Influence of Arsenic Applied to the Growth Media on the Arsenic Content of Flue-Cured Tobacco1
- H. G. Small and
- C. B. McCants2
The concentration of As in the cured leaf of field-grown flue-cured tobacco varied from 2 ppm where no As was applied to the soil to 14.3 ppm where the rate of application was 48 pounds As per acre (288 pounds lead arsenate). The highest concentration was in leaves from plants grown on the sandier soils and decreased as the clay and iron content of the soil increased. The As content of the aerial portion was considerably lower than that of roots of plants grown in sand cultures containing soluble As.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
