| الوصف: | 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+: Ca2 + + Mg2 +) and the free energy of replacement (DF) of K+: Ca2 + mg2+ were determined or calculated. The quantity - intensity curves of K+ were constructed, there the buffering capacity and labile pool K values were calculated from these curves. The results showed the studied soil sample differed in the thermodynamic parameter values in spite pf their similarity in the content of exchangeable potassium. The thermodynamic parameters were better expressing the supply power of potassium in comparison with the classical parameter exchangeable potassium probably due to differences in texture and mineralogical compositions. Based on the values of free energy and buffering capacity of potassium, the studied soils, were classified into different categories. It was concluded that the thermodynamic parameters can be successfully used to describe the statue and behavior of potassium in agricultural soils. Therefore it is recommended to use such parameters for soil potassium management for short and long terms of cropping |
