The nitrogen that is deposited in manure, naturally, isn't excessive and is quickly absorbed by the soil and soil life. Runoff from this doesn't pollute.
Now, if you have too much manure (like dairy farms often do) or you use commercial fertilizer, the soil can't absorb it.
Thanks for explaining that better than I did. If cows were out grazing in a pasture their manure and urine is absorbed, as you say.
When they live primarily in confinement and their manure is collected and then sprayed in fields it can potentially cause issues. But the right answer is improved manure management, not less coeds
