Abstract:
Magnetic force has been used in different field of science it offers many benefits. Now days, magnetic device use in agriculture is getting increased for field experience of better crop growth and development with the magnetized water without much scientific evidence. In this regard, a laboratory experiment was conducted for assessing effect of magnetism on chemical properties of saline water. Water with different salinity levels viz. S1 (0.5 dS m-1), S2 (2.0 dS m-1), S3 (4.0 dS m-1), S4 (6.0 dS m-1 and S5 (8.0 dS m-1) were exposed to magnetic strength viz. 0.18 Tesla (T), 0.29 T and 0.44 T under the south pole and north pole orientations over varied duration viz. two minutes, four minutes and six minutes. The electrical conductivities of saline water decreased significantly with increase of magnetic field strength and duration of exposure but the effects size were in reverse trend including for water salinity. The significantly and relatively high reduction of saline waters electrical conductivity value was recorded under the South Pole orientations. The 0.44 T magnetic field for six minutes exposure of saline waters recorded high EC decline which was 54 %, 31 % and 17.6 % respectively in the 0.5 dS m-1, 2 dS m-1 and 4.0 dS m-1 saline waters. The persistency of magnetic effect for saline waters found to be differed significantly for magnetic orientation. The low saline water up to 2 dS m-1 had the high persistency period of 5 days in South Pole while it was two days under North Pole. Moreover, the 4.0 dS m-1 saline water had two days more persistency under South Pole. The magnetic field did not bring any significant changes on saline water pH, cationic and anionic concentration. The magnetic field can be effectively used for bringing significant change in the electrical conductivity properties of saline waters up to 4 dS m-1. However, further research on magnetic field based water structural modification derived memory lasting and the magnetized saline water interaction with soils and eventually the crop performance need to be investigated.
