|How Chemicals Move Through Soil|
Ideal for viewers concerned with water quality and other groundwater
issues. This video looks closely at how chemicals move through various
soil types and conditions, especially chemicals carried by water. Concepts
presented include chemical transport (diffusion, convection and hydrodynamic
dispersion) ... Chemical interactions (adsorption, absorption, desorption,
cation exchange) ... and chemical transformations (hydrolysis, photolysis,
oxidation and reduction) as they occur in soil. Computer models actively
demonstrate comparisons of different chemicals as they move through soil.
Excellent for students and people working with agriculture, golf courses,
parks, landscaping, athletic fields, wetlands or landfills.
