The Forest & The Soil Cycle
Forests protect our soil from erosion acting as a sponge and filter. Trees drop leaves, branches, bark and seeds to decompose and add needed nutrients to the soil. The cycle is complete when the roots of a tree are fed by components in the soil and the tree grows more leaves to create more organic matter.
