Student Services and Researcher Services Librarian
by Ruth Gustafson – January 7, 2021
This guide is to help you find information and resources related to soil science.
In a hurry? Your fastest option for assistance is Ask A Librarian 24/7 chat. This service is staffed collaboratively by libraries nationwide, so the librarian who helps you may work outside of UC Davis.
To access resources from off-campus, make sure you are connected to the library VPN.
Includes SoilWeb Apps.
