Sustainable Management of Volcanic Ash Soils

Globally, volcanic soils (Andosols or Andisols) cover 0.84% of the Earth’s terrestrial surface (Dahlgren et al., 2004). Around 60% of the area covered by volcanic soils is in tropical countries (Takahashi and Shoji, 2001). These soils possess very distinctive characteristics defined as andic propert...

Description
Summary:Globally, volcanic soils (Andosols or Andisols) cover 0.84% of the Earth’s terrestrial surface (Dahlgren et al., 2004). Around 60% of the area covered by volcanic soils is in tropical countries (Takahashi and Shoji, 2001). These soils possess very distinctive characteristics defined as andic properties (IUSS, 2015) that distinguish them from other soils in the world. These soils are of major relevance in areas with intense tectonic movements, such as The Circum-Pacific Ring of Fire (USGS, 2018) affecting areas as New Zealand, Japan, the Philippines, Aleutian Islands, Alaska, North America and South America among others (Figure 1). A nivel mundial, los suelos volcánicos (Andosoles o Andisoles) cubren el 0,84% de la superficie terrestre (Dahlgren et al., 2004). Aproximadamente, un 60% de la superficie cubierta por suelos volcánicos se encuentra en países tropicales (Takahashi y Shoji, 2001). Estos suelos poseen características muy distintivas definidas como propiedades ándicas (IUSS, 2015) que los distinguen de otros suelos del mundo. Estos suelos son de gran relevancia en áreas con intensos movimientos tectónicos, como el Cinturón de Fuego del Pacífico (USGS, 2018) que afecta a áreas como Nueva Zelanda, Japón, Filipinas, Islas Aleutianas, Alaska, América del Norte y América del Sur entre otras (Figura 1).
