Abstract: Highbush blueberries ( Vaccinium corymbosum L.) were fertilized with equal amounts of nitrogen from ammonium sulfate (AMS) or sulfur-coated urea (SCU) for 6 years. The plots treated with SCU yielded significantly more than the AMS plots three out of the five harvest years. Except for plant size in 1984, treatments did not significantly affect berry size, plant survival, and other vegetative characteristics. Soil pH after 5 years was significantly lower on the AMS treatments than on the SCU-treated plots (5.4 vs. 5.7). The nutrient content of the leaf tissue did not differ significantly by fertilizer source. At the rate used in this study, SCU would be an acceptable nitrogen source for blueberries compared to AMS, but SCU is less effective in maintaining low soil pH.
