Hello all,



This week we invite Dr. Si Gao, a postdoctoral scholar at Oregon State
University. She studies biochar and its effects on soil nutrient dynamics.
Please join us this Thursday (2/11/2021, 1:30-2:30 pm) for her talk.

*Title: *

Locally produced wood biochar in the US Northwest: influence on soil
nitrogen and phosphorus dynamics



*Abstract: *

Producing wood biochar from timber harvest residues and applying it to
nearby soils represents a means of addressing fuel management in the
western US while providing an innovative approach to potentially improve
soil fertility and plant productivity.  Using a series of lab and field
experiments established in Washington and Montana, my research is to
understand the influence of locally produced wood biochar on soil nitrogen
(N) and phosphorus (P) dynamics at agricultural, rangeland, and forest
ecosystems of the Northwestern US.  Several research topics that will be
covered in my talk include:

1)     Responses of soil N and P pools and fluxes, microbial communities,
and crop productivity to short-term wood biochar addition at small-scale
organic farms of the Pacific Northwest

2)     Use of wood biochar with or without manure on soils of a semi-arid
semi-natural rangeland ecosystem in western Montana

3)     Rotational cattle grazing and wood biochar interact to influence
rangeland soil and grass nutrient dynamics

4)     Influence of biochar addition on forest soils exposed to fire
retardant chemicals at the US Inland Northwest

Dr. Gao is a postdoctoral scholar at Oregon State University. She received
a PhD in Forest & Conservation Sciences from the University of Montana. She
is a soil scientist and ecosystem ecologist, broadly interested in
understanding the functions of pyrogenic carbon in soil carbon and nutrient
cycling in natural and managed ecosystems.



Best regards,
