Soil permeability is _______ in loose soil.

🔑 The Soil Horizons and Their Characteristics:
🌍 B Horizon or Subsoil:
→ Subsurface layer reflecting chemical or physical alteration of the parent material.
→ Accumulates leached minerals from A and E horizons.
→ Contains iron, clay, aluminum, and organic compounds (illuviation).

🌍 C Horizon or Parent Rock:
→ Contains weathered parent material from sedimentary deposits.
→ Composed of large unbroken rocks.
→ May accumulate more soluble compounds (inorganic material).

🌍 R Horizon or Bedrock:
→ Denotes partially weathered bedrock at the base of the soil profile.
→ Composed of continuous masses of hard rock.
→ Soils formed in situ resemble this bedrock layer.
→ Located under 50 feet of the other profiles.
→ Also known as the D horizon in some cases.

🧠 Concept: Soil Properties
→ Soil is a mixture of microorganisms, organic matter, and minerals.
→ Each layer differs in feel (texture), colour, depth, and chemical composition.
→ These layers are referred to as horizons.
→ The uppermost layer of soil is generally dark in colour as it is rich in humus and minerals.
→ The mixture of rock particles and humus is called the soil.
→ The properties of soil are helpful in understanding the nature and kind of soil.
→ Soil quality can be monitored by physical, chemical, and biological indicators.

✔️ Explanation: Soil Permeability
→ Soil permeability is the feature that determines the movement of water in the soil.
→ It is higher in loose soil with macropore spaces and lower in compact soil.
→ The higher the permeability, the higher will be the rate of transmission of water and air.
→ If water and air transmit deeply into the soil, it will be beneficial for both the plants and the soil.
→ Clay is the most porous sediment, but it is the least permeable as it is not loose soil.
→ Thus, soil permeability is greater in loose soil.
