Soil Taxonomy & Diagnostic Horizons of soil - 9 Epipedons

TOPIC - Soil Taxonomy & Diagnostic Horizons of soil - 9 Epipedons

Course title - Fundamentals Of Soil Science

Hello there,
In this video, we'll be studying a very important topic i.e. Soil classification.
You may know that it's a quiet long topic.
I'll be covering this topic as -

What is soil classification?
Evolution of soil classification systems.
The early systems of soil classification
Economic classification of soil
Physical classification of soil
Chemical classification of soil
Geological classification of soil
Physiological classification of soil

Dokuchaev's Genetic system of soil classification
Zonality concept
Zonal Intrazonal And Azonal soils
Normal transitional and abnormal soils

Marbut's morphogenetic classification system
Baldwin and associates genetic system of Classification

What is soil taxonomy?
History about soil taxonomy
Soil taxonomy as a comprehensive system of soil classification
Diagnostic horizons in soil taxonomy

Diagnostic horizons and there types
Epipedon and endopedons
Difference between Epipedon and endopedons
Details about Epipedon and endopedons
9 Epipedon or surface horizons

The eight important epipedons are anthropic, folistic, histic, melanic, mollic, ochric, plaggen and umbric epipedons.

The important diagnostic subsurface horizons are agric, albic, argillic, calcic, cambic, glossic, gypsic, kandic, natric, oxic, petrocalic, petrogypsic, placic, salic, sombric and spodic horizons.
Soil classification is the distribution of soil based on its characteristics


12 soil orders in soil taxonomy
Entisols, Inceptisols, Andisols, Mollisols, Alfisols, Spodosols, Ultisols, Oxisols, Gelisols, Histosols, Aridisols and Vertisols

8 types Soils of India -

Alluvial Soil
Black Cotton Soil
Red & Yellow Soil
Laterite Soil
Mountainous or Forest Soil
Arid or Desert Soil
Saline and Alkaline Soil
Peaty and Marshy Soil

Soil moisture regime -
Udic
Ustic
Aridic (or Torric)
Xeric

Classes of Soil Temperature Regimes

Cryic
Frigid
Mesic
Thermic
Hyperthermic
Isofrigid
Isomesic
Isothermic
