Intended Learning Outcome Students are able to analyze processes, functions and potential uses of soils by

  • characterizing chemical, physical, and biological soil properties and processes,
  • comparing different soil management practices, and
  • identifying causes of soil degradation and the potential for soil restoration measures

in order to  develop sustainable soil and land management practices in tropical and subtropical environments.

Content Block I: Soil development and properties

  • Soil as a system
  • Rocks, minerals and soils
  • Soil development
  • Clay minerals
  • Organic substance in soils
  • The soil profile
  • Soil chemical properties and processes
  • Soil physical properties and processes
  • Soil biological properties and processes

Block II: Soil classification and soils of the tropics and subtropics

  • Soil mapping
  • Soil classification systems
  • Major soils orders according to FAO/WRB and US Soil Taxonomy
  • Major soils of the tropics and subtropics, their distribution, characteristics, land use potential, and vulnerability

Block III: Soil management

  • Principles of soil management
  • Managing soils of humid and semi-humid regions
  • Managing soils of arid and semi-arid regions
  • Managing soils of the Mediterranean regions

Block IV: Soil degradation and restoration

  • Soil degradation as a global environmental problem
  • Soil erosion – social and ecological implications
  • Soil compaction: causes, effects, prevention
  • Salinization in arid lands and in coastal areas
  • Desertification in semi-arid regions
  • Soil restoration practices in degraded lands
Teaching Method Lectures, field trips, exercises and case studies
