EFFECT OF MAGNETIC IRRIGATION WATER AND SOIL CONDITIONERS ON SANDY SOIL PROPERTIES UNDER SALINE STRESS CONDITIONS
Salinity is one of the most important threats to agriculture especially in Sinai. So, this study was carried in North Sinai for one season to evaluate the effects of Magnetite Iron soil conditioners with and without magnetic water irrigation on Date Palm tree under salt stress conditions. There is not much research carried out the combination effects of magnetic water and Magnetite Iron as a soil amendment to improve soil properties and crop yield under saline conditions at North Sinai, Egypt. The treatment of Magnetite or Magnetic Iron was 0, 300, 550 and 800 gm/tree with and without magnetic water irrigation. From the results, the best treatment was 800gm/tree magnetite iron with magnetic water which decrease EC, SAR and pH by 14 %, 5% and 2% consequently. On the other hand, it was improved soil properties such as OM and CEC as follow 29 % and 31% consequently. The macronutrient (N, P, and K) was increased by 40%, 14% and 7% consequently when compared with nonmagnetic water. Also, there was increased soil content of micronutrients (Zn, Mn, Fe, and Cu) as follow 20%, 12.5%, 22% and 17% consequently when compared with nonmagnetic water. In addition, it is consequently enhanced yield components compared with nonmagnetic water irrigation which increased by 60%.
