Carbon Sequestration in Soil
Why Carbon Sequestration in Soils?
Carbon dioxide in the atmosphere, which is a greenhouse gas, is the biggest contributor to the climate crisis. Carbon offset programs usually seek to reduce the amount of carbon dioxide and other greenhouse gases entering the atmosphere and this is good. However, it is taking too long to make the switch away from fossil fuels. We need to simultaneously, and quickly, remove enough carbon dioxide from the atmosphere to give us the time we need to make the switch.
Engineers tried to do this without much success. However, plants can do this for us naturally and far less expensively and this carbon can be stored in the soil permanently through biological farming.
How does Soil Sequestration of Carbon Work?
All living cells, including bacteria and fungi, are mainly made from carbon, which is captured by plants during photosynthesis. In natural systems plants move this carbon into the soils where it is stored if the soil ecology is working. Such plants produce root exudates that feed huge populations of beneficial bacteria and fungi. They also produce a lot of debris that decays and is incorporated into the soil.
Our farmers are already creating millions of acres of healthy soils by reintroducing the full spectrum of soil microbes and other life into the soil. They do this using a science based approach which includes identification of all critical microbes and soil organisms with a microscope. Also involved is the use of compost in solid and liquid form, cover cropping and no-till agriculture, along with the introduction of deep rooting grazing grasses and managed grazing protocols.
Big Agriculture: It's the Cause, but Could Also be the Cure
The problem is that our industrial farming methods are rapidly destroying the soil organisms which capture and hold carbon. The UN Food and Agriculture Organisation estimates that, on average, we have only 60 more harvests globally before the soils die and yields dwindle away. This is due to the destruction of soil life which binds carbon and creates a healthy ecosystem in the soil.
The good news is this... when we switch to science-based biological farming practices globally we can reverse this destruction of our food producing capacity. This switch to more natural farming increases yields while we grow the carbon in the soils and harvest more nutritious crops.
