Abstract
Abstract Foliar analysis data (N, P, K, Ca, Mg, Na, Zn, Mn, Fe, Cu, and B) and growth parameters (flower diameter and dry weight and flowering stem weight and length) indicated that municipal compost could be used as a soil amendment for chrysanthemum culture. Compost amendment produced plants high in foliar K, Cu, B, and Zn. A marginal leaf injury was observed in compost-grown plants. While K, Cu, and Zn toxicities were disproven, B toxicity still remained a possible explanation for the symptoms. Plants grown in perlite media were high in K, Ca, Cu, Al, B, and Zn, and perlite amendment may have accented the leaf injury observed in compost media. Negative correlations of growth parameters occurred with foliar K, Cu, Al, B, Na, and Zn concentrations.
