Excerpt from Soil Improvement for the Worn Hill Lands of Illinois: With Special Reference to Southern Illinois These sloping hill lands are especially extensive in the seven southernmost counties of Illinois; also in counties bordering the Mississippi, Wabash, and Illinois Rivers and to some extent along other smaller streams. In most respects these hill lands are all very much alike and cer tain methods of soil improvement apply to all of them, especially for the so - called clay hills, the soil of which, however, is not clay in the true sense, but rather a silt soil consisting largely of silt, a grade of soil particles intermediate between clay and sand, with only a small admixture of true plastic clay. As to the composition of these worn hill lands, with respect to the essential and valuable elements of plant food, large numbers of analyses have shown that they are exceedingly rich in potassium, moderately well supplied with phosphorus, but exceedingly deficient in nitrogen. They are also very deficient in organic matter, or humus, and in southern Illinois, especially, these soils are acid or sour and consequently deficient in lime.
