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.
