Thermodynamic Potassium In Iraqi ‎Soils, Ahmed Al-Zubaidi, Shatha Al-Rubaie

Jerash for Research and Studies Journal مجلة جرش للبحوث والدراسات

In order to characterize the status and behavior of potassium in Iraqi soils thermodynamically, ‎twenty eight surface soil samples were collected from different locations to represent the ‎most dominant soil groups in Itrg (put thin names) Chemical, physical and mineralogical ‎characteristics were determined. The potassium forms of soluble, exchangeable, non - ‎exchangeable, mineral and elemental were determined. Thermodynamic parameters related ‎to potassium such as ionic strength, activity coefficient of potassium, activity ratio (K⁺: Ca^{2 +} + ‎Mg^{2 +}) and the free energy of replacement (DF) of K⁺: Ca² + mg²⁺ were …
