Data from: "Understanding the effects of grazing and prescribed fire on hydrology of Kentucky bluegrass–dominated rangelands in the northern Great Plains”

Rainfall simulation experiments and hydrophobicity measurements with water drop infiltration time and molarity of ethanol droplet tests were conducted at three locations all within the same ecological site in the northern Great Plains. Rainfall simulation experiments were performed on 24 large plots (6 × 2 m) at 63.5 mm h–1 and 127 mm h–1 intensities and on 16 small plots (0.7 × 0.7 m) at 63.5 mm h–1 and 103 mm h–1. Rainfall was maintained on the large plots until 10 minutes of steady-state runoff was measured or for a maximum of 30 minutes in the absence of runoff, while on the small plots, rainfall duration was set at 25 minutes. The soil layer was divided into four strata (litter, thatch, root mat, and mineral soil), which were physically separated for their hydrophobic behavior in laboratory and field water drop penetration tests and molarity analyses.
