Granited.

Soil is enriched after the blow, at least downwind.

But only after the devastation. How many years of ash will it be before Kansas, Colorado, Iowa, OK, and Nebraska wheat, corn, and soy bean fields are back at full production?

But only after the devastation. How many years of ash will it be before Kansas, Colorado, Iowa, OK, and Nebraska wheat, corn, and soy bean fields are back at full production?

I'd say two years in starting back to production in the Great Plains after the event.

I'd say eight to ten years after the event until back to close to full production.

I figure an event like this to the Great Plains would be like the 1930's dust-bowl times ten.
