Study Notes
Soil Formation and Composition
- The primary factor responsible for the formation of soil from the parent material is weathering and erosion.
Soil Horizons
- The O-horizon of the soil contains freshly-fallen and partially decomposed leaves, twigs, and animal waste.
- The primary characteristic of the A-horizon of the soil is that it is rich in organic matter and nutrients.
- The C-horizon of the soil consists of broken-up bedrock and does not contain any organic materials.
Soil Pollution
- The primary cause of soil pollution is the presence of toxic substances, such as pesticides, heavy metals, and industrial waste, which can alter the soil's chemical composition and affect its fertility.
