nitrogen, phosphorus and potassium contents) because of irrigation with the magnetized saline water compared to the normal water (Abd-Elrahman and Osama, 2017). Also, irrigation with magnetic treated water considered as a one of valuable modern technologies that improve crop production and alleviate salinity of soil and water (Fanous et al, 2017). Magnetized water technology may refer to technique can improve of both crops yield and save irrigation water .…”
