Abstract
Deep plowing reduced uptake of Sr85 by four irrigated crops on Pullman silty clay loam at Bushland, Texas. Uptake was further reduced when Na2CO3 was plowed under with the Sr85. The relative concentrations of Sr85 in mature soybean (Glycine max), sugar beet (Beta vulgaris), sudangrass (Sorghum sudanense), and cabbage (Brassica oleracea var capitata) plants grown with Sr85 applied in different treatments were: rotary tilled 20 cm deep, 100; plowed 90 cm deep, 25–50; plowed 90 cm deep with 22,400 kg/ha (10 tons/acre) of Na2CO3, 3–7. In the plowing treatments, 90% of both the Sr>85 and the Na2CO3 were banded in the furrow deeper than 75 cm. Crop yields were increased by deep plowing and were affected very little by the application of Na2CO3. This experiment demonstrates that a toxic chemical can be plowed under deeply with radioactive contamination to reduce the uptake of the radioactive material with little effect on yield from the chemical.
