Effect of Magnetically Treated Water on Precipitation of some Macro Elements in the Soil for Tomato Growth

This study was conducted to determine effect of magnetically treated water (MTW) on the precipitation of some macro elements in the soil for tomato growth. Magnetic flux densities used for treating the water were 124, 319 and 719 gauss (G) produced from electromagnet with direct current. A 1.0 litre of MTW was added to sandy loam in a bucket at 3 days interval for 45 days. Each treatment was replicated 3 times and a control experiment in which the soil was treated with 1.0 litre of non–magnetically treated water (NMTW) and replicated 3 times. The mean concentrations of calcium, potassium, sodium, nitrogen, phosphorus, organic matter and organic carbon for MTW treated using 719 G were 3.16 cmol/kg, 2.67 cmol/kg, 1.58 cmol/kg, 0.97 %, 2.39 mg/kg, 2.41 % and 1.39 %, respectively while the corresponding values for NMTW were 2.82 cmol/kg, 2.35 cmol/kg, 1.42 cmol/kg, 0.87 %, 2.26 mg/kg, 2.30 % and 1.32 %. MTW treated by 124 G also gave higher values of concentrations macro elements than the values from soil treated with NMTW. The influence of MTW by 124, 319, 719 G and NMTW on mean heights of tomato plant (growth) at 26 days after planting were 154.3, 178.6190.3 and 137.1 mm while at 47 days the heights were 560.0, 556.4, 588.6 and 469.3 mm, respectively. Mean diameter of the tomato stem at 30 mm above soil level for 124, 319, 719 G and NMTW at 49 days after planting were 8.64, 7.99, 8.21 and 6.96 mm, respectively.
