Increased capture and use of deep subsoil water We observed that subsoil manuring enabled the crop roots to extract more deep soil water from the subsoil layers in dry years... We believe that the improved ability of the canola crop on subsoil-manured plots to establish, and then withstand the heavy winter rainfall at the Penshurst site in 2010 (Table 3), compared with the commercial crop, resulted from better aeration in the subsoil... There was no need for the crop to extract water from the subsoil, as there was ample soil water in the topsoil...

The project will determine the effectiveness of subsoil manuring across the High Rainfall Zone in SW Victoria... The project is expected to demonstrate that subsoil manuring will result in large increases in grain yield at a range of sites, and over a number of seasons, and that these continuing increases from a single intervention, will be profitable... The expected outputs will be the knowledge (i) of the magnitude of grain yield increases that result from subsoil manuring (ii) that the yield increases continue with successive crops for a number of seasons, and (iii) that the practice will be profitable...
