Subsoil manuring: an innovative approach to addressing subsoil problems targeting higher water use efficiency in southern Australia locations
Aims

To report on subsoil manuring: an innovative approach to addressing subsoil problems targeting higher water use efficiency in southern Australia.

Key messages
  • Subsoil manuring resulted in consistent grain yield increases across the network of sites in the HRZ of Victoria. In years with drier finishes, the yield of the commercial control crop was constrained due to water deficits during grain filling, while the subsoil manured crops were able to access additional subsoil water. Thus, these crops were not constrained and significantly higher yields were achieved.
