7.0 Characterization and Selection of Soils

7.1 Soil Characterization Tests

7.1.1 Physico-Chemical Characteristics 178 impact the performance of an analytical method or system. Three main soil properties are 179 expected to have the most impact on an experiment or test: organic carbon content, clay 180 content/soil texture, and soil pH. In addition, moisture content can affect the viability of 181 biothreat agents as well as interactions between biothreat agents and chemical or 182 biochemical constituents in the soil. 183 Soil is a very complex medium and the physico-chemical characteristics of a soil can
