In 12 months the price of commonly used fertilisers essential for Australia’s $43 billion cropping industries has increased by as much as 230 per cent.

Key points:

  • Fertiliser prices have risen an extraordinary amount over the past year
  • An increase in energy costs is behind the price rise
  • Australian grain growers are looking for alternative fertiliser options

Grain farmers looking to sow summer or winter crops are bracing for a massive increase in production costs and some are looking for alternative options to synthetic fertilisers.

Thomas Elder Markets commodity analyst Andrew Whitelaw recently analysed fertiliser prices and he was shocked by what his modelling revealed.

“If we look at urea and [diammonium phosphate], those prices this time last year were around about $400 to $550 a tonne landed in Australia,” he said.

“Now we’re talking, for both of them, above $1,400 a tonne.

Rising cost of synthetic nitrogen

Mark Seymour, a veteran crop scientist specialising in pulses in Western Australia, said the rising cost of synthetic nitrogen could lead to farmers investigating whether a pasture or pulse crop could fit into their systems to naturally fix nitrogen into the soil.

“No one thing will fit everyone,” he said.

“Some people may just reduce their inputs and grow the same enterprise; there’s talk of more fallow in the areas that do fallow well and for the areas that do legume relatively well, you might expect more go into those and reduce inputs into the legume phase.

For Mark Roberts who farms at Cascade, about 100 kilometres north west of Esperance, grazing pulses make up 20 per cent of his land use. 

The mix of woolly pod vetch and serradella helped not only feed his flock of sheep, but also added valuable organic nitrogen to his soils for following with canola or cereal crops. 

He estimated his paddocks, which were planted to vetch then wheat saved him about $250 per hectare when compared to a paddock that was planted to wheat after canola and therefore needed additional synthetic nitrogen.

Reducing fertiliser rates

Murdoch University professor John Howieson said legumes were key to reducing fertiliser bills and increasing overall profit.

He said a new variety of pink serradella called Fran2o was proving particularly good at organically fixing nitrogen in a range of soils.

“I’m excited because it’s so well adapted to the Wheatbelt conditions,” he said. 

Professor Howieson said data from 40 experiments over the past four or five years showed cereals grown after seredallas, such asFran2o or Margurita, were able to access significant quantities of fixed organic nitrogen from the soil, so much so the cereals did not respond to added synthetic nitrogen.

A Grains Research and Development Corporation (GRDC) project is assessing the economics of how the changing phosphorous price altered the optimal rate of application for maximum net return in wheat production. 

Researcher Craig Scanlan said so far the study had found the greatest influence on the optimal application rate for P fertiliser was the yield response in tonnes per hectare.

Mr Scanlan urged farmers to use soil test data and plan the most profitable rates for their paddocks.

Prices to remain high 

Analyst Andrew Whitelaw said the huge price hikes in fertiliser all boiled down to one factor: high energy costs.

“Synthetic fertilisers are made using energy,” he said. 

“In Europe it’s generally natural gas, in China it’s coal and what we’re seeing is those [coal] prices have gone just absolutely through the roof.

“I just don’t see it [fertiliser prices] falling massively. We don’t see it getting back into the A$800 or less mark, by the time we have to buy. We’re liable to have high prices for Australia right through to our seeding period.”
