“If the soil is structurally and nutritionally conducive to a balanced, thriving soil fauna, bacteria tend to penetrate further; top soil becomes deeper and richer; plant growth becomes healthier and more luxuriant. When plants are abundant, wildlife is better nourished and more plentiful. If any external element disrupts this cosmos, the soil deteriorates and the living things that occupy the surface are adversely affected.”
