Throughout the soil there is a proliferation of beneficial bacteria and fungi such as mycorrhizae. They help plant roots find nutrients and moisture, which may often have been present already, but sometimes remains unavailable to roots if biological activity is low.
Soil structure
No dig allows soil to develop its own aerated structure, so that vegetables and flowers are able to grow more easily. Weeds grow less because undisturbed soil does not need to recover.
This process saves time, as there is less digging and watering, but gives bigger harvests. It is also ecologically beneficial as we create an ecologically balanced environment, use fewer chemicals and keep carbon in the soil.
