| Abstract | ||||
| This study aimed to Quantify the performance of magnetically treated Nile water, and saline water on plant growth, and nutrient content of Tomato, anddetermine the changes in soil properties due to irrigation with magnetically treated water.This study aimed mainly at investigating the effect of different irrigation water qualities on redistribution of soluble salts in soils due to intermittent leaching. It aimed also at studying effect of using these waters after being treated with recent magnetic technologies on seed germination, seedling emergence and redistribution of soluble salts in soils, to provide better soil water plant relation. To fulfill the objectives of this investigation three different soils were selected for conducting this study i.e. clay, calcareous and sandy soils under five types of irrigation water quite different in qualities i.e. tap water, three types of moderately saline water and one type of highly saline water. Tow laboratory experiments were conducted, the first and the second experiments were laboratory ones 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 the first experiment, effect of sequence of different water qualities on the redistribution of soluble salts and exchangeable ions in soil was examined. In the second experiment, effect of the previously mentioned water qualities after being magnetized, on redistribution of salts within the different depths of soil columns was also under taken. A greenhouse experiment was conducted to study the effect of magnetizing irrigation water on some chemical properties and plant dry weight yield. A germination experiment was conducted to clarify the effect of magnetizing the used waters on both germination percentage and rate. The obtained results reveal that, increasing salinity level of irrigation water gradually and significantly increased soil EC, Cl‑and SO42- concentration. The concentrations of soluble Ca2+, Mg2+, K+ and Na+ were sharply increased as salinity levels of irrigation water increased. Usage of magnetized waters resulted in percentages and rates of germination to increase at a high level of significance compared with the corresponding ones of the nonmagnetized (untreated) waters. Moreover magnetized water was shown to have two main effects, the first, increasing the leachability of soluble salts and the second, lowering soil sodicity. | ||||
