An investigation of the factors influencing the diffusion of Rb/sup 86/ in eight soils showed that the more strongly Rb/sup 86/ was absorbed by the soils the slower was the rate of diffusion. In leached soils that were dried after labeling, diffusion was correlated with the amount of Rb/sup 86/ fixed against NH/ sub 4/OAc extraction. In leached soils that were kept moist after labeling, diffusion was closely related to clay content and exchange capacity. In dilute kaolinite systems, diffusion was related to the amount of Rb/sup 86/ in solution. (auth)
