Surface irrigation may lead to thick depositional crusts at the soil surface, which can reduce infiltration rate. To break the crust on the sides of the bed near the bottom of a furrow, we developed a torpedo-shaped, winged cultivator. Field experiments were conducted on a tomato crop at UC Davis on Yolo loam soil during the summer of 1992. Breaking the crust with the device increased cumulative infiltration significantly, by almost 30%.
