Truck drivers who apply fertiliser on to farms are being urged to use extreme caution after several recent fatalities and many truck roll-overs.
The New Zealand Groundspread Fertiliser Association says the drought has made farmland across the country hard and dry and conditions are treacherous for drivers.
Its president, Stuart Barwood, says there have been several fatal accidents lately and drivers need to have their wits about them.
Mr Barwood says improvements in technology have allowed fertiliser spreading trucks to venture into territory they would have previously avoided, and that has created problems.
He says drivers should undertake the Spreadmark driver training course to make sure they're following best practice
