SOILS OF THE WORLD

Tropical Red Soils are found in

Areas with hot and wet climatic conditions

These areas are called

Tropical or equatorial zones

Ex. (tropical/equatorial)

Amazon Basin in South America and Indonesia

High temp + heavy rainfall leads to

Intense chemical weathering

Constant supply of humus due to

Rapid vegetation and continuous leaf fall

High temps lead to

Rapid decomposition of plant litter

Chemical Weathering

Acidic Soils

Human Interference with Soils

Over-exploitation is harmful

Soil erosion from

Intensive farming can deplete nutrients (desertification)

Deforestation

Conversion from forest to non-forest land

Removal of trees is used for

Economic purposes (furniture + agriculture)

Removes humus which

Harms fertility

Too exposed leads to

Soil erosion

Lack of vegetation leads to

Mass movement and flooding

Solution

Forest management and reafforestation (replacing trees)
