WebSoils are named and classified based on their horizons. The soil profile has four distinct layers: 1) O horizon; 2) A horizon; 3) B horizon, or subsoil; and 4) C horizon, or soil base ( Figure 31.7 ). The O horizon has freshly decomposing organic matter—humus—at its surface, with decomposed vegetation at its base. WebOct 31, 2024 · The results suggest that vegetation changes over the last eight millennia are primarily the result of human disturbance, fire and climate change.
