Just read all 77 pages of the Basic Payment Scheme Guide to Cross Compliance in England 2015 (yup, I'm the one). I see if you're in an NVZ you must not spread fertiliser or manure "if a field is waterlogged, flooded, snow-covered, or has been frozen for more than 12 hours in the previous 24 hours". So, you look out of the window in the morning and the weather's terrible and, rather than rush to de-ice the drinkers or cart hay to the sheep and cattle, you think "Ooh, a perfect day for muckspreading!"? Have these people ever seen a field?
I also see that English Heritage has been renamed Hositoric England - bet that kept Her Majesty's Stationery Office busy for a few weeks reprinting all the letterheading and compliments slips.
