well the farmers for the last couple of years have been arguing that they want this green rate devalued er to try and bring it line more with the market rate er and what this would do would er increase our guaranteed prices in this country and in fact on friday this happened er the green rate was devalued by 60%. er and so i've done a few calculations er and for the farmers that are listening and er may understand this er if he was selling his grain in november 89 he would be getting about £99 a ton, whilst if he sells it in november this year he'll be getting £110 a ton.
