A Soil and Water Science Department Publication

Volume 3 Number 1 Institute of Foodand Agricultural Sciences Spring 2003


The University of
Florida and IFAS
are celebrating UF's
year in 2003. This
highlights faculty
excellence with the theme, "honoring the
past and shaping the future." In almost 100
years, Soil and Water Science Department
(SWSD) faculty, staff and students have
made significant contributions to improving
the quality and productivity of Florida's
agriculture and natural resources. Soil and
water science related research in Florida
was first published in 1888 by the newly
established Experiment Station of the State
Agricultural College of Lake City, Florida.
Early soil survey maps developed in 1904
included soils of Alachua, Levi, and Marion
counties and showed Alachua Lake (Paynes
Prairie) filled with water. In 1907, the
Experiment Station was moved from Lake
City to Gainesville. The present Newell Hall,
then called the Experiment Station, was built
in 1908. Early research included the use of
lysimeters to study nutrient leaching in sandy
soils. Water quality has been the focus of
the SWSD during the past four decades and
during this period our faculty have made
major contributions at state, national, and
international levels and brought recognition
to the department and to the UF. The
department has been blessed with excellent
faculty. In the history of the department, 24
faculty members (13 retired) were elected as
fellows of the Soil Science Society of
America and the American Society of
Agronomy, the highest recognition given to a
scientist at the national level.

Today, the soil and water science programs
are more complex and require expertise from
various disciplines. To develop
interdisciplinary connections, it is critical for
us to maintain disciplinary strength,

which the SWSD has done effectively over
the years. The interdisciplinary nature of
SWSD programs provides students and
faculty an opportunity to conduct basic and
applied research at multiple scales, from
molecular to landscape, to solve
environmental problems and protect and
manage land and water resources. We
conduct research in a wide range of
ecosystems, including agricultural lands,
forested lands, range lands, urban lands,
and wetlands and aquatic systems. In this
newsletter, we showcase a few examples
of interdisciplinary projects initiated by our
faculty in collaboration with faculty from
other disciplines.

Our faculty recognizes the importance of
interdisciplinary approaches in addressing
complex soil, water, environmental issues. At
present all our grant projects involve one or
more scientists from other disciplines,
including several UF departments and
scientists from other universities in the U.S
and other countries, and state and federal

These are challenging times, with severe
budget reductions, limited resources, and
complex soil, water, and environmental
issues, forcing us to think "outside the box"
and explore new opportunities. We are
making concerted effort to reach out by
forming teams with other disciplines. To be
successful in this effort, core disciplinary
strength must be maintained. We strongly
believe that programmatic team-building is
important for success of our department,
IFAS and UF, and we are doing our share to
accomplish this goal. To our friends and
alumni, we thank you for your support of our

Phytoremediation Research on Arsenic Hyper-accumulation by Chinese Brake Fern

The discovery of the first known
arsenic hyperaccumulating plant in
the world, P. vittata, commonly known
as Chinese brake fern, marked the
beginning of our efforts to understand
why this peculiar plant has the
extraordinary capability to accumulate
huge amounts of arsenic and yet grow
well. The discovery was published in
Nature in 2001 and received
unprecedented publicity worldwide.
This all started with Kenneth
Komar who joined the Bio-
geochemistry of Trace Metals
Program in 1998 as a M.S. student
under the supervision of Lena Q. Ma.

One of the objectives of his research was
to screen arsenic accumulating plants
from an arsenic contaminated site. The
arsenic hyperaccumulating plant was one
of the more than a dozen plant species
he collected from the site.

The long-term goal of our research
program is to understand the
mechanisms of arsenic hyper-
accumulation by this plant, more
specifically the mechanisms of arsenic
uptake, translocation, distribution and
detoxification by Chinese brake fern.
Significance in science and application
of this research has resulted in interest
by scientists from many disciplines.
The first joint effort was funded by
the National Science Foundation to
determine the feasibility of using
Chinese brake to phytoremediate arsenic
contaminated soils and wastes.
Scientists involved in this research
include Dr. Alex Green from Mechanical
Engineering Department, Dr. Greg Erdos
from Interdisciplinary Center for
Biotechnology Research, and Dr. Yong
Cai from Chemistry Department of the

Florida International University. To better
understand the mechanisms of arsenic
hyperaccumulation and enhance its
potential for phytoremediation, a

Travis Shaddox, a PhD student,
conducting research on turfgrass water
use efficiency

Through interdisciplinary efforts over the years, a strong research and education program has
been developed within SWSD in the area of turfgrass fertility management and assessment
as it relates to environmental impact and water quality. These efforts have been carried out
by six faculty and five graduate students, within and outside of the department, and three
support staff under the leadership of J.B. Sartain. Currently there are four Ph.D. and one M.S.
graduate student working on various research projects related to turfgrass nutrition and the
improvement of fertility management practices. This program is currently supported by grants
from the Florida Turfgrass Association (FTGA), Florida Department of Agriculture and
Consumer Services (FDACS), Florida Department of Environmental Protection (FDEP),
United States Golf Course Association (USGA), The American Association of Plant Food
Control Officials (AAPFCO) and eleven industry related organizations.

