Industry:Earth science
Entisols that form in recent loamy or clayey alluvial deposits, are usually stratified, and have an organic carbon content that decreases irregularly with depth. Fluvents are not saturated with water for periods long enough to limit their use for most crops.
Industry:Earth science
An organism able to derive carbon and energy for growth and cell synthesis by utilizing organic compounds.
Industry:Earth science
Any interruption in sedimentation, whatever its cause or length, usually a manifestation of nondeposition and accompanying erosion.
