Changes in volume composition when the soil get compacted by heavy traffic

A well-managed soil has 25% air, 25% water, 1-5% organic matter and 45-49% mineral solids [Figure 1].




The compacted unamended landscape soil typically has 10% air, 20% water, 1% organic matter and 69% mineral solids. The most significant aspect of the compacted landscape soil is the reduction in air. Low soil oxygen is the most common limiting factor of plant (root) growth. [Figure 2]
