Abstract

Abstract Fluidized bed material (FBM), a dry, high-Ca, alkaline waste product from the combustion of coal and limestone, was used as the sole Ca source for ‘York Imperial’ apples ( Malus domestica Borkh.) grown in outdoor sand cultures for one season. Leaf Ca tended to increase with increasing rates of FBM and flesh Ca was not significantly increased by FBM application, although incidence of cork spot tended to be reduced. The trees showed no visible symptoms of toxicity or altered nutritional levels from the FBM treatments.
