How to relieve compaction in soil?
If you want to relieve compaction, get an air spade. If you want to fertilize a tree, treat with a quick release fertilizer and amend the soil based on recommendations from a soil test. I would love for anyone to present a study that shows using a soil injector improves the uptake of a quick release fertilizer, or that it actually improves the overall pore space of the soil as I have searched and can’t find a single one. Spike aerators make holes too, but they actually make compaction worse, and I am highly skeptical of these beneficial claims.
Why do trees need leaves?
The leaves are natures way to fertilize the trees and by removing them you are removing the food for future years. Tree roots that are covered by grass add an additional problem for trees since the grass roots compete with tree roots for nutrients.

How to fertilize a plant?
Plants may be fertilized by either indirect or direct methods. With either method, apply the fertilizer to the entire root zone area. Because of the naturally high oxygen concentrations near the soil surface, a plant’s principal feeding roots are usually within the top 10 to 14 inches of soil. Many roots of mulched plants are located just beneath the mulch on the soil surface. Apply fertilizer to the surface of the soil or mulch; rainfall or irrigation water will carry it to the roots.

Why do plants grow so slow in drought?
Fertilizing your plants during a drought without watering in the fertilizer can also cause poor root growth. For one thing, plants need water to absorb nutrients, so dry soil will slow their growth.
Why do trees need fertilizer?
It results in an inability of the tree to retain water and a low level of nutrients in the soil. By injecting nutrients and organic matter directly into the root zone, this kind of fertilization helps to loosen the soil and give the tree roots room to move. When tree roots cannot move, they are unable to grow or feed.
What are the benefits of deep root fertilization treatment for trees and shrubs?
To start, this kind of fertilization restores essential nutrients that have been lost during the summer season. This allows the tree to absorb and store nutrients for the upcoming winter, increasing the chances of survival.
