THE RELATINSHIP BETWEEN THE VALUES OF ELECTRICAL CONDUCTIVITY OF DIFFERENT SUSPENSIONS AND SATURATED PASTE FOR DIFFERENT TEXTURED SOIL

Abstract

Laboratory study was conducted to determine the effect of texture soil and soil organic matter content of some central Iraq soils in the electrical conductivity of saturated paste extract values and filtrates soil stuck 1: 1 and 5: 1 water: soil. Find empirical relationship between the proportions of electrical conductivity values of saturated paste extract to the electrical conductivity values for the filtrates of soil stuck (conversion factor). The results showed that there is a polynomial of the first degree relationship of two variables conversion ratio of the water and into the soil coefficient, and these equations can be adopted in the calculation of the conversion of any soil stuck coefficient for the purpose of access to the electrical conductivity value of the saturated paste , as the study showed low electrical conductivity increase dilution with distilled water at the work of plankton, and increase the percentage of satisfying increasing the soil content of Clay.
