Standard Operating Procedures (2.2): Soil Grain Size and Organic Content

The objective of this Standard Operating Procedure (SOP) is to describe the equipment and protocols for analyzing soil grain size and the percentage of organic matter in the sample. With some modifications, organic content analyses can be modified to assess “blue carbon” stored in soils, which is critical for understanding the role of wetlands in the context of climate change (see Howard et al. 2014).
