The uptake of strontium was measured in 16 species and strains of forage plants grown in soils similar in texture and pH but varying in strontium and calcium content. Data are tabulated. Results indicate that every legume species takes up more strontium than any grass; within either the grasses or the legumes tested the variation of strontium content was not marked. The amount of strontium taken up was directly related to the amount of calcium taken up, and no major discrimination was found between strontium and calcium by either grasses or legumes. Neither the grasses nor the legunies showed the same order of strontium content for every soil. The results indicate that animals grazing mixed legume- grass herbage, where the legume amounts to a significant proportion of the forage, will ingest much more strontlum-90 than animals grazing all-grass pastures on equally contaminated soils. The significance of the findings is discussed in relation to the fall-out of strontium-90. (C.H.)
