Soil that contained thirty parts per million of arsenic and a soil of similar type containing eight parts per million were transferred to a greenhouse. Oats and cowpeas were planted and samples of roots and tops were obtained and analyzed. In all cases the concentration of arsenic in the tops and roots was appreciably higher in the plants grown on the high arsenic soil although the tops had much lower concentrations of arsenic than did the roots. Portions of the soil from the low arsenic soil were then spiked with additional calcium arsenate and planted to cowpeas. Marked differences in germination and rates of growth were apparent. The addition of large amounts of calcium arsenate to gray light sandy loam soils may be expected to interfere seriously, sooner or later with the subsequent growing of such arsenic sensitive crops such as cowpeas, oats, cotton, and various grasses. 1 table.
