A South Dakota State University study showed that soil untilled for six years was able to absorb ten inches of rainfall for a two hour period, compared to 0.6 inches an hour for a plowed portion. Earthworm channels were felt to be the factor on the untilled soil. Tillage cuts off the channels from the surface.
9962. Chilcott, E.C.. 1910. A study of cultivation methods and crop rotations for the Great Plains area.. USDA Bureau of Plant Industry, Bulletin 187. 78 pp..
This paper reports the results of a four-year experiment in crop rotation and cultivation methods conducted at eleven stations in the Great Plains area. Some of the questions asked of this experiment were how can the largest average yields of corn, spring wheat, oats and barley be obtained, do moisture conservation methods pay where continuous cropping to the same crop is practiced, and can green manuring be profitably substituted for summer tillage? The results found that a 3-year rotation of corn, wheat and oats gave the most profitable returns. Continous cropping with moisture conservation methods of fall plowing and fall, winter and spring tillage did not give results to warrant its recommendation. The most highly recommended practice was that of green manuring. For greatest benefits to the soil, it was recommended to plow in a green manure crop in early season, with little summer tillage, until wheat planting time.
