Stubble management is a significant issue in Western Australia particularly in the high rainfall zone, where it is not uncommon for cereal yields to reach over 7 t/ha with the resulting stubble loads being up to 10 t/ha. This is a high amount of stubble residue left post harvest and is an increasing concern for local growers due to poor establishment of following crops, nitrogen (N) tie-up, disease carryover issues and seeding operation inefficiencies such as, blockages, hair pinning, poor soil throw and bulldozing. As a result, plant establishment has become increasingly difficult, particularly Canola establishment.
