Desert Strip Farming, a Modified Dry Farming Method Using Rainfall Multiplication
Reviews progress to date on a runoff distribution strategy in which rain water is harvested in collectors and then channeled to nearby crop areas. The report explains that an inexpensive short-distance irrigation method is badly needed in sunny, potentially arable regions where the limited rainfall is lost through excessive runoff. The basic principles and history of the proposed runoff distribution strategy are outlined and a diagram of its operation is provided. The report next describes a conceptual model of the strategy. The model was developed to determine the most successful ratio of crop area for any region of known hydrologic and soil characteristics. Finally, a computer program for the testing model is discussed in detail, and ongoing field validation tests now being conducted near Tucson, Arizona, are described. Although no crop yield or crop survival rate results are yet available, it is felt that the desert strip farming runoff strategy is promising. Rainfall charts and a map are included.
