Liquid nitrogen fertilizer spill kills nearly 750,000 fish in Iowa river, officials say
Hundreds of thousands of fish were killed earlier this month in a nearly 50-mile stretch of the East Nishnabotna River to the Missouri border due to a fertilizer spill in Iowa, state officials said.
It is not the liquid nitrogen you are thinking of. It was either 28 or 32% nitrogen which I believe is made from urea and is very saline. I have used the 28% on my farm. It is roughly 3# of nitrogen in each gallon of suspension.
