Grain Growers Cut Fertiliser Use Amid Rising Costs

 A new Grain Producers SA survey has revealed South Australian grain growers are cutting fertiliser use and tightening spending as soaring input costs continue to pressure farm profitability ahead of the 2026 season.

The GPSA Seeding and Seasonal Outlook Survey collected responses from 384 growers across the state and found confidence remains fragile, averaging five out of ten despite improved rainfall conditions in many cropping regions.

The survey showed wheat and barley plantings have fallen slightly this year, while lentil production continues to increase as growers shift toward lower-input crops.

More than 70 per cent of respondents say they have already reduced fertiliser applications to combat rising costs, while almost all surveyed growers expect fuel and fertiliser prices to exceed budget forecasts this season.

GPSA Chief Executive Officer Brad Perry says the survey data highlights the growing financial pressure facing producers, with many businesses forced to alter rotations, reduce crop area or cut nitrogen applications to manage costs.

He says fuel, fertiliser, freight and finance costs have all risen sharply while grain prices have softened considerably, leaving many growers concerned about their ability to return a profit this season.
