ABSTRACT:
A method and apparatus is provided to conserve moisture for growing crops. An over-the-field carrier is provided with harvesting means for severing a prior year's crop stubble from a field. The leaf and stalk material are separated and the leaf material is retained for feed while the stalk material is returned to the field for building up the organic matter in the soil and also controlling erosion. Cultivating means may be incorporated on the carrier to work the soil and enhance the effectiveness of the recycled stalk material. In areas where sufficient moisture is a major concern slotting apparatus is incorporated onto the carrier to form a longitudinally and vertically extending slot through the field. This slot is then filled with the separated stalk material which is effective in retaining water entering the slot. An inclined and compacted watershed area is formed on either side of the slot by grader blades and rollers. This serves to direct runoff water into the slot where it will be retained for use by growing plants.
