Fertilizer Injections

Liquid injection involves placing fertilizer as a liquid suspension or solution into the soil around the tree or the water supply utilizing the irrigation system. One advantage of liquid injection is that by applying fertilizer below the soil surface in a more targeted chemigation, you can make certain that nutrients, such as phosphorus, are more available to tree roots by placing them below the thick turf zone.
