The Ravensdown fertiliser co-operative says there may be some softening in fertiliser prices on the horizon, following months of record highs.
The commodities boom has driven up demand and prices for fertiliser.
The cost of urea for example, rose from $700 six months ago to more than $1100.
But Ravensdown chairman Bill McLeod told this week's annual general meeting that sulphur prices have dropped by $US300 per tonne.
He said prices of phosphate rock and urea were also falling.
