Issues (opportunities and constraints) which have the greatest impact on the profitability of growers in the low, medium and high rainfall zones of the Southern Region.
Identified issues and ranking
A total of 131 constraints or opportunities were identified and ranked on risk for grain growers across the low, medium and high rainfall zones of GRDC Southern Region using the area/impact/frequency framework.
The term 'issues' includes constraints and opportunities.
The risk framework used to rank issues -
|Area affected||entire RCSN Zone||4|
|multiple sub-regions within zone||2|
|Impact of issue on profit||high||4|
|Frequency / risk of occurence||every year||4|
|1 in 3 years||2|
|< 1 in 3 years||1|
Common topics identified by RCSNs are summarised below. High value pulse crops, nitrogen management, the risk of losing glyphosate, integrated weed management and concerns around regulation of pesticides were common themes. Issues relating to profit, risk and cost management also featured. There appeared to be a bias toward recent experiences of the past season, including low cereal prices, waterlogging, high yields and greater disease pressure.
