Low Rivers Increase Fish Kill Risk from Fertilizer
DES MOINES, Iowa (AP) - State environmental officials are asking farmers to be extra careful when applying fertilizer and manure to fields after harvest this year because the state's rivers and streams are running low, which means even the smallest of spills can kill fish.
Fisheries Biologist Scott Grummer says he is already seeing manure and fertilizer application on some fields and advises farmers to allow more distance between application areas and vulnerable spots like streams and tile intakes this fall.
The Iowa Department of Natural Resources has already investigated four fish kills this month.
In Lyon County cow manure killed more than 500 fish in the Little Rock River and hog manure seeping into Big Cedar Creek in Pocahontas County killed catfish and smallmouth bass valued at $20,000.
