1. a soil type characterized by the accumulation of aluminum and iron oxides, typically found in humid climates with heavy rainfall
Usage: geology; soil science

Examples

• The pedalfer soils of the eastern United States are rich in iron and aluminum compounds.
• Heavy rainfall in tropical regions often leads to the formation of pedalfer soils.
• Scientists studied the pedalfer deposits to understand the region’s climate history.
• The red color of many pedalfer soils comes from iron oxide accumulation.
• Farmers in pedalfer regions often need to add lime to reduce soil acidity.
• The forest floor showed typical pedalfer characteristics with its leached upper layers.
