  Requires a subscription. 'Replace it' is a little imprecise here, allowing for substitutes. I'm sure some people are trying to make substitutes but we know a lot more about how soil becomes these days and we're able, to an extent, to create it by introducing food to the right food chains. Unfortunately for perennial crops, you have to build that food chain up orders of magnitude more than you do just for annual plants. At the same time the carbon content and resiliency are much much better. Elaine Ingham is worth some time in a search engine.

    I don't have a subscription. I found it by googling, maybe that gives you a one time pass
