Either straw incorporation or cultivation of the furrow bottom greatly increased furrow infiltration into a sandy loam soil during a 3‐year study period. Straw incorporation became less effective as the season progressed. A single straw application of 13.4 tons/ha lasted until midway into the second irrigation season. The cultivation treatment caused serious erosion when furrow inflow rates were about 6 liters/min or more. The straw prevented erosion at all inflow rates (up to 8 liters/min). Organic matter contents were significantly increased by the incorporation of straw. Aggregate stabilities followed the same trend, but differences were not statistically significant.
