Grain sorghum is Australia’s most important summer crop both in terms of area sown and quantity of grain produced. The area sown to grain sorghum has consolidated to around 600,000-700,000ha despite droughts, with two thirds of that area produced in Queensland. In Goonoo approximately 3,300ha was sown in sorghum, using both irrigated and zero-till systems. I had never seen this crop before arriving in Goonoo, but soon after my arrival I was part of the harvest crew. The feedlot require the moisture content for sorghum to be a maximum of 13.5%. Sorghum is naturally high in protein and is a vital ration constituent for the feedlot. Another unique feature of the crop is the genetically modified (GM) seed used.
