Study Notes
Factors Involved in Soil Formation
- Five primary factors: parent material, climate, biological agents, topography, time.
Parent Material
- Determines the mineral composition of the soil.
- Composed of residual soil (from underlying rock) and transported soil (moved by water, wind, etc.).
Climate
- Influences soil characteristics through variations in temperature and precipitation.
- Different climatic conditions can lead to distinct soils even from identical parent materials.
Biological Agents
- Include decomposers like bacteria, fungi, and earthworms.
- Affect the rate of organic matter decay and contribute to humus content in the soil.
Topography
- Refers to variations in elevation, slope angles, and slope orientation.
- Influences drainage and erosion, affecting the soil formation process.
Time
- Longer periods allow for more extensive and mature soil development.
- Soil characteristics evolve through the accumulation of organic matter and mineral changes over time.
