Landscape and urban trees may be growing in soils that do not contain sufficient available elements for satisfactory growth and development. Leaves and other plant parts are regularly raked up and removed, disrupting nutrient cycling and the deposition of organic matter back into the soil. It may be necessary to fertilize or to adjust the soil pH to increase available elements.
Fertilizing a tree with nitrogen can increase growth, reduce susceptibility to certain diseases and pests, and can, under certain circumstances, help reverse declining health.
