Aims
To improve water use efficienes of crops and pasture by reducing the soil constraints that impede root growth.
Key messages
Spader generally produced a positive yield response (grain and biomass) on sandier soils that had previously been clay spread and /delved.
The inclusion of organic matter prior to spading generally improved the level of response to spading.
Know your soils that you are spading; (not recommended on shallow red loam soils over clay where there is a sodic A2 horizon)
