- 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.
