Cusco, say you offered him £200 an acre which I suspect is more than he could ever make cropping it with cereals based on grain prices over the last few years even when counting the subsidy ( which he would lose if the land was not in production) you would have to provide assurances in regards to liabilities and insurance etc. the issue may be why would a non flying farmer want to bother giving someone else access , especially for aircraft, to his multi million pound property for a grand or 2. He'd probably feel it's more hassle that it's worth.
