An integrated approach to studying the genesis of andic soils in Italian non-volcanic mountain ecosystems

摘要: Abstract Over recent decades, andic soils have been increasingly found in non-volcanic mountain ecosystems (NVME) many parts of the world. In Italy, this type soil has proved to be greatly affected by aeolian deposits and widely distributed geographically. However, there are still open questions, especially regarding genesis these soils. This paper focuses on five representative pedons taken from NVME. Soil forming processes relationships between underlying bedrock were investigated using an integrated approach including geochemical, magnetic, mineralogical, micromorphological particle size distribution (PSD) analysis. The 5 showed character similar morphology micromorphology (e.g. silt illuviation, pedorelicts), as well large differences terms reaction clay mineralogy. analysis vertical C, Al Fe extracted pyrophosphate along with related geochemical indices C p /Al ) enabled us indicate andosolization main process formation exclude podzolization.
