I have read that passing saline irrigation water through a magnetic field reduces salinity effects. Some companies that produce those magnetic rings claim the same. When I asked for explanation, nobody could provide it. So, If anyone tried these rings in the field can share his/her experience with me, I will appreciate it.
Yes it is very much true, magnetic field neutralizes the effect of salinity...
yes it is true and now a days using magnetic water treatment the irrigation process are done for agricultural growth
though this treatment process salinity can be reduced.
Yes, but if the magnetic water devices are installed properly. Their effect lasts to a certain distance (which varies depending on the device and manufacturer). In addition, the device must be installed away from an electrical source so its magnetic field is not interrupted.
This still needs additional field research, because on one farm planting onions indicated that there was no difference in yield when they use the magnetic water device. So it's still questionable.
The application of a magnetic field on water decreases the hydration of salt ions and colloids, having a positive effect on salt solubility, accelerated coagulation and salt crystallization.
In an attempt with wheat (i forgot the crop), in National Salinity Research Center of Iran, it did not produce any positive results.
Thank you all for your responses.
I was thinking about this issue because I believe (if it has an effect) it depends on the strength of the magnetic field, the delivery pathway (metal, plastic, or an open channel) and the distance between the magnetic field and the plants.
- Still one more question, how long does this effect last? minutes, few hours, days....???? Does temperature has an effect??
probably these are the reasons for the variability in the results obtained by different researchers.
Yes. In our study it lasted for approximately 4 days and more (108 hours). But as pointed out it varies with teh strength of the magnetic field, pipe diameter, circulation speed etc. Temperature also influences it.
As magnetic field is affected by many environmental factors such as temperature and surrounded metal objects, I think the effect of this field on irrigation water will vary so much from one site to another and the lasting effect will also vary.

It does not. It prevents deposit of salts. So the treated water will leach the upper soil profile and will deposit all salts in the deep soils. But on the long run all soil profiles will be full of salt. It only delays the problem it does not solve it.
i did an experiment and found that the magnetic field affects the ideal dose of alum needed for water coagulation, as it had a negative effect on the coagulation process. Experiments are still ongoing to find out its effect on salinity, but initially it reduced the electrical conductivity of water
