The phosphorus dynamics of dryland cotton production require further elucidation, particularly the role of residual fertiliser P and mycorrhizal infection in yield.

UNE 1501 – ‘ Phosphorus availability in raingrown cotton’, was conducted at ‘Colonsay’, via Brookstead, on the Darling Downs in Queensland, at a long term nutrition site, owned and maintained by Incitec Pivot for 30 y

In this investigation we have identified that approximately 30% of the sites in both years investigated are showing issues at depth with respects to root development and / or irrigation infiltration.

The broad aim of the ‘UNE/CRDC Cotton Course’ has been to provide students with the necessary scientific and practical skills for sustainable cotton production.
