Mapping ash CaCO3, pH, and extractable elements using principal component analysis
Ash cover in fire-affected areas is an important factor in the reduction of soil erosion and
increased availability of soil nutrients. Thus it is important to understand the spatial
distribution of ash and its capacity for soil protection and to provide nutrients to the
underlying soil. In this work, we aimed to map ash CaCO 3, pH, and select extractable
elements using a principal component analysis (PCA). Four days after a medium to severe
wildfire, we established a grid in a 9× 27 m area on a west facing slope and took ash …
