Openfield urged farmers to exploit depressed fertilizer prices, even as potash giant Uralkali heralded an end to the tumbling in potash values, forecasting a "definite rebound" in 2014.
Openfield, the UK farm co-operative, said that the fall in retail prices of nutrients to their lowest since the depths of the global economic crisis represented a "good opportunity" for farmers who have skimped on fertilizer applications to play catch-up.
"Phosphate and potash markets have seen significant price falls over the past 12 months and are currently trading near to the lows of 2009-10," said Adam Thwaites, a regional fertiliser manager for Openfield, citing a "lack of recent demand" as behind the declines.
"For those who have taken a phosphate and potash holiday in recent years, the current prices represent a good opportunity to redress the balance and avoid depleting soil reserves further."
The comments echo an assessment last week from Gleadell, the UK grain and fertilizer merchant, that for potash, "with market at a three-year low, now is a definite opportunity to buy".
And, separately on Thursday, Russian potash giant Uralkali, whose break-up of the Belarusian Potash company cartel has been central to the tumble in values of potash and other fertilizers, forecast that the market would bottom out early 2014, when a new supply contract with China was expected.
Terms agreed with China, the top potash importer, tend to set benchmarks for other contracts.
After this early-2014 nadir, "there will be a definite rebound", Oleg Petrov, the Uralkali head of sales and marketing, said.
Mr Petrov also rowed back from a caution made at the time of the BPC split that potash prices could fall below $300 a tonne, representing a fall of 25% or more.
While failing to make a forecast for the level at which prices will fall too, he flagged a price or about $330 a tonne for potash delivered to the Chinese border as a "guideline" level.
Uralkali revealed a rise in production to 2.7m tonnes in the July-to-September quarter, up 300,000 tonnes quarter on quarter, and 100,000 tonnes year on year.
The group said that it would, after leaving the strictures of the BPC, lift volumes in an effort to offset in tonnage what it would lose in lower prices.
