Soil world wide is decreasing in quality. Wasteful farming practices, slash and burn farming, erosion, monoculture farming, heavy pesticide use, making pesticide resistant crops so you can use more pesticide, etc. Seems far from sure that a world wide cloud of ash might well do more benefit (better soil, cooler temperatures, helping dead zones in the ocean) than harm.... assuming we plan for it.
