Fig. 4: Predicted distribution of soil biogeochemistry in response to fire based on machine learning modeling.
From: Fire-driven disruptions of global soil biochemical relationships
The predicted distribution of fire effects on soil C, soil N, soil P, soil microbial biomass, and SOM decomposition (A–E). Latitudinal distribution of soil biogeochemistry in response to fire (F). The R2 values were determined as predicted vs. observed soil C, soil N, soil P, soil microbial biomass, SOM decomposition were 0.45, 0.41, 0.62, 0.56, and 0.43, respectively. A map including information on model uncertainties is provided Supplementary Fig. S12. We also include model validation performance in Supplementary Fig. S13. Micro biomass, soil microbial biomass; SOM decom, soil organic matter decomposition.
