Fig. 8. Soil water content of the top 1.83 m during and after simulated rainstorms on the Williams loam (Exp. 2). Soil water measurements taken immediately after a 3-h simulated rainstorm are labeled Day 1, Day 2, and Day 3. Tillage treatments were: (i) subsoiling with parabolic subsoiling shanks and secondary tillage with sweeps (SSplus), (ii) subsoiling with parabolic subsoiling shanks (SS), and (iii) not subsoiled (NoSS). Least significant differences are shown where P 
0.05.
