"Crabbe, what happens to the nations topsoil when everything is stripped off for food and the ethanol plant? A partial answer is found here.."

"He contends that corn producers can get about $100 per acre for stover that has zero value once it decays into the atmosphere as CO2. But what happens to soil tilth after years of stover removal? Loren said that a 30-year trial at the University of Minnesota’s West Central Experiment Station in Morris with corn cut for silage each year versus stalks plowed into the soil showed no difference in organic content."

If there is no difference in tilth after 30 years of silage production, why would there be a difference in soil tilth after 30 years of biomass production?? I often have the misfortune of driving by a dairy farm West of here, it grows corn for silage, transfers manure to a septic pond, and then pumps the septic water onto the corn field, no real solids are returned, but the soil is similar after 15 years of this as to when it was started from pasture fields. (unfortunate because the septic pond has an aroma, as does the irrigation).
