Abstract
Radioactive isotopes were used to follow the uptake by plants of trace quantities of the heavier alkali and alkaline earth ions applied to soils. The uptake of Sr and Ba was inversely proportional to the exchangeable soil Ca, and the uptake of Rb and Cs was inversely proportional to the available soil K. Distr. factors for uptake of the alkali ions were calculated as % of applied ion taken up/% of available K taken up. For the alkaline earth ions the denominator was the % of exchangeable Ca taken up. Distr. factors were: Rb, 1.0; Cs, 0.04; Sr, 0.4; and Ba, 0.02.Keywords
