Could someone please explain to me how this works as I don't understand it
Farmer takes 80 acres @ £250/acre on 5 year agreement.
It's approx 7 miles away and he plants it with Winter Barley with current price just under £100/ton
Plough based system.
Am I missing something here
No, you are correct. He won't make anything out of it & will be a busy fool. @le bon paysan 's post sums it up nicely.
The annoying thing about this is that some of these speculators are so ignorant of what it costs to grow a crop that their substantial balance sheets will permit them to carry on doing this for the entire duration of the agreement. If they do wake up or the bank manager reins them in then there will be another eager young buck ready to take their place. They will have been taught at ag college that they can farm so much better than the old boys & they need more land to make room for them at home on the family farm anyway.
There will be jam tomorrow - the Chinese will have a couple of disaster harvests & repeat the Great Russian Grain Robbery, just like the history books wrote in the '70s.
