Long term cropping systems trial locations
Aims
  • To compare the performance of three seeding systems and two nitrogen strategies.
  • This is a rotation trial to assess the longer term effects of seeding systems and higher fertiliser input systems on soil fertility, crop growth and grain yield and quality.
Key messages
  • There was no significant difference between seeding systems or level of nutrition on grain yield or oil content.
  • Soil available N was the same for all seeding systems pre-seeding however, the no till treat had released more available soil N.
  • In-season more available N was measured in the high nutrition treatment compared to the medium.
