Can Magnetic water do something for us?
Objectives1. Conduct research to assess the performance of the tested crops under magnetized brackish and treated waste
waters.
2. Evaluate the quality of magnetically treated crops.
3. Examine the performance of magnetically treated potable water and saline water on plant growth, yield and
produce nutrient composition of selected plant types.
4. Quantify water productivity and water saving potential of magnetically treated irrigation water.
5. Improve water use efficiency.
6. Determine the changes in soil properties and pipes scaling due to irrigation with magnetically treated water
from different sources.
7. Understand the impact of salinity levels on magnetically treated water.
8. Evaluate the effect of magnetic technology on elements availability in the soils.
9. Study the response of different parts of plants to irrigation with magnetic water compared to plants irrigated
with ordinary water.
10. Understand the impact of magnetic technology to soil microorganisms and plant diseases and future uses for
bioremediation.
11. Investigate the effect of heat stress in plant growth treated with/out magnetic device.
