Laboratory of Conservation and Dynamics of Volcanic Soils


This study seeks to propose an early indicator of carbon sequestration capacity in volcanic soils of southern Chile. For this purpose, the priming effect will be evaluated as a possible tool, using stable isotopes (13C and 15N).

This study is financed by Anagra-Chile SA, and will be carried out during three consecutive years in production agrosystems with permanent pastures and crop rotation under conventional and zero tillage, established in two volcanic soils of southern Chile (Andisol and Ultisol). In addition, chemical methods and biological indicators will be used to quantify the impact of amorphous clays and organo-mineral complexes on carbon mineralization and stabilization in the different soils. In addition, potential greenhouse gas (CO2) emissions and economic impacts in the value chain will be estimated.
