Sr90 Uptake by Plants as Influenced by Soil Types and Liming1

A greenhouse study was conducted to determine the influence of various soil types and liming on the uptake of Sr90 by plants. There were highly significant differences in the total uptake and concentration of Sr90 by corn, soybeans, buckwheat, Sudangrass, and alfalfa from different soil types and liming. In general, the total uptake of Sr90 from acid Ashtabula, Miami, and Canfield soils was considerably higher than the total uptake from slightly acid Brookston soil. Liming depressed the total uptake of Sr90 by the plants grown on the acid Ashtabula, Miami, and Canfield soils; but had no effect on the total Sr90 uptake by the plants from Brookston soil. These differences appear to be associated partly with the differences in exchangeable calcium and pH of the soils. The accumulation of radiostrontium by the various plant species after 5 weeks of growth was in the order: Buckwheat > soybeans > alfalfa > Sudangrass = corn.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
