The Soil and Water
Science Depart-
ment (SWSD)
along with other
UF-IFAS
Departments and
centers is going
through tough
times as a result of severe budget cuts during the
fiscal year 2001-02 with more expected during
the next fiscal year. This requires all of us to
conserve our resources and find alternate ways
to strengthen our programs. In spite of the
current statewide budget shortfall, the need to
address soil and water quality issues is at an all-
time high. This places us in a responsible
situation to meet the statewide needs and
demands. The SWSD faculty continue to explore
new opportunities by expanding their programs
and developing scientific knowledge that will help
to address statewide needs to protect soil and
water quality. To address these critical needs,
we have been actively developing strategies to
enhance our teaching, research, and
extension/outreach activities. Here are a few
recent examples:

* Our undergraduate programs are
now modified to address the needs of our
diverse students. We now offer three tracks:
Environmental Soil Science,
Environmental Water Science, and
Environmental Management and Policy.
* Our graduate student enrollment is strong
and interest in our programs is increasing.
We have redefined our graduate tracks: Soil
Science, Environmental Science and Water
Science.
* We have initiated a new distance
education graduate program. We plan to offer
an M.S. degree with emphasis in
Environmental Science at select UF-IFAS
research and education centers.
* We have initiated several new
undergraduate and graduate courses to meet
current needs in our teaching program.
* Our grant activity is at an all-time high.
We have a number of recently funded projects
from state and federal agencies.


* Our first Soil and Water Institute
outreach activity entitled "Principles of
Arsenic Behavior in Florida Soils" is
scheduled for March 4-5, 2002,
Gainesville, Florida.
* Lena Ma's fern research program
won the Discovery 2001 Award from
Discovery Networks Europe and Royal
Geographical Society.
* P.S.C. Rao, emeritus graduate
research professor was recognized as
highly-cited researcher by the Institute for
Scientific Information.
* Mary Collins, professor in
environmental pedology, was appointed as
Division 1 Secretary of the International
Union of Soil Science.

In this newsletter we feature one of our
thrust areas: Soil-Landscape Analysis.
The goals of this thrust area are to (1)
improve the understanding of soils as
natural bodies within landscape, and (2)
develop techniques for landscape-scale
modeling and risk assessment that can be
applied to both rural and urban settings.
This program also involves the
maintenance of expertise in geographic
applications (e.g., GIS, geostatistics, etc.),
and a departmental commitment to multi-
disciplinary research at environmentally
relevant scales. Our new faculty member
Sabine Grunwald, assistant professor, has
established a GIS laboratory to coordinate
teaching and research activities in this
thrust area.

We will be going through some tough
times in the next few years, but in spite of
budget limitations, we are committed to
maintain excellence in our programs by
redirecting and conserving our resources.
To meet these challenges, we need the
support and help of our emeritus faculty,
alumni, friends, and our clientele. Please
send me your ideas and suggestions.

3D Reconstruction and Visualization of Soil-Landscapes


Commonly, crisp 2D soil polygon maps
and associated attribute tables utilizing
geographic information systems (GIS) are
used to describe the spatial distribution of
soils (e.g. SSURGO and STATSGO).
Other soil-landscape representations use
a 2/2-D design, where soil or land use data
are draped over a digital elevation model
(DEM) to produce a 3D view. Since this
technique describes patterns on 2D
landscape surfaces rather than the spatial
distribution of subsurface attributes (e.g.,
soil texture, soil horizons) it fails to
address three-dimensional soil-landscape
reality.

In the recently formed research program
'GIS and Land Resources' at the Soil and
Water Science Department led by
Assistant Professor Sabine Grunwald we
integrate soil observations with emerging
technologies to create holistic, object-
oriented, multi-dimensional soil
landscape models. We employ
geostatistics to create continuous 3D

soil-landscape models and scientific
visualization to render and display
models at a variety of different scales.
These models enable us to
comprehend soil-landscapes intuitively
and gain insight into complex
environmental systems. Spatial
pattern analysis facilitates to quantify
and analyze soil and landscape
patterns.

In the thrust area 'soil-landscape
analysis' we address such questions
as: Are soil patterns related to
geographic position (x, y) and depth
(z)? What is the spatial orientation and
arrangement of soil patterns in 3D
geographic space? Do patterns
change across scales? Are patterns
related to each other or other factors
(e.g. topography)? Which are the
underlying processes forming these
patterns? For additional information
contact S. Grunwald
(sgrunwald@mail.ifas.ufl.edu).


Ground-Penetrating Radar (GPR)
has proven to be an efficient, non-
invasive, timesaving tool used to
identify subsurface features. Within
the state of Florida, GPR has been
used to accurately identify sinkholes,
solution pipes, Ocala limestone, and
Hawthorn Clay. In addition, spodic
and argillic horizons are also easily
identified with GPR. Recently,
georeferenced soil and geologic
information, an example of
Geographic Information Systems
(GIS) data, has been in high
demand, and proved incredibly
useful. Michael Tischler, Mary
Collins, Sabine Grunwald, and
Michael Binford are producing a 3-
dimensional soil model that can be
combined with previous
GIS data to allow for more powerful
analysis of subsurface activity. The soil
information is being gathered using GPR
at the IFAS Plant Science Research and
Education Unit at Pine Acres in Marion
County, FL. The Hawthorn formation is
very evident at this location, and is
providing a dynamic soil model. An
accurate 3-D model will be created using
current interpolation and geostatistical
techniques. This model is also being
geographically referenced using a
Global Positioning System (GPS)

GPR, GPS, and GIS technologies will be
used in combination to allow analysis of a
site without penetrating the soil surface.
Furthermore, making such a model
compatible with previous GIS data allows
for comparative analysis regarding a
number of issues. By making


use of the 3-D model, several
disciplines including Agronomy,
Agricultural Engineering, Animal
Science, and Horticulture and
Education will benefit by having the
opportunity to make wiser
experimental design decisions. For

International Activities
The Soil and Water Science Department hosted five trainees
from the Indian Council of Forestry Research and Education
for two weeks in October 2001. The scientists had the
opportunity to familiarize themselves with the various thrust
areas within the department. Their training was primarily on
the environmental impacts of nutrient additions to agricultural
soils, and included soil analytical procedures and
instrumental analyses.


Upcoming Conference
The Soil & Water Science Department will be hosting the
"2002 Southern Soil Fertility Conference" to be held in
Memphis, Tennessee in October. Rao Mylavarapu has been
