Trees to plant

[farmerfred86]

IF you're being paid for 5 years to keep it as no- or low-input grassland of course you can't plant trees on it, read your handbook, but how many years do you have left?

Of course not... But we only have a year left so Im wondering what options we have for a field that it's too boggy and overgrown for cropping. Not sure if it's better in a scheme or weather we should simply clear what we can and plant a hybrid willow?
