What is Soil Carbon?
It is estimated that at least 50 percent of the carbon in the earth’s soils
has been released into the atmosphere over the past centuries. Bringing that carbon back home through regenerative agriculture is one of the greatest opportunities to address human and climate health, along with the financial well-being of farmers (Hawken, 2017).
There are more organisms in a teaspoon of healthy soil than there are humans on the planet. Of the 3,170 gigatons of carbon found in terrestrial ecosystems, 80% can be found in the soil (Lal, 2008). This is more than 3 times more than the atmospheric pool (Oelkers & Cole 2008).
There is a growing body of evidence supporting the hypothesis that the
earth’s climate is rapidly changing in response to continued inputs of CO2 and other greenhouse gases (GHGs) to the atmosphere resulting from human activities (IPCC 2007).
The demand for carbon credits worldwide is growing as we move into a new era of valuing natural resource capital. This presents opportunities for all farmers (cropping, grazing, large or small scale) to generate a new income stream by farming carbon that will diversify and stabilise on farm income.
