Abstract

The LEACHING of POTASSIUM is affected by several factors such as soil texture, concentration of native POTASSIUM, amount and velocity of water in the soil and ADSORPTION COEFFICIENT. This study was performed for evaluating the effect of soil texture and concentration of native POTASSIUM on LEACHING of POTASSIUM in four soil series (Yeknabad, Ahmadabad, Pamas and Hasanabad). The native soil POTASSIUM was leached with 10mM of CaCl2 solution. Also, the adsorption isotherm was conducted for evaluating the relationships between the ADSORPTION COEFFICIENT and equilibrium concentration of K+ with the losses of POTASSIUM in soils. The results showed that after five and twenty pore volumes, the range of K+ leached from the soils were equal to 12-120 and 205-388 kg ha-1, respectively. The ADSORPTION COEFFICIENTs were in the range of 1.86-5.65 1kg-1. Using linear relationship between the LEACHING of K+ and the amount of leachate, the rates of POTASSIUM LEACHING were obtained to be in the range of 0.02 to 0.23 kg ha-l mm-l leachate.
