Just to clear up a few of the farming misconceptions here.
OP: what do you mean by a silage tank? Silage is grass that has been cut into small pieces and is then stored in ‘clamps’, usually three-sided structures with black plastic and old tyres on the top. The grass is effectively picked to preserve it and proper silage doesn’t smell bad, rather sweet and fresh. Silaging usually happens in May/June in the UK. Now, a slurry tank on the other hand is one that contains slurry, which is not the same thing as silage.
Hirpies: ‘probably slurry when fields are cut for silage’ – slurry has nothing whatsoever to do with silage. Slurry is semi-liquid manure and farmers don’t tend to spread that when they’re silaging…
Origami: ‘Farms can get very messy if the owner isn't the tidy sort, and under planning laws, they can leave equipment lying about, they can erect barns, build cattle sheds, site slurry tanks, store silage under tires, all without any consultation if it is in the course of their livelihood.’ I don’t know where you get this idea from. Farmers have to comply with planning laws just like anyone else. They certainly can’t build cattle sheds without proper planning consent.
WellErrr: ‘Farming will be far better off if we vote out, I wouldn't worry about that. And most farming land is green belt and won't be built on.’ Disagree that we will be better off if we leave the EU. And to say that most farming land is green belt – haha. Green belt pretty much only applies to fairly small areas of land surrounding urban areas. Most land in the UK is absolutely not green belt – only 13% of land in the whole of the UK is green belt.
Info on green belts
I live on a beef/mixed farm (farmer's wife) and the flies and smells can be a nuisance in the summer. Dairy farms tend to be worse for those things, but I'd still rather live here than anywhere else.
