Abstract

Nursery experiments have shown that sulfur-coated urea was excellent as a slowly available form of nitrogen for ornamental plants in containers. Best plant growth resulted when the sulfur-coated urea was incorporated in the potting mix and the plants received fertilizer applications during the growing season. Even without additional fertilization, the controlled-release urea was able to supply adequate amounts of nitrogen for several months' growth. Excessively heavy applications resulted in plant injury and death.
