Developing and testing innovative, practical and  reliable methods for incorporating lime into acidic sandplain subsoils locations
Aims

To test modified one-way ploughs as a method of lime incorporation.

Key messages

All cultivation treatments reduced crop establishment significantly below “Nil” cultivation. 

Poor rainfall in September and October 2015 meant that the trial yielded very poorly (~0.5 T/ha), with no significant differences between treatments.

Soil test results are not yet available.
