<p class="MsoNormal">Soil is a thin layer of the Earth's surface that
lies between the world of rock, air, water, and living organisms. It
serves as an essential medium that allows active cycles and flows of
materials and energy that support terrestrial life.
The movement of energy and mass in soil occurs at different scales,
where a complex array of non-linear processes interacts. While we often
evaluate the impacts of these processes at larger scales, the regulation
of transport behaviors of soil constituents
often happens at local or smaller-scales. Therefore, in this
presentation, I will present results from two studies under distinct
soil moisture conditions (i.e., saturated versus unsaturated) to
demonstrate the impacts of small-scale transport processes on
soil functions. One is focusing on nano-sized soil colloid mobilization
and its role in carbon cycles, and the other is on rhizosphere water
and nutrient management and sustainable agriculture. The mechanistic
understanding of small-scale transport processes
will be implemented into predictions of larger-scale cumulative effects
through integration of experimental and modeling approaches. The
presentation will welcome and promote discussions from different
scientific disciplines and perspectives, focusing on how
to connect environmental processes at different scales to ecosystem
service management.</p>

<p class="MsoNormal">Jing Yan is an environmental soil physicist by
training. He is broadly interested in developing basic and applied
research of soil physics to promote food, water security and healthy
ecosystem services. He gained his Ph.D. degree in Plant
and Soil Sciences from University of Delaware. After graduation he
joined University of California, Merced, for his postdoctoral training.
His postdoctoral research is under the direction of Dr. Teamrat
Ghezzehei, mainly focusing on rhizosphere nutrient and
water dynamics. In addition to performing research, at the University
of California, Merced, he actively promotes an interdisciplinary
research community through serving as organizer of Enviro-Lunch
seminar-series and postdoctoral ambassador to unite different
scientific disciplines and graduate programs.</p>
