Hello all,



Hope you are doing well.  The Envio-Lunch seminar series continues this
semester. As always, we lined up great speakers from different backgrounds,
so please check the schedule below and join us on Thursday 12-1 pm via
zoom. Our first seminar will be on Sep 10th and Shane Franklin from U of
Delaware will present about soil physics.

*Title: *

Preferential flow plays an unknown role in the carbon cycle



*Abstract:*

Preferential flow refers to the uneven infiltration of water through soil,
where a portion of the soil matrix is bypassed. Primary interest in
preferential flow has largely dealt with contaminant transport and
modelling approaches, but interestingly,these moisture highways play a role
in biogeochemical cycling as well.Preferential flow paths have been found
to contain higher concentrations of carbon, nitrogen, and microbial
biomass, but the implications of this have not been fully explored.
Additionally, preferential flow paths show temporal stability, meaning they
are reactivated over time. We will dive into the biogeochemical properties
of preferential flow paths and discuss their impact on carbon cycling as
well as their potential to be used to upscale biogeochemical heterogeneity
in soil.
