Tillage and fertilization practices affect water infiltration. A long-term study at Pendleton, OR compared three tillages (plow, disk, and sweep) since 1940, and two rates of N (45 and 180 kg/ha) since 1962. Infiltration rates for plow, disk, and sweep were 17, 14, and 16 mm/h, respectively. Rates for the low and high nitrogen were 9 and 22 mm/h respectively. Results also indicate that surface sealing and soil frost are probably more important than tillage pans for infiltration. Residue cover eliminates any tillage effect on infiltration, while fertility is important in producing more crop biomass.
