This article provides an excellent coverage of the history of stubble mulch equipment from 1933 to present. Starting in 1933 with Hoeme's cultivators for deep primary tillage that left clods on the ground, Noble's (1936) undercutting tiller, and in 1939, Russell and Duley began experimenting with a tiller that would cut off weeds at subsurface while leaving straw residue on the surface. This became known as stubble-mulch tillage. With the use of stubble mulch tillage came the advent of shovel press drills and eventually air-seeders.

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.
