Isn’t sustainable regeneration of farmland primarily concerned with the… nitrogen cycle?
Carbon is of course a factor in the case of stubble burning, but short of that biomass is being pulled from the atmosphere?

- TaylorAlexander 3y agoPlants get most of their structure by pulling in carbon from the atmosphere and using it to make more plant. Regenerative organic farming generally works to keep that captured carbon in the soil, by using excess plant matter as soil amendment, to put it simply. From what I have seen this has the potential for massive carbon retention over chemical intensive industrial farming which generally does not focus on the use of organic matter as soil amendment.
- sp332 3y agoGood soil has benefits but plants don't get carbon from their roots. They make sugar in the leaves and make that into more complex molecules for growing.
- TaylorAlexander 3y agoThe plants get carbon from the atmosphere of course, but retaining organic matter in the soil, which captures that carbon, has other value. "Soil organic matter significantly improves the soil's capacity to store and supply essential nutrients (such as nitrogen, phosphorus, potassium, calcium and magnesium), and to retain toxic elements. It allows the soil to cope with changes in soil acidity, and helps soil minerals to decompose faster." https://www.google.com/search?q=benefits+of+soil+organic+matter https://www.google.com/search?q=benefits+of+soil+organic+mat...
- dscottboggs 3y agoLol the "nitrogen cycle" is dead at most "modern" farms. They kill all the microbes that perform the nitrogen fixing and then add it back in manually.
- conradev 3y agoExactly, I thought one of the goals of regenerative agriculture was to reduce or eliminate fertilizer usage to prevent runoff
