Maybe this is confirmation bias-but IMHO this proves my Jevon's paradox theory. High yielding, intensive & destructive cropping methods DO 👏 NOT 👏 SPARE 👏 LAND. Tilled, sprayed, & row-cropped grasslands never revert back to their OG conditions. Ever nature.com/articles/s4146…
What is the point of using cropping practices that lead us to abandon lifeless cropland soils years later, only to convert more ecologically sensitive (& lower yielding) plains grasslands to grow these same crops, using the same practices?
TL;DR - there's a half-life to intensive commodity production, and it comes at the cost of converting some our most prized ecosystems. Lose-lose-lose all around for wildlife, native plant reservoirs, and soil carbon.

THREAD: What happens to #carbon once it's sequestered in soils? How can we lock it in & ensure it doesn't return to the atmosphere as CO2?

Soil scientists use "fractionation" methods for that^. Fractionation tells us about different pools of C-some stay forever & some are quick
Consider it like food for the body.

Some of the energy in your food will get used to build your bones-it stays there & is permanent. Some of the energy gets digested & respired as CO2 when you breathe. Not permanent, but you still need it. & some is intermediate-stored as fat.
In soils, we call the permanent fraction MAOM (minerally associated organic matter). This is the soil C that gets stuck to minerals & stays forever.

The faster fraction is called POM (particulate organic matter). This pool is a lot more dynamic

1. You might find it ironic that my stepdad works at Perdue Farms chicken plant in rural GA, where 3 people have tested + for COVID. My mom is a nurse. Both recently quit smoking after 20+ yrs.

This executive order puts them even more at risk.

COVID has exposed the absolute lack of resiliency in our concentrated food system, w/ meatpacking companies among the worst. They fail pretty often: JBS gets fined for fraud, Tyson gets a slap on the wrist for price setting.

But then nothing changes. Ever.
DECENTRALIZED 👏 FOOD 👏 IS 👏 ESSENTIAL. Not the interests of the meat majors. It is no coincidence that the companies who help destroy the env also put our families (their workers) at risk to make a buck. We've essentially given them permission to over and over and over.

Some common misconceptions about grazing, GHGs, and soil C I’ve heard that negate the actual science (a thread):

1. “Properly managed cattle on grasslands sequester enough C to offset all their GHGs”
A: sometimes, but that’s certainly not unilaterally true.
2. “Methanotrophs in well managed grasslands offset all of the methane from grass fed cattle.”

A: absolutely false- no data to support that. We can’t even culture methanotrophs, and the best estimates show a marginal level of CH4 oxidation compared to enteric CH4 production.
3. “Consumers will pay more for meat labeled with regenerative.”

A: Yea-probably not. The only market based label to break 5% market share was Organic. Consumer surveys show that consumers say they care.... but most of them don’t put their $$ where their mouths are. Also, equity
