Abstract
A study was conducted to evaluate the effect of irrigation with magnetic water and irrigation intervals on crust hardness, for two soils which contain different exchangeable sodium percentage . Soil samples were taken from the A-Horizon
( 0 -30 cm ) of two locations, one was non saline soil ( ESP = 4.48) and the other saline alkaline soil (ESP=21.14) from the experimental field of Agriculture College University of Baghdad , Abu Gharib. Both soils were within the topic torrifluvent group.The samples were treated with two types of water, ordinary water and magnetic water. Four periods of irrigation intervals included 2,4,6 and 8 days were adopted for all treatments.
The results showed that use of magnetic irrigation water reduced the surface crust hardness, and also to show a good ability to remove the negative effect of the exchangeable sodium percentage, on the structural properties of soil . The short irrigation intervals showed significant effect on decrease soil surface crust hardness
