I mean, we have been depleting soil fertility through the use of synthetic fertilizers for decades. It’s been a self-destructive cycle.
Perhaps some farmers might switch to practices that are not so dependent upon as much to external inputs … but even switching to things like no-till or using local inputs like manure, or using soil-regenerating practices like polycropping or integrated pest-control is going to take time.
It’s doable though. The Cubans have been operating their agriculture without imported oil and fertilizers since the US shut down imports. That also meant that use of tractors became limited, as are long-distance transport for food.
Better than food security is food sovereignty, and people within a locality being able to feed themselves.
