Summary The effect of one application of the slow-release fertilizer, sulfur-coated urea, on the nitrogen level in leaves, fruit and bark of Washington Navel orange trees was studied during the different periods of the annual vegetative cycle, in comparison with two annual applications of the fertilizer ammonium nitrosulphate. Results indicate that a single spring application of 750 g nitrogen per tree maintains N levels in old leaves, spring shoots, ovaries, fruit and bark statistically equal to those obtained using double doses of ANS in two applications.
