THE ROLE OF MONOVALENT IONS IN THE DETERIORATION OF SOME PHYSICAL PROPERTIES OF CALCAREOUS SOILS IN NORTHERN IRAQ by Saja Albarzanjy, Mohamed Al-Obaidi, Hazim Ahmed

“…The flow of electrolyte solution through the columns led to increasing additions of mono cations (K+) that negatively affected the deterioration of different soil groups by sliding their colloids from the original aggregate, causing dispersion of clay colloids dominated by montmorillonite mineral with high ability to swell and disperse clay particles and sliding organic materials, which led to a decrease in the weighted diameter index from 6.18 to 5.43 mm, which led to the deterioration of the soil and a decrease in its water conductivity for all soils from 3.39 to 1.61 cm.h-1. we suggest that the effect of potassium should be taken into account in evaluating soil structure.…”
