About the Citation Classics

Citation Classics is a new content series developed by the UF/IFAS Research Dean's office to highlight faculty-authored publications that have made substantial impacts in the scientific community and the world. This page will be updated throughout the next several months with additional, highly cited papers.

If you would like to nominate a paper for recognition, please email Mary Anne Sanders at mary.sanders@ufl.edu.

Conley D.J. et al (2009). Controlling eutrophication: nitrogen and phosphorus. Science, 323:1014-1015

Algae washing up on beach

The late Karl E Havens published more than 150 peer-reviewed journal articles throughout his 35-year career in aquatic research. His research specialty was the response of aquatic ecosystems to natural and human-caused stressors, including hurricanes, drought, climate change, eutrophication, invasive species and toxic materials.

In 2004, he joined the UF/IFAS enterprise as the Chair of the School of Forest Resources and Conservation's Fisheries and Aquatic Sciences program. Four years later, he became the Director of the Florida Sea Grant College program.

A paper he co-authored and published in Science titled "Controlling eutrophication: nitrogen and phosphorus" had been cited more than 2,000 times! According to Google Scholar metrics, this paper gains traction each year with the number of citations per year continuing to grow, showing its relevance and importance to the scientific community.

Dr. Havens passed away in April 2019, and this paper is just one example of the tremendous body of work that he left behind for the benefit of all.

Jones J.W. et al (2003). The DSSAT cropping system model. European Journal of Agronomy, 18:235-265

In 1983, UF/IFAS researcher James W. Jones was asked to contribute to a new USAID initiative on the use of agricultural systems to determine how to transfer research results from one data set containing weather, soil, and socioeconomic conditions to others with differing conditions. He collaborated with soil scientists, agronomists, statisticians, plant pathologists, and economists to develop the Decision Support System for Agrotechnology Transfer (DSSAT). Since then, the DSSAT has expanded from a basic system with only four crops to a dynamic model with 42 crop species (version 4.6).

This work was published in 2003 by Dr. Jones and UF/IFAS researchers Gerrit Hoogenboom and Kenneth Boote, along with contributing authors from other universities. The paper titled “The DSSAT cropping system model” was published in the European Journal of Agronomy and has been cited more than 1,700 times!

The paper explains how the DSSAT was re-designed in a modular structure where components separate along scientific discipline lines and are structured to allow easy replacement or addition of models. It is also designed for incorporation into various application packages. In this paper, the authors describe the benefits of the new design.
