Subsoil amelioration – results from year two locations
Aims

To investigate effects of soil amelioration methods on subsoil constraints and the benefits to grain yields in the Mid-North of SA.

Key messages
  • Grain yield at Hill River was increased on two soil types by 12% and 33% through the addition of soil amendments to the surface or subsoil.
  • There was no yield difference between applying amendment to the surface or subsoil in 2016, except at one of the seven sites sown to lentils.
  • There was little difference between applying large rates of synthetic fertiliser or applying 20 t/ha chicken litter.
