Three trials were implemented in 2010 in the Mackay area to study the impact of different GCTB levels on the weed population and cane yield. Cane yield was higher when grown with a GCTB compared to bare soil. There was no significant yield difference between trash treatments, but there was a trend in favour of the thicker trash levels. The management of broadleaf weeds and grasses improved with an…
