The Soil Our Ancestors Built
Historically, human land use has more often depleted soils than improved them. As agriculture intensified, soils eroded, compacted, salinized, or lost organic matter — a pattern visible from ancient river valleys to upland farming regions worldwide.
Archaeology, geology, and agronomy tell the same story: productive land was pushed hard, then gradually worn down. Fertile land is often seen as something you’re simply lucky to have because of where you live — like the deep soils of the American Midwest or the rich, black soils of Ukraine.
But it may not be true that long-term fertility is something you only inherit from the land. Perhaps it’s something we can build — from soil that would otherwise be unsuitable for agriculture. Indeed, the historic and anthropological record is more complicated. There are world-wide historical and archaeological cases where rich agricultural soils were created by people in otherwise infertile areas.
