hostile subsoil

Catalogue: GRDC Final Reports
A Subsoil Reference Manual produced as part of this project provides important information in a relatively easy to follow format... Possible reasons underlying the lack of response to subsoil amelioration in the current project were assessed in a glasshouse trial using intact cores (which maintained the chemical/physical integrity of the soil profile)... Significant correlations between different subsoil factors were found, supporting observations in a previous study that was limited to a single district (Nuttall et al. 2003)...

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...
