Aims

To compare no-till with cultivated (conventional) farming systems across 5 crop rotations, with
particular interest in long term;
• yield and gross margins
• weed risks
• disease risks
• nutrition.

Key messages
  • No-till has performed on average 5% higher in yield and increased profits over cultivated farming systems in continuous cropping rotations.
  • Adding cultivation to the system has increased both yield and profit in the 18 month fallow rotations.
  • Thirteen years of continuous wheat has produced the most grain per hectare, closely followed by a wheat–barley–field pea rotation.
