An overview of historical development of shade-tree fertilization practices and current state of the art is presented. Research involving 6 shade tree cultivars and their response to 4 fertilizer formulations and 2 methods of application is reported. Test results show that on phosphorus deficient soil, broadcast application of a slow-release complete fertilizer yielded larger trees than any of the other treatments. Urea formaldehyde applied in 46 cm (18 in) deep holes stimulated shade tree development least. The section, Application of Research Findings, covers applications of the ‘Universal Tree Fertilization Calculation’ formula for determining the amount of fertilizer to apply per tree based on the radius of the root system.