The objectives of this program are to determine: 1) the environmental impact of various turfgrass fertility management programs
during grow-in and post-construction management, 2) correlate nutrient application rate, extractable soil nutrient test levels and
turfgrass tissue nutrient levels with turfgrass growth and quality, 3) nutritional requirements of cool and warm season turfgrasses that
will promote a high quality transition from cool to warm season turf, 4) the influence of N and P application and various growth media
mixtures on contamination of ground water, and 5) various materials for use in turfgrass culture as soil amendments or as
topdressings. Turfgrass is a major commodity in Florida with over 4 million acres of home lawns and 200,000 acres of turfgrass on
over 1400 golf courses and an economic impact in excess of $ 8 billion. Many feel that turfgrass is detrimental to the environment but
through the research efforts of the Turfgrass Nutrient Management Program within the SWSD in collaboration with faculty in
Environmental Horticulture Department and Ft. Lauderdale REC, we have discovered that turfgrass can be grown-in on a fairway with
less than 4% of the N leached and maintained in a post-construction environment without any N loss. It has also been discovered that
turfgrass in the landscape uses less than half the water and leaches far fewer nutrients than trees and shrubs. We will continue our
efforts to improve the fertility management practices of turfgrass in Florida in an attempt to dispel some of the unjust claims being
directed towards turfgrass and its management. For additional information, contact Jerry Sartain at: jbs@ifas.ufl.edu.

The UF/IFAS Role in the
USDA-CSREES National Water Quality Program

The USDA-CSREES nation water quality program, which is funded by the USDA's National Program Office for Water Quality, is a member of
the larger CSREES (Cooperative State Research, Education, and Extension Service) Integrated Research, Education, and Extension
Competitive Grants Program. It is often referred to as a "406" program because of its legislative roots in Section 406 of the Agricultural
Research, Extension, and Education Reform Act of 1998 (AREERA). Cooperative Extension personnel from across the nation are involved,
including: scientists learning new insights about agriculture the natural environment, instructors teaching within land-grant universities and
community workshops, extension educators working with local community decision-makers, youth, the underserved, and the general public.
All are effectively working to improve the quality of our nation's water resources. The goal of the program is to apply knowledge to protect or
improve the quality of water resources throughout the United States and its territories, particularly in agriculturally managed watersheds at the
national, regional, state and local levels. The CSREES National Water Quality Program consists of nine Regional Programs (based on the ten
EPA regions), along with national facilitation, extension education, and integrated research, education, and extension projects. Florida is part
of the Southern Regional Water Quality Program, which consists of 13 states from New Mexico to North Carolina. Our website address is

The SWSD faculty involved in water quality extension programs include: Tom Obreza: Nutrient/water management and extension water quality
coordinator; Rao Mylavarapu: Nutrient management, soil testing, and fertilizer recommendations; Mark Clark: Wetland resources and
watershed management; Jerry Sartain: Nutrient management for turfgrass; Yuncong Li: Fertilizer and irrigation management for vegetables
and tropical fruits; Craig Stanley: Water management for vegetables and ornamentals; Chris Wilson: Aquatic ecological risk identification and
mitigation. The SWSD 406 funds will support travel and registration costs for eight county agents and seven extension specialists to attend
the Southern Region Extension Water Quality Conference in Ruidoso, New Mexico in October 2003. Three agents and three specialists will
present examples of their extension programs at the conference. For additional information contact: Thomas Obreza, Extension Water
Quality Coordinator, at: taob@ifas.ufl.edu


Several of our faculty and staff retired during the current fiscal year. We wish them
all the best and enjoyable retirement years.

David Calvert started his career at the Indian River REC, in 1962. During his tenure
he also served as center director for seventeen years. His research program
addressed the applied nutrient management issues facing Florida citrus grown on
Flatwood soils, as related to environmentally sound management of this billion dollar
commodity in the State of Florida. He is also actively sought by the citrus industry
and state agencies to aid in developing best management practices for this

Bob Mansell joined UF faculty in 1968. His responsibilities included research and
teaching. His research focused on coupled water-heat-chemical transport in plastic-
covered soil beds during vegetable production; transport of reactive chemicals
during variably-saturated water flow in subsurface porous media; density-coupled
water flow and contaminant transport; and wetland hydrology and water quality.

Hugh Popenoe joined UF in 1951. In addition to his research in tropical agriculture,
Dr. Popenoe was appointed for various administrative positions, including Director of
the Center for Tropical Agriculture in 1965 and Director of International Programs in
Agriculture in 1966. In addition he initiated and was Director of the Florida Sea Grant
College from 1971 to 1978. He has traveled and worked in most of the tropical
countries of Asia, Africa and Latin America.

George Snyder joined UF at the Everglades REC in 1967. He studied the
management of soil, water, fertilizers and pesticides to optimize crop production and
minimize losses of nutrients and pesticides. His research has focused on the
organic and sand soils of south Florida and has involved vegetables, pasture,
sugarcane, rice and turfgrass. Dr. Snyder has taught soil science courses for fifteen
years as part of the undergraduate degree program at the Fort Lauderdale REC.

Mary McLeod joined UF as USPS staff in 1965. She spent her career in the Forest
Soils Laboratory and was promoted numerous times as the program grew.
