Abstract
Recent researches indicate that if water is exposed to intense magnetic field, it is possible to obtain many positive effects on water properties that improve water use in irrigation applications. The magnetized water is obtained by passing water through permanent magnets installed on a feed pipe line. Therefore, this work was carried out to investigate of irrigation by magnetic water and its effects on soil moisture distribution under ultra-low drip irrigation and dripper discharge. Three treatments of magnetic (0.325, 0.495 and 0 Tesla) was carried out by using three nominal drippers discharge of 0.5, 1.2 and 2.0 l/h under effect of different pressures of 50, 100, 150 and 200 kPa. The results indicated that the dripper discharge rate was increased by increasing the magnetic flux density at different dripper discharge rates and different operating pressures. Also, the moisture distribution pattern was increased horizontally more than vertically under dripper, by increasing the magnetic flux density at different operating pressures.
