  • soil-forming processes - soils acquiring and maintaining, their characteristics and composition;
  • soils, being open systems - subjected to energy and substance dynamics;
  • geographic location, a major control - of average soil temperature and seasonal dynamics;
  • external features - modifying energy exchange reactions;
  • water exchange processes, like energy - water, instrumental in all biogeochemical reactions within the soil;
  • lateral redistribution of water - among soils on sloping land;
  • leaching, analogous to eluviation - by solution, connoting removal from the entire solum;
  • processes of soil formation - complexes of subprocesses and reactions;
  • horizonation processes - responsible for presence of identifiable horizons in soils;
  • haploidization processes – pedoturbation, process of mixing in the soil


This chapter contains sections titled:

  • Conceptualizing the Environment of Soil Formation

  • Intrasolum Translocations and Transformations

  • Simplified Model of Solum Development

  • Perspective
