The effects of drought, pedestrian, machine and vehicle traffic on soil is relatively quick and results in long lasting soil compaction. Soil compaction takes place when the soil structure is compressed and air is expelled and water permeability is reduced. This robs the soil micro flora and fauna of essential oxygen and water and dramatically slows or halts the organic regeneration process. Once the organic process is disrupted, plants and trees suffer as feeder roots decay and receive reduced nutrient flows. Suburban trees and plants are particularly affected by soil compaction and display significant decline when faced with compacted soils.
