CORE LABORATORIES

FROM THE CHAIR


The Soil and Water Science Department (SWSD) faculty and students use a wide range of
analytical and field instrumentation in their research programs. To maximize the use of these
analytical instruments, groups of faculty established several core laboratories in the
department with the objective of sharing instrumentation and avoiding duplication of facilities.
The instrumentation in each core laboratory was purchased by select faculty through their
grants and contracts with some matching support from state funds. Instrumentation in these
laboratories are primarily used by these faculty and by their graduate students. In addition, at
a minimal cost, the instrumentation in each of these core laboratories are now made available
to other SWSD faculty and to those outside the department. Details of costs associated with
the use of these laboratories can be obtained from the coordinator of each laboratory. A brief
description of the core laboratories is presented in this newsletter.
Here are few highlights since the last newsletter:
Steve Bloom, Senior Chemist retired after 23 years of dedicated service with the department.
For the past four years, Steve worked in the GIS Research Laboratory. Prior to this assignment,
he worked with the Soil Physics group. We thank Steve for his outstanding service to the
department.
L. Rex Ellis has been appointed as an Assistant Research Scientist in the Environmental
Pedology program. Rex will conduct research on subaqueous soils.
Todd Osborne has been appointed as an Assistant Research Scientist in the Wetlands program.
Todd will conduct research on biogeochemical cycling of nutrients in wetlands and aquatic
ecosystems.

In Memoriam


William G. Blue, 82, Emeritus Professor of Soil and Water Science
Department at the University of Florida, died in Gainesville, Florida on
July 12, 2006.
He was born in Poplar Bluff, Missouri on November 7, 1923. He enrolled in
the University of Missouri in 1941. During World War II, he served as a
reconnaissance sergeant in the 78th Infantry Division in Europe and was
awarded a Purple Heart. After the end of war, he went back to the
University of Missouri, and received his B.S. in agriculture in 1947 and
i advanced degrees in Soil Science, M.S. in 1948, and Ph.D. in 1950.
Dr. Blue was appointed as an Assistant Biochemist in 1950, by the Florida
Agricultural Experiment Station at the University of Florida, working on
soil fertility problems in forage production. Later, his research expanded
to other areas, including the characterization of the action of anhydrous
ammonia in coarse textured soils and its relation to soil chemistry and
microbiology as well as plant response. He also studied the nitrogen
efficiency of forage plants in poorly drained coarse-textured soils and
potassium and phosphorus effects in coarse-textured and highly weathered
soils. In 1964, whole agricultural programs at the University of Florida were reorganized and the Institute of
Food and Agricultural Sciences was established. The College of Agriculture, Agricultural Experiment Station, and
the Agricultural Extension Service became parts of the Institute. The faculty and their titles in these units were
also integrated. Dr. Blue, then a professor, was asked in 1968 to teach a graduate course in soil fertility. From
that year to his retirement in 1989, he had taught a total of approximately 400 students. He also served as the
advisory committee chair for 17 Ph.D. and 15 M.S. candidates in the Soil and Water Science Department. Many
of them came from overseas, including Asia, South America, and Africa. He was also a member of another 80
graduate committees in Soil Science and other departments in the Institute. He published extensively and
authored and coauthored approximately 200 scientific papers. He was deeply involved in University
international agricultural programs. He was in Costa Rica from 1958 to 1960 as a pasture agronomist and in
1985, he had a two-year assignment as a research and extension advisor in Cameroon, Africa. He also had
several short oversea assignments.
He was a member of ASA and SSSA for over 40 years and was elected a Fellow of both societies. He served as
Associate Editor for the SSSA Journal. He was a member of Sigma Xi, Alpha Zeta, Gamma Sigma Delta, and
Alpha Gamma Rho. He was a member of the Florida Soil and Crop Science Society of which he was president in
1961 and editor of its proceedings.
He retired from the University of Florida in 1989, after 39 years of a successful and outstanding career. He was
respected by his colleagues and loved by his students and those who worked under him. He is survived by his
wife of 59 years, Bernice, and three daughters, Carol Blue Garcia, Jane Blue Marquez, and Cynthia Blue Russell,
as well as seven grandchildren.
