Volatility on world fertiliser markets and the decline in the New Zealand dollar has brought with it a mixed bag of price changes for farmers.
Ravensdown said urea prices had fallen by $14 to $575 per tonne while superphosphate rose $4 to $320 a tonne and di-ammonium phosphate (DAP) is up by $50 to $865.
"While recent months have seen a general decline in the price of urea, it has been volatile with a recent firming particularly due to demand from India and Pakistan," the farmer-owned co-operative said.
Prices, it said, were now expected to stabilise at current levels.
"The global decline in urea prices has offset a significant fall in the US dollar, however for other key farm inputs like superphosphate and DAP the change is a net increase."
