Modification of sandy subsoils on EP locations
Aims

To provide further understanding of what is driving responses to modification of sandy subsoils and how soil modification techniques can be improved.

Key messages
  • In sand over clay soils, bleached A2 horizons restrict root growth.
  • Incorporation of clay and organic material into the A2 horizons delivered greater dry matter production but yield results varied.
