THE UPTAKE OF $sup 90$Sr BY RYEGRASS
It is shown that 20% of the "fall-out" Sr/sup 90/ deposited in rain can appear in the aerial parts of ryegrass growing during the period of deposition. It is considered that almost all this activity is taken up directly by the leaves, stems and surface roots and not by the roots in the soil. This suggests that rate of fall-out is the controlling factor in determining the Sr/sup 90/ content of grass. The "fall-out" Sr/sup 90/ in the three soils used in the experiment was not less available to the ryegrass than freshly added Sr/sup 85/, suggesting that the availability of Sr/sup 90/ does not decrease to any appreciable extent with time.
