Carbon in stable Humus form, determines soil fertility. Soil with Humus:

• Holds nutrients and prevents leaching – CEC
• Acts like a sponge, absorbing moisture, critical during dry spells.
• Traps oxygen, essential for root development.
• Feeds and protects microbial biomes in the soil.
• Prevents erosion by holding soil particles together.
• Have the capacity to chelate metal ions, making micro elements available to plants.
• Protects soil from extremes in temperature.
• Buffer soils against pH fluctuations.
