Potassium strategies for the wheat lupin rotation - 2013 locations
Aims

To determine the optimum (K) fertiliser strategy for the wheat lupin rotation.

Key messages
  • Plant testing should be used as a guide to better K fertiliser decisions.

Other trial notes

Treatments correspond to those in NAG_2011_1 2012 was a breakcrop year 2013 wheat yields were limited by very dry growing conditions. K had no effect on grain quality. Water repellence and/or subsoil compaction may be limiting yield potential and therefore the requirement for K fertiliser
