Getting the Dirt on Soils
Undergraduate Studies in Environmental Soil Science Clay mineralogist Sridhar
Komarneni was working on his masters
degree in agricultural chemistry when the first man landed on the moon. They
collected lunar soils and brought them back to earth to analyze, he
says. What they found was a very different mineralogy. The moon
doesnt have the same weathering processes as earththeres
no rain, no wind. It doesnt have the same clays. Thats when
I knew I wanted to understand the chemistry of soils.
Soil scientist
Daniel Fritton, who grew up on a farm in eastern Colorado, figured hed go back to the farm after graduationuntil he
took his first soils class. I walked on soil every day, he
says, but I never realized what went on in it. We continue to try
to understand it, and we struggle to manage or repair it.
Today, great resources and dedicated faculty like Fritton and
Komarneni make Penn States Environmental Soil Science major one of the best in the country. Every
graduate in the past 10 years has had an opportunity to work as a soil scientist, says
Fritton, who coordinates the program.
Graduates can apply for certification as a soil scientist, soil specialist,
or soil classifier. Typical starting salaries are $25,000 per year, with frequent
promotions to higher-paying positions after six months to two years.
If you want to work outdoors, this is an excellent major, Fritton
says. Field scientists are in the trenches, mapping soils. They interpret
soil maps for specific uses, like construction, agriculture, forestry, and waste
disposal. Since the soil and water are closely linked, they frequently also look
at a soils effect on water quality.
There are so many avenues you can take, adds instructor Kate Butler,
who teaches courses in soil science. If you like lab work, you can study
soil chemistry and reactions, or you can study microbiology and investigate the
billions of diverse and elusive soil organismsmost of which have yet to
be identified. If computers are your passion, there are exciting programs for
mapping and interpreting soil data.
Traditionally, Soil Science focused on fertility for plant growth and crop
yield, and some students specialize in that today, says Fritton. But
were also focusing on how soils maintain a habitable planet.
I knew I wanted to work outside in an environmental field, says Duane
Goodsell, who earned his degree in May 2001. As a kid, environmental problems
were happening all around me. I grew up near Spring Creek, in Lemont. Kepones
from leaky lagoons ended up in the creek, and there was a contaminated spring
a half mile from my house. People living near it complained of the strong smell
and headaches. Today you still cant eat the fish.
After graduation, Goodsell went to work for Meiser and Earl Hydrogeologists,
a State College environmental firm, where he does a little bit of everything.
Theres never a typical day, which is nice, he says. I
dont just sit at a desk. Today, Im going to run a video camera down
a well to look for a coal mine. The people who drilled the well wanted to hit
a mine filled with water. Ill look for indications of fractures, so they
can enlarge them to reach the water.
Goodsell says many people, including his fellow students, dont realize
how many applications soil science has. When I tell people Im a
soil scientist, they immediately think: agriculture. But there are all kinds
of jobs outside of agriculture too, like wetland delineation, where you go
out and locate the boundaries of wetlands for construction projects.
We get called out to do all kinds of things, he says. Fifteen
years ago, the company was hired to help out with a murder investigation, looking
at soils in a pit where a dead body was found.
Jaime Carson, who earned her degree in December 2000, grew
up in Philipsburg, where she saw a lot of red- water streams
from abandoned coal mines. I
went into soil science because Im interested in the environment, she
says. I wanted to make a difference.
Today, she works at the USDA Pasture Systems and Watershed Management Research
Laboratory, where she analyzes soils and water samples for research projects
on phosphorus.
Most of my courses had labs or field trips, which was great for me because
I learn by doing. Because of the small class size, I got a lot of one-on-one
work with instructors. We took a lot of field trips where we practiced describing
soils, based on color chips, texture, and other properties. We made a lot of mud
pieswhere we wet the soil and roll it in our fingers to feel for
the sand, clay, and silt. Judging soils is an art, not just a science.
The faculty are great, she adds. Theyre really willing
to helptheyll take you out on an extra field trip if you need it.
They go above and beyond.
Many students also get extra hands-on experience through part-time
positions at soil research and service labs at University Park,
including the Natural
Resource Conservation Services Map Compilation Center, the USDA Pasture
Systems and Watershed Management Research Laboratory, Penn States Agricultural
Analytical Services Laboratory, or individual faculty labs.
