You wont get £26. Nothing to do with wheat and exchange rate. Entirely to do with haulage. For 2009, we will be subsidising haulage to the tune of £2 a ton, and that is a 35 mile haul, not like taking it from York to Newark. So thats it down to £24/t nett. As I have said, excluding SFP but including rent, it costs about £500 an acre to grow, so at £25 a ton you need 20t/ha to break even. At the BS target of 70t/ha, thats £200 an acre profit pre SFP.
I would expect light land farmers to grow, especially if they havent got irrigtaionfor spuds/roots. For us, its tricky as so much rests on getting it in the ground promptly.
Adding in the cost of a potentially less rewarding wheat crop behind it, there are a lot of downers.
Still, at 70t/ha = roughly £200/ac profit, plus your SFP if you are counting that as farming income it pays well. For anyone routinely getting 50t/ha or lower, get rid. At that beans, peas, linseed, rape, wheat etc all pay better. And you can put your combine cost over those extra acres.
