Did you know?
It’s common knowledge that tree roots can extend far below the ground that we walk on, but did you know that tree roots may extend up to three times the height of the tree away from the trunk? In fact, much of the trees root system lies just a few inches from the soil. Because of this, soil compaction can be extremely harmful to some species of trees. It is a major cause of tree decline in urban areas because cars, foot traffic, and pavement reduce the amount of air flow to the trees roots. While soil compaction is easily preventable, it is difficult to reverse once the damage has been done. Some signs of soil compaction to look for include standing water that does not easily drain into the soil and excessive water runoff, hard soil that is not easily dug with a shovel, and poor plant and grass growth around the area. Also look for structural soil crusts which are dense layers of non-aggregated particles on top of tilled ground.
