Description
Lab activity for ESS topic 5.1
Students are introduced to 3 different methods to classify soils and determine their moisture and organic (carbon) content.
Soil classification uses the gravimetric method of placing soil samples in glass gas flasks or graduated cylinders with water, shaking it well and letting the particles fall out of suspension and determine boundaries between sand, silt and clay. These then are plotted on tri-linear soil classification diagrams.
Soil and organic (carbon) content are determined similarly in that the percent difference between wet - dry and with - without carbon can be determined.
Document contains a description of these 3 methods and includes tri-linear soil classification diagram.
