Rethinking the Role of Nitrogen and Phosphorus in the Eutrophication of Aquatic Ecosystems

Ashley Smyth, H. Dail Laughinghouse IV, Karl Havens, and Thomas Frazer

Nitrogen and phosphorus are two nutrients that are essential for the growth and survival of plants and animals but are often present in short supply. Both nitrogen and phosphorus are applied regularly through fertilizer to increase the yield of crops needed to feed human populations and for residential and commercial landscaping purposes. This publication contains information for stakeholders, students, scientists, and environmental agencies interested in understanding how nitrogen and phosphorus affect water resources. Major revision by Ashley Smyth, H. Dail Laughinghouse IV, Karl Havens, and Thomas Frazer; 5 pp.

Repensando el papel del nitrógeno y fósforo en la eutrofización de los ecosistemas acuáticos

H. Dail Laughinghouse IV, Ashley Smyth, Karl Havens y Thomas Frazer

Históricamente, las agencias ambientales han buscado mejorar la calidad del agua de los lagos y ríos de agua dulce mediante el manejo de un solo nutriente. El fósforo era el nutriente principal de preocupación en los sistemas de agua dulce y el nitrógeno estaba regulado en los sistemas costeros y estuarios. Investigaciones recientes indican que debemos reducir tanto el fósforo como el nitrógeno para revertir los síntomas de eutrofización en todos los sistemas acuáticos. This new 5-page publication of the UF/IFAS Department of Soil and Water Sciences, written by H. Dail Laughinghouse IV, Ashley Smyth, Karl Havens, and Thomas Frazer, is a translation of SGEF190/SG118, "Rethinking the Role of Nitrogen and Phosphorus in the Eutrophication of Aquatic Ecosystems."
