Contributor Central West Farming Systems
Trial location(s) Minlaton, SA
Paddock yield and seeding depth optimisation locations
Aims

To report on paddock yield and seeding depth optimisation.

Key messages
  • Seeding depth uniformity is influenced by both seed placement quality within the furrow and the consistency of added soil cover
  • Many machinery design and operating parameters affect the uniformity of seeding depth across a paddock
  • Deep sowing (eg. beyond 50-6omm) can significantly affect crop emergence and final grain yield
  • Many paddock situations can soon suffer a 5-10% yield loss as a result of inadequate seeding depth, with more extreme situations suggesting possible yield penalties of 15-20% or more.
