DEVELOPMENT OF METHODS OF NITROGEN MANAGEMENT FOR WOODY ORNAMENTAL SPECIES IN LANDSCAPE PLANTINGS
The primary purpose of this experiment was to evaluate the effects of fertilizer nitrogen source on survival and growth of several woody ornamental species used in highway plantings. Even without nitrogen fertilization, very satisfactory growth occurred. All fertilizer sources provided satisfactory plant growth at a 0.4 lb N/cy yds rate. Slow-release fertilizers applied at a 2 lb N/cu yds rate approached the maximum rate of application. The system used to control soil water evaporation appeared to be effective. Direction of exposure appears to have little influence upon the growth of these species.
