Week 3 at the Johnson Lab

This week involved analyzing the data from the UMD farm from the previous week. Vials of surface water in the rice tanks and ‘peeper’ water that was soaked in the plants’ roots were all measured. Weight, pH, and changes in color were all recorded. This was good experience for me to learn laboratory skills in sampling and recording.

At the farm, our team measured plant count in the many wild rice tanks. These are controlled for sulfate by measured sulfate being pumped into the surface water of tanks. Bacteria that typically coexist with wild rice also live in the tanks; they fix the sulfate into sulfide which permeates into the water and is lethal to wild rice.
