Even if the soil is preserved, we’ve been mining the micronutrients from it and generally only replacing the 3 main macros for centuries. It’s one of the reasons why mass produced produce doesn’t taste as good as home grown or wild food. Nutritional value keeps going down because each time food is harvested and shipped away to be consumed and then shat out into a septic tank or waste processing facility, it doesn’t end up back in the soil as a part of nutrient cycles like it did when everything was wilder. Similar story for meat eating nutrients in a pasture.
Insects did contribute to the cycle, since they still shit and die everywhere, but their numbers are dropping rapidly, too.
At some point, I think we’re going to have to mine the sea floor for nutrients and ship that to farms for any food to be more nutritious than junk food. Salmon farms set up in ways that block wild salmon from making it back inland doesn’t help balance out all of the nutrients that get washed out to sea all the time, too.
It’s like humanity is specifically trying to speedrun extiction by ignoring and taking for granted how things work that we depend on.
It makes sense that growing a whole plant takes a lot of different things from the soil, and coating the area with a basic fertilizer that may or may not get washed away with the next rain doesn’t replenish all of what is taken makes sense.
But how would adding human poop to the soil help replenish things that humans need out of food?

Why would good nutrients end up in poop?
