Hello all,



Join us TODAY 4/29/21 for our final session of the Enviro-lunch seminar from 1:30-2:30 pm PST via ZOOM featuring Yocelyn Villa!



We’ve truly enjoyed welcoming you all to the wondering speakers this semester and look forward to our Fall 2021 session which – GASP – could be in person (?!?!)! Stay tuned for that, and for today, we’re excited close out this academic year with one of UC Merced’s very own, Yocelyn Villa! Details below!!


Title: Soil carbon response to long-term biosolids application

Abstract: Biosolids are the nutrient-rich organic residues resulting from anaerobic digestion of wastewater. New legislation in California aims to reduce organic wastes such as food and biosolids into landfills by the year 2025 by 75% compared to the 2014 level (SB. 1383). One potential beneficial reuse of biosolids is as a soil amendment that supplies a large source of carbon (C) and nutrients to managed lands. California has a total land area is approximately 50% rangelands, most of which is primarily used for grazing livestock. Rangelands store most of their C belowground where it can stay for long periods of time. Hence, using these organic wastes in grazing lands has been proposed as a climate beneficial practice and a method to improve soil health. However, the extent to which this source of organic material effects soil C stabilization has not been fully tested. While clay content is often used to infer to soil carbon stabilization potential, it is a poor correlative. Emerging research points to other soil physicochemical factors that better relate to soil C and provide mechanisms for C stability. Our goal is to assess how long-term biosolids application influences C storage and stability in three agroecosystems in California.

Bio: Yocelyn is a fifth year Ph.D. student working in Dr. Rebecca Ryals lab at UC Merced. She received her Bachelor’s of Science from UC Riverside in Environmental Sciences. Her dissertation focuses on how the use of organic amendments influences soil quality and health and climate change mitigation strategies.
