“…Endive and lettuce absorb and translocate selenium and mutagens from fly ash. Other food plants known to actively translocate chemicals include: cantaloupes, carrots, celery, coffee, green beans, herbai plants used for teas, mushrooms, peppers, radishes, rhubarb, and spinach (Shane et al, 1988).…”

“…However, some elements not injurious to growing plants may have accumulated in the plant dry matter to concentrations harmful to livestock that could potentially feed on the material (Gutenmann et al 1979, Shane et al 1988). However, at the application rates used in the present study, levels were not elevated above the natural abundance ranges expected for most soils.…”

Innovative methods are currently being sought to safely utilize and reduce the amount of sluiced fly ash stored in on-site facilities at thermal electric power facilities in Ontario, Canada. The objective of this study was to investigate the possibility of utilizing sluiced fly ash as a liming material on acidic soils. A greenhouse experiment was established to examine the influence of the ash on soil pH values and the yield and chemical composition of corn, soybeans, wheat and alfalfa grown on amended soil.The sluiced ash had an initial pH value of 9.1 (1:1 H 2 O) and contained an equivalent CACO 3 content of 11.5% (+0.2%) based on total content of Ca and Mg in the ash. Fly ash was applied at rates of up to 167 tonnes ha -1 to samples of the surface horizon (0-15 cm) of an acidic clay textured soil found local to the power plant. Application of fly ash increased soil pH values but a high concentration of boron in the added ash limited plant growth. Results indicated that the sluiced ash could be used as a liming material at application rates of up to 110 tonnes ha -1 , on acidic, clay textured soils provided boron tolerant crops such as alfalfa were grown. Further research is required to establish the potential for leaching of boron to ground water and to determine the potential for plant uptake of other trace elements such as As and Se.
