Enhancing stubble breakdown with additives locations
Aims

The aim of this investigation was to develop a means of enhancing stubble breakdown using nutrient supplements prior to planting of the next crop.

Key messages

A fertiliser additive was applied to standing stubble and compared with untreated stubble. The fertiliser additive was applied with and without a sticker or molasses. There was no significant difference in the amount of stubble dry matter remaining after 6 months i.e. the rate of stubble breakdown was comparable between all treatments. Similarly there were no consistent effects on feed and chemical
characteristics. Addition of nutrients and molasses did not improve intake by grazing sheep.
