Soil has a problem. It is eroding faster than it is being made. That's a given in these times of relative geologic stability. Most soil was formed in depositional material. Without sedimentary deposits being exposed by tectonic processes, without substantial volcanic ash fall, without the continental glaciation producing silt, and without the global wind storms and cataclysmic post-glacial flooding to redistribute that silt, we basically have to wait on the next climate change re-boot for our next era of major soil replenishment. In these trying times on the downhill slide from peak soil resources, we'll have to make better soil from the soil that we have left.
