Document Summary

Composed of solid, liquid, and gas, and diverse community of living organisms. Liquid: contain chemicals dissolved from mineral phase or entered through soil surface. Found in spaces between the solid particles. Gas: dominant influence on heat, water, and chemical transport and retention processes. Physical and chemical properties of their surfaces. Size/texture: qualitative classification of how soil looks and feels. Determined by size and type of particles in soil. Mostly in relation to inorganic material (minerals) Different sized particles classified by groups based on particle diameter. Soils given different names based on amount of sand, silt, and clay present. Loam: mix of roughly equal proportions of different particle sizes. Regarded as mixture of secondary minerals or weathering products. Significant influence on many physical and chemical processes in soil. Smaller particles have large and reactive surface area. Cohesive, difficult to detach, but easily carried great distances once detached. Silt: can be well aggregated, but aggregates break down when wetted, easily transported.
