We're not having the same conversation. You're talking about a farmer mapping his fertilizer needs to specific areas of his fields. My original posting dealt with maps of the US showing average yields. As an aside (since this is not what I originally wrote about), I doubt that most farmers are up to the level of agricultural sophistication that you speak of. I think that's still pretty much "cutting edge" stuff. Yes, I've seen the booths at the Ohio State Fair on that, but most farmers that wander by just grin and shake their heads. Most farmers don't "drive this year's tractor pulling next year's combine", to use a common phrase. (And yes, the really slick combines are self-propelled.) Even with extension agent services available (I get the newsletter from my extension agent in White and Van Buren Counties in Tennessee), most farmers are still a bit more low-tech in their techniques. I would not be surprised to find that the same tractors and combine my grandfather and I used to harvest oats, wheat, and soybeans are still in use by some small-farm operator in Ohio.
