> What do you mean by engineered? In a pasture for instance, grass can grow because the plant incorporate enough organic matter in the soil to be consumed by microorganisms that will in return fixate the nitrogen from the air into nitrates that can be consumed by the plant. Then you have some equilibrium-ish (it depends on the seasons and the precipitation so it's not an actual equilibrium) amount of nitrogen and org…
I think at that point the phrase "engineered soil" loses all utility. We've been engineering soil with domesticated herd animals since prehistory, bringing fertilizer from pasture to arable land at the very least. If we look further at the most recent archaeological research on cultivation, there's growing evidence that soil engineering is how societies move from cultivation-assisted hunter gatherers to fully sedenta…
The same way, humans have engineered forests since prehistory, but there's still a massive difference between a prehistoric forest and a modern exploited one.
