-[Ella McKinney] I think if you have an interest
00:00:08
in environmental issues, i think that soils are really the place to start.
00:00:12
Everything comes back to soil
00:00:15
and I think that if you can understand those processes you can help
00:00:20
really make a difference.
00:00:22
-[Steve Maestas] One thing that I really like about my major is that we're protecting not only
00:00:26
the environment, but public health.
00:00:28
Right now I work for the environmental department at NASA
00:00:31
and what we're in charge is the compliance, the regulatory side
00:00:36
of the work that happens at NASA.
00:00:39
-[Joel Brown] In USDA, we spend billions of dollars every year on conservation programs,
00:00:45
and those conservation programs are all directed
00:00:49
at improving the quality of life
00:00:52
for citizens in general, and improving the sustainability of agriculture.
00:00:58
So, we really have to have a working knowledge of soils
00:01:02
that will allow us to understand where to put certain conservation practices,
00:01:07
and you know in any particular landscape which
00:01:11
soils we want to treat first, or which soils are the most critical.
00:01:15
-[Steve] One of the amazing things about soils is
00:01:19
they have properties to remove contaminants from water.
00:01:22
What I do here on the University, is we take soils that are
00:01:26
native here to New Mexico and we try to calculate how much
00:01:30
these contaminants they can absorb.
00:01:33
So, what I will do is take known weight of
00:01:37
these soil particles, mix them
00:01:41
with an arsenic solution to see how much arsenic
00:01:45
that the sand can remove.
00:01:47
After the experiment is over and the calculations are made, we also tried to
00:01:52
desorb the arsenic from
00:01:55
the sand to see if we can reuse that sand as another filter media.
00:02:00
-[Ella] As a student, I got to participate in a soil survey at Glacier National Park in Montana.
00:02:06
And, I got to see more of that national park than most people get to see in their entire life.
00:02:12
We got to camp out pretty much for 12 weeks.
00:02:14
Even just as a science student, it was really cool looking at the processes that form soil,
00:02:21
and digging our holes, and characterizing it, and understanding more about the processes
00:02:25
that form the park and management in the area.
00:02:29
It's neat in the lab when I can take soil
00:02:35
and culture the microbes and look at them under the scope and get to see
00:02:40
just this world that other people don't get to see.
00:02:43
I get to see the crystals forming in the soil, the casting carbonate crystals.
00:02:47
And it's just kind of cool getting to see the processes that make soil do what it does.
00:02:54
-[April Ulery] Soil science is often thought of being just agronomy or farming, but it's more than that.
00:03:03
It's about the environment.
00:03:07
It's about water storage and purification.
00:03:11
It's about climate control.
00:03:14
It's about carbon sequestration.
00:03:17
Soil is the key to
00:03:21
so many different environmental issues
00:03:24
that it's actually the critical zone where
00:03:28
a lot of the science has come together and need to be addressed.
00:03:34
-[Ella] I really feel that when it comes to Science and Education,
00:03:38
I don't feel like there's a ceiling on that.
00:03:41
I think there's always something to be
00:03:42
explored, something to be looked at, something to be taught.
00:03:46
And what I really like about soils is that
00:03:49
it has something--it has some part of every type of science,
00:03:54
and there's literally nothing you can do with the soils degree.
