Impacts of crop management strategies on nutrient stratification and soil test interpretation locations

To investigate two management strategies applicable to the Mid-North region that could influence nutrient stratification.

Key messages
  • Concentrated chaff distribution had no significant impacts on nutrient stratification either horizontally or vertically across the landscape at three sites.
  • Chicken litter applications appear to complement traditional chemical fertiliser applications by increasing P availability.
  • All nutrients assessed were well above established critical levels and there was a tendency for all nutrients to be concentrated at the surface (0-5 cm) regardless of the known differences in mobility between N, P, K and S.
