Ch.2.

  • Soil:

    • Where the spheres coexist & interact (having interfaces of different spheres)

    • Subject of many study fields, including environmental sciences

    • Different definitions by different study fields

    •  In this course, we simply define it as “the unconsolidated material on the Earth’s surface”


  • Importance of soil

    • Most agricultural production (producing foods!) relies on it

    • Home of many life forms, consequently, essential part of the balance among the ecosystems on Earth

    • Big buffer against the environmental impacts (natural attenuation)

    • So many (our) activities would not be possible to occur without soil

    • Others

  • Classification of soil http://www.threer.co.uk/services_remediation_natatten.php

    • Genetic classification: zonal, intrazonal, azonal soils

    • Engineering classification: based on the constituent’s grain size and their composition

    • Classification with taxonomy

      • Order > Suborder > Great Group > Subgroup > Family > Series
