SOIL AND Water AS ABIOTIC FACTORS

SOIL QUALITY IS BASED ON

• Soil Profile/Horizons
• Composition
• Texture
• Particle Size
• Permeability
• pH level

SOIL PROFILE/HORIZONS

• Litter- loose layer of plant remains
• Horizon A-valuable topsoil that has humus clay,and minerals. Most animals live here rich in nutrients
• Horizon B-Subsoil-with little humus
• Horizon C-Parent material
• Bedrock
