Jesus. Again, watch the film. Once plowed / cultivated / fully exposed to surface wind and sunlight.. tons of CO2 is given up by the soil.. permanently. It's not some ongoing cycle. Desertification is permanent unless drastic changes are made and sustained.
"looking for more missing matter"? What are you smoking? You're way smarter than this normally. Simply covering up large areas of exposed dirt with any plants / grasses drastically changes the climate. The light is absorbed by the plants which convert CO2 to O2 instead of just heating up and drying out the topsoil until it's literally reduced to dust. CO2 is pulled back into the soil once humous is successfully reintroduced.
I'm not going to spend one red cent on a film that's just going to tell me the exact same thing my mother has been harping on me for the past 50 years ... I've gardened every year of my life using these methods ... it's labor intensive and the food I produce every is
more expensive than the food I can buy at the grocery store ... right now I have alfalfa planted, and I'll turn that under this spring ... alfalfa is a nitrogen-fixer ... I don't suppose you know what that means or why it's important ...
I'm asking where all this CO
2 is going? ... we only measure 2.5 ppm/yr increase in atmospheric concentrations ... and that's only half of what we know we release with fossil fuel burning ... and for the record, I'm smoking Purple Trainwreak, 22.6% THC according to the government lab tests ... thank you for asking ...
By definition, humus is decaying plant material ... it's this alfalfa I'm growing right now that's absorbing CO2 and making structural proteins with it, only after I've turned it under will it begin to decay and provide nutrients for the soil microbes ... but that leaves bare Earth which you seem to object to ... in the natural setting, we'd have a layer of duff where most of the microbial action takes place, and below the dead root systems feed the actual soil ... it's a shame we've destroyed all this in Indiana, but if we try to restore it, the whole state would be a forest ... not much use as agriculture land ...
I don't have any personnel experience farming large tracts of land this way ... but there's quite a few of these types of operations along the West Coast ... folks out here are willing to pay the extra money for the foods grown ... so again, it's a 1st World solution to a 3rd World problem ... unlikely to work at all ...
