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:

CORE LABORATORIES PAGE 2
Soil Chemistry, Environmental Hydrology Et Soil Moisture Labs
Soil Chemistry Laboratory
The Soil Chemistry Laboratory was established to provide basic soil chemical -
analyses to students and faculty in the SWSD. Instrumentation consists of a Varian ,
Fast Sequential Atomic Absorption Spectrophotometer, model 220FS and a High
performance liquid chromatograph (HPLC) (Waters 2690 Separations Module, Waters
2487 Dual Wavelength Detector, and a Waters 432 Conductivity Detector). The Soil
Chemistry Laboratory is primarily a teaching facility and, therefore, students are
given priority in use of this facility. Users are trained to use the instruments and
associated software and are expected to prepare, process, run, and analyze their
own samples. Users provide their own standards and QA/QC samples. Users must
also provide their own HPLC columns and mobile phases. For additional -
information and fees for use of instrumentation, contact Dean Rhue at Bill Reve loads a sample into the HPLC
email@example.com. to test for organic acids.
Environmental Hydrology Laboratory
The Environmental Hydrology Laboratory provides specialized laboratory
equipment including a Perkin Elmer gas chromatograph, Dionex accelerated
7 solvent extractor, and an Ocean Optics fiber optic spectrophotometer.
Specialized field equipment includes pressure transducers, autosamplers,
and a Sontek acoustic doppler velocimeter. Services available include
equipment usage, field hydrology assistance, and modeling of contaminant
transport in soils and sediments. For additional information, visit http//

SStable Isotope Mass Spectrometry Laboratory
The Stable Isotope Mass Spectrometry Laboratory (SIMSL)
located in the Soil and Water Science Department.
utilizes a Thermo Finnigan MAT Delta Plus XL mass
spectrometer designed to cover a mass range up to 70
amu to determine the stable isotope ratios of certain
gaseous elements. Since most elements of biological
interest including C. H. O. N. and S have t' ,o or more
stable isotopes '. which fall ..'ithin this range the Delta Plus
XL is '. ell suited for determining the stable isotope ratio
for these elements. The stable isotope ratios of C t N
are routinely determined by Elemental Analyzer Mass
Spectrometry in this facility from plant and soil samples
submitted for analysis. Results are reported as Atom
Atom excess, or Delta o/oo units. Three peripherals
(elemental analyzer, gas chromatograph. and gas bench
are presently dedicated to the mass spectrometer for the
purpose of converting the sample from a solid or liquid
state to a gaseous state prior to introduction into the
mass spectrometer. The SIMSL is under the supervision
of the Soil and Water Science Department: cooperating
departments are the departments of Geological Sciences
and Botany. For additional information on using this
facility, contact Don Graetz at dagifas.ufl.edu.

International Honor Society, and Alpha Zeta. Outside of work, Amy enjoys swimming,
walking, kayaking, and crocheting. Amy can be reached at firstname.lastname@example.org.
Maria Lucia Silveira joined our department as an Assistant Professor at the Range Cattle
REC, Ona, Florida. Maria, a soil scientist, earned her Ph.D. in Soil Chemistry at University
of Sao Paulo, Brazil and University of California, Riverside. Her research program will focus
on soil fertility and environmental nutrient management practices for sustainable forage
production. Research objectives will address critical nutrient and water quality issues
related to beef cattle production in South Florida. She will also work closely with IFAS
extension faculty to promote BMPs for beef and dairy operations. Maria can be reached at
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.
