In the 1930's thousands of acres of land were rendered unproductive through wind erosion because of drought, tillage, and dust mulch farming practices. Charles S. Noble, of Nobleford, Alberta, invented a cultivator that sheared stubble and weeds below the ground surface, leaving residue on the soil to reduce evaporation and prevent erosion by strong Alberta winds. The Noble Blade Cultivator was patented in 1937. The Noble family subsequently developed a variety of straight and V-blade cultivators.
