It’s all about the biology…
When Soil is healthy, it is packed full of microbes. These microbes live in symbiosis with the plants. The plants photosynthesis and feed the microbes sugars, in turn the microbes feed the plants minerals and nutrients.
Through the use of chemicals and industrial farming practises, or contemporary garden and landscape management approaches, much of our Soil has been stripped of its biology and is turning to dirt. Plants growing in dirt need constant synthetic inputs to ensure survival, they lack nutrient density and they are susceptible to disease. With a lack of Soil biodiversity, there is a lack of above ground biodiversity too, not only this but dirt cannot hold water, losing valuable soil carbon into the atmosphere as atmospheric CO2.
Our friends at Kiss The Ground have explained this beautifully in The Soil Story Video below.
