Roots are the organ of a tree that serves to maintain mechanical support, to provide essential elements from the soil absorption, and to store energy reserves. (Dr. Alex Shigo, p.94) The roots provide the upper transport system and leaves with water and element/minerals while the roots depends of the phloem the food from the upper transport system and leaves. So in turn a strong root system means a strong transport system and leaves and vise versa. Many of the above ground symptoms of the problems are secondary to the roots problems that are primary issue; to understand roots one most know how they grow and function.
The tip of a root is covered by a thimble like root cap, which protects the delicate apical meristem as the root punches through the abrasive soil during primary growth. The root cap also secretes a polysaccharide (Cellouse) slime that lubricates the soil around the tip of the root. The primary root gives rise to lateral root, also called branch roots. This type of root stores sugar and starches that the plant will consume during flowering and fruit production. Fibrous roots grow off the lateral roots, which both types of root have root hairs. Root hairs and fibrous root are both designed to increase surface area for the absorption of water and minerals.
Soil Compaction is a major problem that trees face each day in urban environment and in the forest because of human interaction. Soil compaction can occur from lawn tractors, lawn rollers, heavy foot traffic, vehicle off pavement, and construction equipment. As the soil becomes compacted the pore space between minerals and organic materials is reduced, water and air can’t accumulate a decrease in supply for roots to absorb, along with the roots have a reduced amount of space to grow.

These root system problems that can lead to your tree being in poor health or dying is to take proper preventative steps to stop the occurrences causing the problem or reverse the damage already done. Soil compaction can be prevented by hiring a consultant to draft a plan for the contractor to follow to decrease the risk of both soil compaction and root damage. Consultants can also be hired onto, also enforce the policy of a plan written. Planting and transplanting tree(s) into compacted soil area cause many different problems that could lead to a short lived tree or unhealthy tree.
