Reducing the impact energy of sprinkler droplets through irrigation management should minimize surface soil aggregate breakdown and seal formation while maintaining infiltration rates. From 1997 through 1999 in southern Idaho, we quantified sprinkler droplet energy effects on infiltration and near-surface hydraulic conductivity measured under tension after crop stand establishment. The treatments were droplet energies: 0 or 7 J kg
