Trial location(s) Condingup, WA
Investigation of nitrogen dynamics in controlled traffic farming systems (Condingup) locations
Aims

To test the concept of variations in crop nitrogen dynamics in relation to soil compaction during the 2014 season.

Key messages
  • Corresponding to the biomass assessments, the compaction of the Trafficked zone had a notable effect on the crop performance.
  • As a comparison of all sites there was an increase of grain yield of between 18 and 46% of the zero traffic area above the paddock assessments.
