| Abstract |
This study aimed mainly at investigating the effect of different irrigation water qualities magnetically treated on plant growth and nutrient content of tomato and determine the changes in soil properties due to irrigation with magnetically treated water to provide better soil water plant relation. It aimed also at studying effect of different irrigation water qualities on redistribution of soluble salts in calcareous soil due to intermittent leaching using these waters after being treated with recent magnetic technologies. To fulfill the objectives of this investigation three types of irrigation water quite different in qualities were selected for conducting this study i.e. fresh water, well water (moderately saline water) and drainage water (highly saline water). Two experiments were conducted; the first laboratory experiment by using soil columns subjected to intermittent leaching with different water qualities applied at volume equal to 1.50 times the soil water saturation capacity. In this experiment, effect of different water qualities on the redistribution of soluble salts in soil was examined and also effect of the previously mentioned water qualities after being magnetized, on redistribution of salts within the different depths of soil columns was also undertaken. The second field experiment was conducted during the season of 2011 on a calcareous soil at Abou-Masooud village Alexandria Governorate, Egypt to study the effect of magnetizing irrigation water on plant growth and nutrient content of tomato plants and determine the changes in some chemical soil properties. A magnetic unit for water treatment (magnetron) was installed to flow out magnetized water through magnetic field compared with untreated water.
The obtained results reveal that, the improvement in plant growth parameters reflected in yield per plant was increased until the treatment of 2383 ppm magnetic water. There were significant increases in plant growth and some chemical contents of tomato plant. The results of the current study demonstrated that magnetic treatments improved dry weights of tomato plant compared to control. Magnetic treated water also enhances nutrient mobility in soil, increases uptake of NPK by plants to improve tomato yield productivity. The results obtained also concluded that; the electrical conductivity of the soil was decreased with using magnetic saline water in irrigated soils, removal of excess soluble salts and dissolving slightly soluble components such as phosphates, carbonates and sulfates. The use of magnetic techniques with low quality water is very important for irrigation without any expected problems in the soils and plant
