Perspective of soil carbon sequestration in Chilean volcanic soils

open access: yesnpj Materials Sustainability
We analysed a large dataset consisting of 457 soil profiles of Andisols and Ultisols of volcanic origin compared to 60 non-volcanic soils. We hypothesised that soil pH has a greater impact on the development of Al-organomineral complexes in volcanic ...

Physicochemical variability of Andisols in Colombian monogenetic volcanic fields under diverse management systems

open access: yesRevista de Ciencias Agrícolas
Andisols are highly productive soils formed by the progressive weathering of volcanic products. Two volcanic areas of Colombia were evaluated to compare soil characteristics and the influence of volcanic products on regional soil components.
