One factor to consider with corn stover removal, the majority of the fall tillage that is done in Iowa is primarily to eliminate corn stover so that it is easier to plant in the spring and so that the soil will warm more quickly.  This fall tillage really opens the soil up to erosion and for a long period of time.  With careful harvesting of stover, many farmers could be convinced to eliminate their fall tillage entirely while leaving enough stover to provide erosion control benefits.

 

The net result if managed properly would be less erosion than now with an extra harvest of energy.

And given use of corn stover, higher rates of soil erosion (a problem all by itself) and nutrient loss (requiring more anhydrous), with resulting sediment and nitrogen in the waterways.

I was in the coop elevator in Nevada yesterday.  As I was waiting, there was a farmer who was whiling away the time who wanted to talk about the new cellulosic ethanol plant that will be built.  As background the elevator sits next door to the corn-ethanol plant in Nevada.  The DuPont cellulosic plant will also be built next door to the elevator.  The farmer was saying that the cellulosic plant is expected to bring in stover from a 50-mile radius of Nevada.  He was saying that without the stover on the ground, that there are only 2 options -- manure and more anhydrous.  Neither one of those sound like good options.  If you draw a 50 mile radius, that includes the watershed for the drinking water sources for Des Moines.  Apparently there has been a lot in the news in central Iowa about this cellulosic ethanol plant.  I wonder how much thought there has been about water quality changes that are expected as a result of the plant.

And probably many people who would like to get into or remain in farming who are being forced off the land because they cannot compete with the big guys. There are no farmers anymore, only producers.

PS--Regarding the objection that 1940s-era farming was much more labor-intensive than today, and therefore not a realistic option anymore, consider that we have a serious labor surplus now, with unemployment probably understated at the official figure of 9.1 percent.

Here's a central-Iowa water quality question for everyone:

 

If, in the watersheds that Des Moines gets its drinking water from--which are mainly the Raccoon River, but also, at certain times, the Des Moines River--we went back to farming methods that were in use prior to about 1940, which means no applications of anhydrous ammonia, would the Des Moines Waterworks need to continue using the major nitrate removal plant which they built a few years ago, in order to make our water safe to drink? (I remember reading that our nitrate removal facility is the largest of its kind in the world.)

 

Thanks for any comments on this!
