How about energy-related stuff like off-grid electricity, biomass burners, etc.? And water management; water saving, drainage, and so on?
Hedges and fences; maybe someone could talk about hedge-laying or different sorts of hedge management?
Oatridge college? (Have I got the name right?) They have lots of interesting farm related courses; I'm going on a chainsaw course with them in August.
Would SAC be prepared to have a stand, particularly with regard to things like the regulations for pigs and poultry and food production, to show that as officials they're not ogres.
Also soil fertility; how to test it; how to improve it. Maybe the no-till people would have someone up here who could demonstrate their theories.
Forestry Commission! That seems a bit irrelevant but they are playing a big part in the Orchard projects here because orchards don't fit any existing niche. Mike Strachan in Perth comes up with some interesting stuff. He is so enthusiastic; the only adult to have willingly waded through my hillside spiny plum-sucker thicket.
Cairn O' Mohr wines; they are pretty dynamic; developing elder cultivars for elderflower champagne, making cider, holding wacky races...
If the SSPCA have a stand I shall feel obliged to visit it and interrogate them about their grotesque performance at that stud closure up in Aberdeenshire last year, (Tullynessie? something like that?) as detailed on the Horse and Hound forum. But I doubt they'll want to come unless they get free entry.
