To develop a means of enhancing stubble breakdown using nutrient and microbial supplements prior to planting of the next crop.
Five different stubble additives were applied to standing stubble: commercial digestor with and without microbes, a Uni of Tas experimental brew with and without a sticker and ammonium thiosulphate. While there was a significant increase in fungal colonisation for some of the treatments there was no significant difference in the amount of stubble dry matter after 6 months i.e. the rate of stubble breakdown was comparable between all treatments. Differences in digestibility and fibre will be further evaluated.
