well then, jim, use the term "inactive landowners" not farmers.
I suggest the "horny hands test" for activity, or
the same criteria as the inland revenue use could be applied, ie inspect the farmhouse, does it have an aroma of sheep doo doo, deisel, oil, etc round the back door? does the office look like a twister has been through? are there piles of wellies, oilskins etc?
Does the pickup look like the one clarkson blew up on telly?
is the garden immaculate,? or does it get power harrowed once a year and toppped by tractor?
You do realise that if you remove the ability to clsaim on naked acres, you put the lairds back in full control of tenants sfp, with resultant rent rises inevitable.
The resultant drop in the capital value of sfp will remove the current underpinning of tenant
farm overdrafts, so look forward to a flood of displenishing sales , and you will get more land to farm thasn you can handle.
