Map of total phosphorus content in native soils of Brazil

Knowledge of the distribution total phosphorus (P) content in native soils provides information on management ecosystem, land capability for agriculture, environmental quality, and biodiversity conservation. We mapped spatial P concentrations topsoils (0-30 cm) uncultivated (native) areas Brazil. obtained data southern, south-eastern, north-eastern regions from reports exploratory projects developed between 1960s 1970s by EMBRAPA RADAM Brazil Project. estimated central-western northern relationship soil properties (Fe, Al, C clay content), based Soil varied widely (< 25 to > 500 mg kg–1) all Higher (> were observed southern region compared most rest country 200 kg–1), while Cerrado (Central), Amazon (North) Caatinga (Northeast) biomes are very poor P. This first national map a valuable baseline understanding historical patterns agriculture expansion It allows quantifying effect future cropping systems available legacy P, targeting regional soil-crop specific strategies optimization ecosystem services, mitigating potential risk due transference water bodies.
