Global distribution of atmospheric phosphorus sources

The anthropogenic impact of biomass burning in the Amazon is estimated to increase the loss of phosphorus from this phosphorus‐limited region by 25% [Mahowald et al., 2005a], although nonburned regions may be fertilized by biomass burning phosphorus. This is also true for many land ecosystems, and would ultimately increase the phosphorus that
