Pedalfer is defined as a formative element in the United States Alfisols soil taxonomic system. Pedalfer is composed of iron oxides and aluminum.

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 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 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.
A soil characteristic of the humid eastern US is Alfisols. Alfisols are typically fertile soils with a clay-rich subsoil that forms in temperate and humid climates. They are common in areas with deciduous forests and agriculture in the eastern United States.
Three common types of soil are sandy soil, clay soil, and loamy soil. Sandy soil has large particles and drains quickly, clay soil has small particles and retains water well, and loamy soil is a balanced mix of sand, silt, and clay that is ideal for plant growth.
Pedalfer is associated with a moist climate, Pedocal with a dry climate and laterite with a wet climate.
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.
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.
