These high-level categories are typically arranged in a hierarchy where broader groups are subdivided into more specific classes. The primary goal is to create a logical hierarchy that reflects the soil's formation, composition, and potential.
Understanding Soil Classification Hierarchy and Subdivision Levels
These are specific layers within the soil profile that exhibit distinct physical or chemical properties resulting from soil formation processes. Foundations of Soil Taxonomy The taxonomic classification of soil is a systematic method used to categorize soils based on their observable properties and inferred characteristics.
Major Soil Orders and Their Distinction Most classification systems recognize a small number of broad soil orders that represent fundamental climatic and biotic processes. This ensures that similar soils are grouped together, regardless of their geographic location, facilitating comparative analysis across different regions.
Understanding Soil Classification Hierarchy and Subdivision Levels
Taxonomists look for features such as accumulation of clay, organic matter, or iron and aluminum oxides, or distinct changes in color and structure. Soil Order Key Diagnostic Feature Typical Environment Entisols Lack of significant horizon development Recent deposits (floodplains, sand dunes) Inceptisols Weak horizon development Young soils on steep slopes or mesic climates Mollisols Dark, high-organic matter surface horizon Temperate grasslands Ultisols Clay accumulation (argillic horizon), base-poor Warm, humid regions with significant weathering Oxisols Highly weathered, low cation exchange capacity Tropical and subtropical wet environments Integration of Soil Properties.
