If you’ve got the luxury, you can also let fields go fallow and rotate crops to avoid fertilizer. That obviously requires more land though

This thread is weird. It seems like you all never heard of compost.

Does that work long term on a commercial scale without egg shells/ bone meal? Afaik, there needs to be an additional source of calcium, but that could of course also supplement crop rotation/fallowing.

Though tbf, limestone is very soft and I could see supplementing with ground limestone.

Eggs shells don't work unless they're ground into a very fine powder.

I don't know the answer to this question. You may be right. And yea, I can see limestone in the right doses working.

And we could always extract the nutrients from our waste. Close the cycle: what goes in, goes out. We're already using biosolids in agriculture.
