Stubble management practices in HRZ to minimise the requirement of burning and potential for yield and soil benefits locations
Aims

All four trials were aiming to evaluate what alternative stubble retention practices can be implemented into the cropping system, without
incurring yield penalty or significant cost to the grower.

Key messages

No real conclusions can be drawn from 2005 data, although the use of scratch tillage at the Inverleigh and Mingay sites showed some promise, but did come at a financial cost if implemented on raised-beds.
