Soil Sampling 2018
The Andrews Forest Long-Term Ecological Research program includes a long-term soil study. Researchers dig soil pits to measure, weigh, sample, and describe the soil, across multiple locations in the forest and over many years. This photo gallery is a snapshot of the soil sampling field work in Watershed 2 in the Andrews Forest, in summer 2018.
