Agronomic factor affecting polonium-210 and lead-210 levels in tobacco. I. Soil and fertilizer
Journal Article
·
· Agron. J.; (United States)
An examination of soils from tobacco-producing areas and fertilizers commercially available for tobacco production revealed that a wide variation in the levels of Ra/sup 226/, Pb/sup 210/, and Po/sup 210/ exists in those samples. Cultural practices and source of fertilizer may contribute to these variations. Radioelements from fertilizer used for one growing season may not affect the level of these elements in the immediate crop, but will contribute to the buildup of the radioisotope level in the soil.
