The impact of stubble treatment on soil nitrogen supply to crops

2016

Trial details

Aims

To determine if differences in early crop growth and development of crops under different stubble management strategies was due to differences in early-season nitrogen (N) supply.

Key messages
  • Soil mineral nitrogen (N) values were low across all sites, which was indicative of the wet seasonal conditions and high nitrogen losses.
  • There were no significant differences in mineral nitrogen values between the stubble treatments due to high variability (likely due to transient waterlogging across the sites).
  • The project has been extended to enable the research to be repeated during 2017.
