Updates from the Parikh Lab
March 31, 2020
This is a challenging time for our planet, our nation, and the UC Davis community. UC Davis continues to follow the guidelines to shelter in place and practice physical distancing due to COVID-19. The campus remains closed except to essential personnel. All classes have shifted to online teaching and only essential research is continuing. For those looking for official information, UCD has set up web pages related to COVID-19 for the Campus Community and with the Latest Campus Updates. For information regarding COVID-19, the CDC remains one of the best sources. Aside from the physical illness concerns, coping with the current situation can be difficult for all of us. If you are concerned about others, or yourself, please refer to resources from the CDC to reduce stress and anxiety. For those on campus, consider the Student Health and Counselling Services or the Academic and Staff Assistance Program.

In response to the COVID-19 pandemic, UC Davis has limited lab activity for only essential research. While our research is very important, we are winding down our activities for the time being. We will continue to evaluate the situation and conduct any essential research and open the lab back up for full use when it is deemed safe to do so.

We conducted a group project with many members of the lab contributing throughout the process. In this research, we were seeing if we could replace peat moss in a potting mix with biochar for a more sustainable growth media. It turned out that we could do a full replacement and have no adverse growth effects, and that a partial replacement (mostly biochar) could be beneficial for marigold growth. Our efforts were rewarded with a paper accepted to Industrial Crops and Products.
