Black Root rot (Thielaviopsis basicola) BRR is a major threat to cotton production in southern and central NSW. It has a wide host range of more than 230 species of plants (Pereg 2013).

Soil compaction is a hidden and continuing constraint to cotton productivity due to increasing size and weight of equipment and is estimated to be in the order of >$30M in lost revenue.

Over the past 25 years soil carbon sequestration has been assessed in many experiments.

Archived soil samples from 0-30 cm that had been collected between the 1993 and 2013 from seven different experiments run by the NSW Department of Primary Industries in Queensland and New South Wales were analysed for

For sustainable cotton production, Australian cotton farming systems need to promote and optimize soil biological functions to by improving nutrient use efficiency, increasing biological nitrogen inputs, reducing dise
