pedogenic prosess Flashcards
1
Q
what is pedology
A
the study of the formation, characteristics, and distributions of soil
2
Q
what is pedogenesis
A
the process of soil formation
3
Q
what are the four basic pedogenic processes
A
- transformation
- translocation
- additions
- losses
4
Q
what is transformation
A
occurs when soil constituents are chemically or physically modified or destroyed
ex weathering of primary minerals, decomposition of plant inputs to form soil organic matter, changing the size and aggregation of mineral particles
5
Q
what is translocation
A
inputs of materials to the soil profile from outside sources
ex. inputs of organic matter, dust particles depositing, manures and fertilizers
6
Q
what is losses
A
losses of materials from the soil profile
ex. leaching of soil, erosion of surface materials, animal grazing
