Sulphur management in a three year rotation locations
Aims

To establish product, rates and timings suitable to achieving the most economic return for managing sulphur deficiency.

Key messages
  • The addition of sulphur increased wheat grain yield at both trial sites.
  • Grain yield at the clay loam site was consistent for all of the sulphur rates, sources (gypsum and SoA) and application times tested
  • In contrast, there was variation in grain yield for the sulphur treatments tested at the sandy dune location due to the poor nutrient holding capacity of this soil type.
