Fertilizer shortage could nearly halve Western Australia’s grain harvest

Grain production in Western Australia could drop sharply without sufficient supplies of nitrogen fertilizers, particularly urea. Despite favorable rainfall and an early start to planting following recent rains, the 2026/27 crop is now facing significant risks.

Industry estimates suggest that, in the absence of adequate urea, the grain harvest could fall from a record 27 million tonnes in the previous season to around 15 million tonnes. This would represent a decline of nearly 45%, dealing a major blow to the region’s agricultural sector.

Western Australia is the country’s largest grain-producing and exporting region, meaning fertilizer shortages could have wide-reaching impacts on the broader market. The lack of nitrogen is especially critical, as it plays a key role in determining crop yields.

The shortage is largely attributed to disruptions in global supply chains caused by escalating tensions in the Middle East. Australia relies heavily on urea imports from the Persian Gulf, where shipments are currently constrained due to maritime security risks.

The situation is further complicated by limited fuel availability, which is essential for field operations during planting. Meanwhile, industry bodies are preparing updated forecasts for planted area and production, which are expected to clarify the scale of potential losses in the coming weeks.
