EVALUATION OF NUTRITIONAL REQUIREMENTS IN NURSERIES OF TROPICAL SPECIES USED IN URBAN GREENING
.
One of the determining factors in urban tree development and growth is fertilization. We therefore studied the nutritional requirements of five tree species used in urban greening (Tabebuia chrysantha, Margaritaria nobilis, Hamelia patens, Apeiba aspera, Cupania americana) using the missing element technique. Differential responses by groups were found for nitrogen and sulfur deficiencies. The T.chrysanta, M.nobilis, and H.patens groups showed high sensitivity to nitrogen deficiencies. This was evident in a lower mean growth for all variables assessed: height, root neck diameter, aerial dry matter, and radical dry matter. The C. americana and A. aspera group showed the lowest mean growth for sulfur deficiencies. The HJ-Biplot representation... Ver más
