My cousin works as a farmer's hand in the Netherlands. He had an interesting anecdote about liquid manure. They used to spray it over the land, but people living nearby started complaining about the smell, so they started injected it underground. They found that yields improved after that.
They stored the liquid manure in a big bag. I stood on it, it was a bit like a water bed.
