Environmental Soil Chemistry
Study of soil chemical processes such as weathering, adsorption, precipitation, complex formation, and ion exchange; causes of soil acidity, alkalinity, and salinity; reactions between soil and fertilizers, bio-wastes, pesticides, and heavy metals.
Skills and knowledge to be acquired:
Skills: Know how to determine chemical analysis of soils, fertilizers, and biowastes. Knowledge: Know what to expect from a soil using its chemical and mineralogical properties or when inputs, such as fertilizers or heavy metals, are needed.
Computer skills to be acquired:
Know how to estimate ion concentrations in the soil solution, to predict the thickness of a diffuse double layer.
