What is catena in soil science?
A catena is the sequence of soils from hilltop to valley floor. The soil down a hill slope is rarely uniform. Soil eroded from the top of the slope tends to accumulate near the bottom.
What are the characteristics of a catena?
A catena is thus an open system which has continuous input and output processes. On a steeper slope in the middle of a catena, erosion, such as by runoff, is faster, so facets are typically thinner and drier. Conversely, on a shallower slope at the top or bottom of a catena, soils are thicker and deeper.
Why do soils differ along a soil Catena?
The soils of a catena differ not only in morphology but are considered to differ as a result of erosion, transport and deposition of surficial material as well as leaching, translocation and deposition of chemical and particulate constitutente in the soil.
What are soil forming processes?
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
How does a catena differ from a normal soil?
Catena on the other hand carries with it a process-response connotation. The soils of a catena differ not only in morphology but are considered to differ as a result of erosion, transport and deposition of surficial material as well as leaching, translocation and deposition of chemical and particulate constitutente in the soil.
What kind of research is done in Catena?
Catena publishes papers describing original field and laboratory investigations and reviews on geoecology and landscape evolution with emphasis on interdisciplinary aspects of soil science, hydrology and geomorpholo… M. Khorchani, C. Tague
Is the FA Catena a source of environmental pollution?
FA catena across the world is a source of environmental pollution to the residents of local livelihoods near the coal-based thermal power plants, despite the various agreements and policies related to FA utilization at national and international levels.
Why are the horizons so thick in Catena?
Soils developed in this location are commonly over-thickened as a result of both deposition of materials from higher on the slope, as well as deposition on the slope by fluvial processes. Commonly soils in this position possess very thick “A” horizons and contain multiple buried soils.
