Effects of applied sewage sludge compost and fluidized bed material on apple seedling growth
Two waste products, composted sewage sludge and fluidized bed material (FBM, a coal/limestone combustion byproduct) were used as soil amendments for apple seedlings (Malus domestica) grown in the greenhouse. Compost was applied at rates equivalent to 0, 25 and 50 dry metric tons/ha and FBM was applied at levels of 1 and 2 times the soil lime requirement on a weight basis (12.5 and 25.0 metric tons/ha). Plant growth was significantly increased by compost or FBM additions. Tissue Ca was increased by both waste, reflecting the high Ca inputs to the low fertility Arendtsville soil. Potentially high soil Mn levels were reduced by both wastes due to their neutralizing effect on soil pH. Root Cd levels were increased by compost additions even though soil pH was maintained above 6.3. Tissue Zn, Cu and Ni were not consistently affected by waste additions.
