To be brief, it's hard to put an opinion on exactly what the dollar value is, but there's going to be an impact on grain prices locally. Particularly in the local region, there will be a boost to the local grain prices, which means new revenue for farmers. There will also be an impact on the stability of commodity pricing, which gives stability to the farm. New revenue to the farm means fewer payouts from the government to support programs.
