Achieving improved water use efficiency through amelioration of hostile subsoils locations
Aims

To provide information for the growing farmer interest in subsoil manuring during the year with data and information on demonstration trials on subsoil manuring on heavy clay and duplex soils where the plant available water capacity at depth is restricted by low porosity, water extraction and root growth.

Key messages
  • Subsoil manuring continues to attract farmer attention.
  • Two new sites will be set up during 2011.
  • On a grey Sodosol at Wickliffe, the manure treatments produced significantly higher yields (11-12 t/ha compared to control).
  • The above average rainfall in the 2010 season resulted in the lack of response to treatments in many cases.
