Since I posted my original comment, I was interested to find out more. My wife knows a couple of wives of farmer, so she asked 2 on my behalf, and both said they don't do anything like this, and haven't heard of it either. Might depend what crops you are farming, and where?
Even though farms are smaller in the UK, am I correct in assuming that many farmers still practice mono-crop? If they do, then depending on wild pollinators alone is never going to be the best strategy. Crop yields will always increase significantly by introducing farmed bee-hives.
Here is an article I found from the UK Bee Farmers Association https://beefarmers.co.uk/working-with-other-sectors/contract...
It says in the organization even runs a 'National Pollination Service' with a sitting 'Pollination Secretary'.
I think beekeeping is a very interesting industry. I'm sure many people in the UK and the States are probably unaware of these practices and how integral they are to farming.
