This study was initiated to (1) develop a potentiometric procedure of using ion-selective electrodes (ISEs) to determine soil exchangeable potassium (K) in soil suspensions, (2) compare and improve the ISE methods of determining soil potassium Q/I relationships, and (3) characterize the effects of experimental procedures and other factors on the potentiometrically determined Q/I relationships for soil K;It was established that batch treatments of 5-g samples of Iowa soils in 100 ml 0.5 M BaCl[subscript]2 solutions for 1 hr and subsequent determinations of the extracted K in the BaCl[subscript]2-soil suspensions with K-ISEs in electrochemical cells that did or did not include liquid junctions can yield exchangeable K[superscript]+ results th...
