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.

UF/IFAS researchers are re-examining nutrient guidelines for Florida citrus

Mike Loizzo

UF/IFAS researchers are updating nutrient guidelines for Florida citrus, since current nitrogen and phosphorus recommendations are based on healthy citrus trees before citrus greening disease or HLB.

Members of UF/IFAS department of soil, water, and ecosystem sciences contribute to book on sandy soils

Mike Loizzo

Anyone working the land in Florida is aware just how sandy the soil is throughout the panhandle and peninsula. Even the official state soil is Myakka fine sand. So, it is not surprising the first book solely focused on sandy soils includes authors from the UF/IFAS department of soil, water, and ecosystem sciences (SWES). With […]
