The soils here are quite different, there are sandy ones, there is heavy red clay, there is even white clay from which porcelain teapots are made, there are peat bogs. In the place where I specifically live, the soil is heavy clay, and it is customary to add sand and humus to it so that it is loose. If you move away from my house for 8 km, then there is a lot of sand, so much that for many years it was mined for construction needs using heavy excavators.Looking at this picture,, I judge that the soil is sandy. Areas with such soil types are great for planting potatoes. I remember you posted about planting potatoes,,, and everyone else in your vicinity. Of course fertilizer is needed to get a good crop,, but the sandy soil is equally important. In my area,, the soil is not ideal for such,, to grow potatoes. commercially. Yes,, there are individual gardeners that do so,, but with much added amendment to soil. Potato growing areas are 250 miles to the north of me.
@pennyJo1960 ,, were you in potato zone,, or corn zone when you were in Wisconsin??
Potatoes are grown here, if we take the area in the photo, then not far from it there is a former Soviet state farm, where potatoes have been grown for a very long time.
I can also find many glacial boulders in the soil here, which are usually used to decorate flower beds, build fountains and other things.
