> Industrial farming depends on oil as a chemical input, because the soil has been sterilized and turned into dirt in most places by ammonia based fertilizers. The process of tilling the land resulted in most of the remaining dirt being eroded over the past century. What a piece of nonsense bullshit. 1. Ammonia can be produced without any oil. Natural gas (not oil per se) is simply used as an easy way to produce hydr…
The future of land management is going to be cultivating, curating, and generally taking care of the living, mostly fungal, part of the soil which will displace some or all of the straight up chemical additions instead enhancing the natural symbioses between root, fungus, and bacteria on an industrial scale... but until then chemical additions are fine. The issue going forward is going to be cost not an existential t…
Look, the hard truth is, nitrogen is the limiting nutrient. A square kilometer of plants can fix only so much of it on its own via symbiotic bacteria (and maaaaybe archaea), fungi can NOT fix nitrogen on their own.
You can optimize, curate, cultivate, paint yourself in dog shit and chant at the full moon however long you want, but there's a hard practical limit on that amount. And that's it.
Animals can concentrate nitrogen into manure, but they don't produce more of it.
That's why fertilizers are absolutely essential, as long as the Earth's population is above ~2B.
