An interesting take

It would be interesting to note that plant roots are also a part of the soil biodiversity. A lot of plant roots exist in symbiotic relationships with fungi. They can thus be considered a part of the ecosystem.

Why is it important?

A rich soil biodiversity is important because:

  • Nutrient cycling
  • Essential for plant growth
  • Improve water entry
  • Help store moisture
  • Erosion resistant
  • Blocks pests and diseases
  • Carbon storage
