There is a "severe shortage" of straw because of an increased demand from power stations, according to the British Hay & Straw Merchants Association.
President of the BHSMA Mike Evison said demand from straw-burning power stations and poor growing conditions are some of the reasons for the shortage.
However, he said most suppliers remained confident of fulfilling contracts, although there is currently very little surplus.
The shortages have resulted in soaring prices since the autumn.
Mr Evison said the overall yield of straw from the last cereal crop harvest was a third down on the normal average.
Records over the last 28 years indicate that there has only been one other severe straw shortage year.
"This was caused by poor growing conditions and the situation was made worse with prolonged wet periods during harvest," Mr Evison explained.
"The consequence of this was that many farmers who usually lay down straw to be baled decided to chop as the likelihood of having it baled quickly was remote.
"Unfortunately, the above situation was not helped by an increasing demand for straw over the last two or three years. There are now four power stations requiring nearly a million tonnes of straw and demand from the continent has steadily increased in recent years.
Mr Evison added: "Many of our members supply straw on contract and most of those attending felt they would for fill their obligations – however they have very little surplus for the usual winter spot trade."
