Fig. 1. Soil bulk density and volumetric water content {approx}7 d after the last water application in Exp. 1 (Dooley fine sandy loam). Samples were taken centered on the path of the subsoiler. Tillage treatments were: (i) subsoiling with a paratill and secondary tillage with a disk (SSplus), (ii) subsoiling with a paratill (SS), and (iii) not subsoiled (NoSS). Least significant differences are shown where P <= 0.05.
