Isn’t one of the issues with the Dutch government attempting to shut down a lot of farmers that the cows are creating too much ammonia? Send that cow pee to Germany.
Here in the Ozarks the ground is so poor the only way to make it fertile is to raise tens of thousands of chickens, then used the manure on the fields.
If you have ever been in a large chicken house in the summer you will be choked and tear up by the ammonia produced by the chickens.
