Why should I be concerned?

Most Nebraska farmers apply some source of plant nutrients to help improve their crop production each year. Nutrients come from applied chemical fertilizers, manure or sewage sludge, and soil organic matter or legumes. When nutrients move off site or leach out of the root zone, they can pose a threat to the environment and the water we drink.
