I think Mike means well but he is always fear porning whether on purpose or not.
Farmers may have to think outside the box as the situation won't get better with Prezident Buzzard in control. Instead of purchasing pounds of chemicals, maybe they can use peat or burnings from forest fires, or?
Maybe all that is only doable by small farmers and homeowners with their own gardens, I don't know.
On broad acre scale those sort of approaches aren't currently practical. Without petroleum based fertiliser much of modern would collapse. Farms have been getting bigger and bigger, the 5000 acre farm I grew up on is now considered small, even that would be impractical to go organic suddenly. The soils are very depleted and in extremely poor health. Years of modern farming practices have destroyed the microbiome. To rebuild that will take decades, in which time many will starve.
Mike might be a panic monger, but I think he's right here. The food shock will be the final of the four shocks and the most deadly by far.
I now live on 5 acres (bought some years ago on the expectation of some sort of zombie apocalypse). It would be possible to live somewhat sustainably on this land, but would require devoting much more time to for production. Chickens are essential, converting food scraps grass and insects into quality protein and fertiliser for the garden. In a survival situation, food that stores or can be preserved will be essential. Potatoes, pumpkin, carrots (stored correctly), etc. We wouldn't starve but it wouldn't be pretty.
