Soil Unit: Intro
SOIL IS:
- a medium of crop production
- a snapshot of geologic, climatic, biological and human history.
- a waste decomposer
- a source material for construction
- a filter of water and wastes
- an essential natural resource
- a producer and absorber of gasses
- a home to organisms, animals and others(us?)
- physically support plants
- provide spaces underground for water and air
- provide essential nutrients growth
- contain mineral particles(texture)
- provide a home for a myriad of organisms(which help bind soil together and release nutrient)
Some factors of soil creation are:
- Parent material. Solid mineral form, rock etc.
- Weathering/Climate. Physical and chemical, plays an essential role of releasing mineral elements from the parent material(rock)
- Organisms. Break down organic matter into mineral elements. Also feed on mineral elements of parent material hastening the weathering process.
- Topography. Generates, directs and catches the minerals weathered from the parent material.
- Time. Soil formation takes time for all the processes to express themselves.
