Agricultural Greenhouse Gasses & the Carbon Cycle
"Carbon is the currency for most transactions within and between living things." - Christine Jones
"the trouble isn't the carbon itself; it's that there is too much of it in the air rather than in the ground, where it lends fertility to the soils." - Judith Schwartz
Industrial Agriculture has resulted in enormous environmental damage including significant greenhouse gas emissions. By constantly fighting against nature's way of doing things nature's balanced carbon cycles - that have evolved over millions of years - are broken. By changing to mimicking nature and working with nature we are able to fix and indeed accelerate these broken carbon cycles and reduce the environmental and climate damage.

Real carbon cycles are of course more complicated than those depicted in the diagrams below and they link in with water cycles and other mineral cycles but these simplified diagrams highlight the complexity and lack of cycling in Industrial Agriculture with the simplicity and balanced carbon cycling of Regenerative Agriculture.

Ruminants belch methane as they break down plant cellulose but this is part of a natural cycle. There have been 100s of millions of ruminants on the planet for millions of years and they never pushed up greenhouse gas concentrations. As this image from independent research done on White Oak Pastures farm shows how properly managed cows on grass are part of a natural grassland carbon cycle. This is very different to monoculture cropping and animal confinement (feedlots) both of which take carbon from the soil and emit it into the atmosphere.
To reduce emissions and reinstate natural carbon cycles we need to:
- Stop ploughing
- Stop applying synthetic fertilisers
- Stop monocultures
- Stop spraying chemical
- Ensure our soils are covered with crops at all times
- Get ruminants into crop rotations
- Close feedlots down
- Get ruminants grazing on the fields that used to provide grain for feedlots
- Get high impact, long rest, planned grazing on grasslands
