Farmers are worried about high input costs and their finances, according to the Ag Economy Barometer published by Purdue University and sponsored by the CME Group.
The barometer for current conditions is down to its lowest level in 18 months.
For the first time the survey included questions about artificial intelligence and 52 per cent see no benefit for their farm. Increasing yields and reducing labour costs were cited as the main potential benefits.
About 85 per cent indicated they favour free trade and 43 per cent said they expect exports to increase over the next five years.
