Some Characteristic Soil Profiles in the North Central States

Comparing the two extremes; we find a range in rainfall from a mean annual of about 45 inches in southern Indiana to a mean annual of about 25 inches over much of Minnesota and in considerable areas of Michigan and Wisconsin. There is a general progressive diminution in the total precipitation from south to north. But this decrease is compensated to a great degree by the lower temperatures of the more northern region and by the fact that so much more of the precipitation is in the form of snow. Given similar textures end topographic positions., the soil climate is most likely wetter in northern Minnesota than in southern Indiana.
