Interpretive Summary:

Technical Abstract: Published results of research on alternative residue management on furrow irrigated land to reduce irrigation-induced erosion is reviewed and new data on the amount of water infiltrating fields farmed with traditional and conservation tillage approaches are presented. Results showed that more than three times the amount of water infiltrated moldboard plowed land as no-till land during the first irrigation of corn. A similar ratio of infiltration was measured when comparing reduced tillage and traditional tillage bean crops following winter wheat. Conclusions of these studies are that crop residues can be managed so that furrow irrigation can be accomplished with high uniformity with crop residues on the surface and that moldboard plowing to bury crop residue wastes irrigation water and enhances the probability of nitrate leaching.
