Abstract The experiment was designed to investigate both the rate at which Sr/sup 90/ moves down the soil profile under natural conditions and the manner in which the absorption of Sr/sup 90/ by plants changes with time, either as a result of penetration in the soil or because of chemical changes over long periods. The ratio of Sr/sup 90/ to calcium in the grass grown on all soils decreased by approximately 20 to 30% for the four growing seasous. The availability of Sr/sup 90/ which had been incorporated in the soils for 3 1/2 years was compared with that of Sr/sup 89/ which was freshly added to the soil. Tabulated results show that the amount of freshly added Sr/sup 89/ which became equilibrated with the calcium chloride solution ranged from 26.5 to 55.5% in soil samples. The corresponding values for Sr/sup 90/ were some 3 to 10% lower. This difference was significant for most soil samp1es. (B.O.G.)
