Comparison of tillage methods for lime incorporation locations

Using tillage to incorporate lime improves the rates of reaction and increases subsurface pH soomer than spreading lime on the surface alone.

Key messages
  • Plant emergence was greatest in the offest disc treatment and lowest in the mouldboard plough treatments. Depth of sowing is critical and difficult to control on soil ameliorated soils.
