SALTS REDISTRIBUTION IN SOILS IRRIGATED WITH DIFFERENT WATER QUALITIES

Abstract

The current study aims mainly at investigating the impacts of using different water qualities for intermittent leaching of some soils on the redistribution of soluble salts and ions in these soils. Effects of the same qualities of water on the redistribution of soluble salts were reexamined after being magnetized. Also studying the effect of using magnetized water on seed germination, seedling emergence was a matter of concern within this study. Fulfilling the purposes of this study required collecting three soil samples namely, a clayey (alluvial) soil ofEC 2.3 dSm-1, a sandy clay loam (calcareous) soil ofEC 11.0 dSm-1 and a sandy (noncalcareous) of EC 4.4 dSm-1 . Columns were packed uniformly with either of the investigated soils and underwent experimental work. This work involved a leaching trial through which soil columns were intermittently leached using different sequences of different poor water qualities alternatively with the tap water. At the end of the leaching process, each soil column was separated into 3 equal segments i.e. 0-15, 15-30 and 30-45 em and chemically analyzed to monitor the redistribution of soluble salts as well as the ionic composition of the soluble salts within the different depths of the investigated soils.
