Coon Valley was the site of the first Soil Conservation Work for contour strips etc. to fight soil erosion. This was done against water erosion, at the same time SCS also started in Oklahoma against wind erosion. Coon Valley WI and some of the neighborhoods that surrounded it were home to some of the worst water erosion gullies etc in the United States, and hence was chosen as a location to start soil conservation research.
At the heart of the problem was the plow combined with hard rains and steep hillsides. Countour strips, terraces, grass waterways, etc all came about from here.
A google search of Coon Valley, SCS, Aldo Leopold might come up with some pictures that would be really gruesome to someone who makes their living from the land. that soil was gone forever... unless you owned some Mississippi Delta ground somewhere, then maybe you gained some of it!
I like old tractors, and I appreciate people wanting to work them- I do too. From a farming standpoint, though, I left the plow in the fenceline a long time ago. better for my soil, better for my fuel bill.
