Excerpts from the report: As in many other wheat-producing areas, stubble mulching has been found by research and experience to be one of the simplest and most effective management practices to protect land from erosion. Residues from the last crop are used as a mulch, held to the land by standing stubble, to conserve moisture and to prevent the soil from washing or blowing away ; thus the term "stubble mulching." This bulletin describes the machinery, and the sequence and methods of operation that have been found best for stubble-mulch farming in the Pacific Northwest wheat areas. Although directed primarily toward solution of erosion problems in that area, the information is applicable, wholly or in part, to other areas in the West where similar problems are encountered.
