Abstract
The aim of this study was to investigate the impact of magnetization of fresh and saline irrigation water on bulk density, porosity , mean weight diameter and soil resistance to penetration and water holding capacity at different moisture tension in three samples of calcareous and gypsiferous soils and on the growth of corn . Plastic pots were filled with soil materials then 10 seeds of corn were planted in each pot , and reduced to one plant/ pot during spring and Autumn 2006 . The experiment was performed using completely randomized design (CRD). The plants were irrigated with four types of irrigation waters (fresh water, magnetized fresh water, saline water, magnetized saline water). The Value of electrical conductivity (EC) of these types of water were (0.76 , 0.72 , 4.45 , 4.40) ds.m-1 respectively during the experiment period after depleting about 50 % of the quantity of the available water . The results show that the soil irrigated with magnetized fresh and saline water increased the values of porosity, mean weight diameter , and water holding capacity and decreased the values of bulk density and penetration resistance in both season which affected the growth of shoots and roots of the corn . At the end of experiment of the spring and autumn seasons in first and second calcareous soils ,the values of weight of the vegetative growth were (16.96 and 16.83)gm (13.20 and 4.25)gm respectively . While for the gypsiferous soil the last values were (13.73 and 14.76) gm and (9.48 and 12.36) . The values of the weight of roots in the first and second calcareous soil were ( 9.44 and 9.12) gm (7.16 and 7.20) gm respectively . In the gypsiferous soil the values of the weight of roots were (8.35 and 7.07) gm (6.02 and 6.64 ) gm for each pot respectively compared with the pots which were irrigated with fresh and saline irrigation water . It may concluded that magnetization of fresh and saline irrigation water have a clear positive effects on some of the physical properties of the soil and therefore on some of corn plants parameters grown in these soils .
