Fig. 4: Two-dimensional partial dependence plots illustrating the predicted soil pyrogenic carbon (PyC) stock (Mg C/ha) as a function of interactions among key predictor variables that influence PyC production and preservation.
From: Pyrogenic carbon contribution to tropical savanna soil carbon storage
The plot shows the effects of interactions between: (A) grass biomass and fire frequency, (B) soil clay and silt content and fire frequency, (C) mean annual rainfall and fire frequency, (D) soil clay and silt content and grass biomass, (E) mean annual rainfall and grass biomass, and (F) soil clay and silt content and mean annual rainfall on soil PyC stock across Kruger National Park, South Africa. Source data are provided as a Source Data file.
