  • Maintaining healthy soil is an important element of regenerative agriculture - increasing soil fertility, biodiversity, water retention and storing carbon.
  • Plant health relates to soil health.
  • Plants are more able to resist pests and diseases in healthy soil, so less need for pesticides.
  • Healthy soil has a good balance of inorganic and organic components as well as micro and macro-organisms.
  • Healthy soil retains enough air and water for good plant growth.
  • Healthy soil has an important role in capturing and keeping carbon in the soil (carbon sequestration).
  • Soil can be tested for minerals and pH.
  • Soil health can be improved using compost, green manures and limiting tilling.
