How to Use Urea on Blueberries

Blueberries thrive in acidic soil, which is naturally low in nutrients. Nitrogen is particularly important for strong growth. Urea is used as an ammonium form of nitrogen and is generally the least expensive form of nitrogen you may buy. Research at the University of Kentucky has shown that blueberry plants fertilized with sulfur-coated urea yield more than those fertilized with ammonium sulfate, another form of nitrogen fertilizer. Urea should be applied in spring and again right after harvest.

Instructions

- 1
  Gather soil samples and have them analyzed by your county cooperative extension service. The results will help you determine how much urea to apply to the soil around the blueberry plant.
- 2
  Apply the urea at the rate suggested by the soil analysis to the soil in a circle, 18 inches in diameter, around the blueberry plant. The age of your blueberry plant is also a factor in the amount of urea to provide. The University of Nevada Cooperative Extension provides a chart of recommended application rates on its website.

  Water the application area to activate the urea and soak it down to the blueberry bush's roots.
