| To study the physiochemical behavior of potassium adsorption phenomenon in some agricultural expansion areas western of Iraq. Six locations were selected represented Al-Anbar governorate different mineral composition of clay fraction there are Al-Ramadi, Heet, Hadeti, Rawi, Ani and Al-Qami. One gram of dry soil for every location put in 100ml polyethalen tube then 30ml potassium solution with the concentrations 0, 20, 40, 80, 100, 120, 140, 160 and 180 mgK.L-1prepared from K2SO4 was added and shakes to equilibrium. Langmuir linear equation was used to characterize potassium reaction. The results showed the following: - 1- A higher adsorbed quantity of potassium was obtained in Heet soil ( 81.19 mg K.kg-1 soil), and Al-Ramadi, Rawi, Hadeti, Al-Qami with quantity 76.34,74.63, 72.16, 67.73 mg K.kg-1 soil respectively, while adsorption quantity was recorded at Ani soil ( 66.24 mgK.kg-1 soil). 2- The amount of adsorbed potassium was increased with increasing of potassium concentration in added solution. The difference in the soil properties (Soil texture, a mount of available potassium and soil content of CaCO3) have clear effect on potassium adsorption. | ||
