Soil that is characterized by an abundance of aluminum and iron oxides. Pedalfers are common in humid regions and are deposited in the B horizon of ABC soils, through leaching
Pedalfer is defined as a formative element in the United States Alfisols soil taxonomic system. Pedalfer is composed of iron oxides and aluminum.
Pedalfer is associated with a moist climate, Pedocal with a dry climate and laterite with a wet climate.

Pedalfer soil is typically found in temperate regions with a moderate amount of rainfall. It is commonly found in the eastern United States, parts of Europe, and Asia. This type of soil is characterized by its reddish-brown color and high fertility.
Pedalfer soils are typically found in regions with moderate to high precipitation levels and cool temperatures, such as in the eastern United States. They are characterized by their high iron and aluminum content and are usually fertile for agriculture when properly managed.
Pedalfer soil formation involves the accumulation of iron and aluminum oxides in the B horizon, which is enriched in clay minerals. This process occurs in humid climates where organic matter decomposition and leaching of soluble minerals is common. The resulting soil is typically red or brown in color and has good fertility.
Illuviation refers to the process where materials such as clays, organic matter, and other dissolved substances accumulate in the B horizon of the soil profile. In pedalfer soils, the accumulation of illuviated materials leads to the development of specific characteristics such as a dark color, high clay content, and enriched fertility due to the concentration of minerals and organic matter.
The main factor that accounts for the differences between pedalfer, pedoc, and laterite soils is their composition and formation processes. Pedalfers are rich in iron and aluminum, forming in humid, temperate regions with well-drained soil. Pedocs are characterized by their calcareous content and form in semi-arid to arid regions. Laterite soils are highly weathered and rich in iron and aluminum oxides, forming in tropical regions with high rainfall and intense weathering.
Climate is the factor that accounts for most of the differences between pedocal, pedalfer, and laterite soils. Pedocal soils are found in arid or semi-arid climates, pedalfer soils are typical in humid climates with high rainfall, and laterite soils develop in humid tropical climates with intense weathering. These climate conditions influence the processes of soil formation and the dominant minerals present in each soil type.
The main factor accounting for the differences between pedalfer, pedocal, and laterite soils is the varying climate conditions where they form. Pedalfers develop in humid regions with abundant rainfall and are rich in aluminum and iron oxides. Pedocals form in drier regions with more evaporation, leading to the accumulation of calcium carbonate. Laterite soils develop in hot and wet tropical climates with intense weathering, resulting in the leaching of nutrients and the formation of iron and aluminum compounds.
