Sorghum is the main summer farming crop grown in Queensland and Northern New South Wales. It's a good choice as a rotation crop due to its high heat and moisture stress tolerance.
Sorghum is well suited for dry conditions, areas with uneven rainfall distribution that may adversely affect the growing season of other crops, and high year to year variation in rainfall and water supplies.
Other advantages to growing sorghum include its ability to be grown on marginal soils and a shorter growing season.
The lower variable cost of sorghum can help growers spread risk by producing another crop at lower cost therefore spreading limited capital across more acres.
