effect on bulk density aggregate filtration aeration root plant

  • The Effects of Soil Compaction Iron Tree Service

    The Effects of Soil Compaction: As soil particles are pressed together, soil experiences an increase in bulk density. This increases soil strength, but causes the destruction of large pores, which are responsible for air and water movement. As a result, less water can pass through the soil, increasing the potential for runoff and soil erosion.
