  • Fertilizer costs have rocketed since the war in Iran choked off deliveries from Gulf nations

CANBERRA: Australia’s upcoming wheat harvest will be the smallest in three years, as high fertilizer costs and dry conditions in some areas reduce planting ​and yields, the government said on Tuesday.
Australia is a major exporter of ‌wheat and other crops. Lower output would reduce global supply, putting upward pressure on prices that reached two-year highs last month due to crop losses in the US.
Australia should ​reap 26.7 million metric tonnes of wheat later this year, the ​Australian Bureau of Agricultural and Resource Economics and Sciences said in a quarterly crop report.

FASTFACT

Australia is a major exporter of ‌wheat and other crops. Lower output would reduce global supply, putting upward pressure on prices that reached two-year highs last month due to crop losses in the US.

That would be around 9 million tonnes less than last ​season and roughly 8 million less than the average over the last five ​seasons, according to its data.
Fertilizer costs have rocketed since the war in Iran choked off deliveries from Gulf nations. High prices will likely cause farmers to fertilize less, reducing yield potential, ​said ABARES, a part of the Agriculture Ministry.
Meanwhile, large parts of Australia’s east ​have had months of low rainfall. Widespread rain during May improved crop conditions, but the ‌country’s weather bureau still predicts an El Nino and below-median rainfall in the coming months.
“It will be crucial that adequate and timely supply of fertilizer is available and adequate rainfall is received to meet current yield projections,” ABARES said.
ABARES estimated that the ​amount of land planted ​with wheat would fall 12 percent from last season to 10.9 million hectares, the least since the 2019/20 season.
Planting of barley — which requires less ​fertilizer than wheat — is set to increase 4 percent from last ​season to 5 million hectares, but production will still fall 15 percent to 14.1 million tonnes, ABARES said.
The area planted with canola — which needs plenty of fertilizer but is more valuable than ​wheat — should fall 6 percent to 3.5 million ​hectares, but the harvest will be 20 percent smaller at 6.2 million tonnes.
Australia’s sowing period is just wrapping ​up and harvest is due toward year-end.
