Anais [...]. São José dos Campos: INPE, 2023. p. 339-344. GEOINFO.c2023  aLaboratory methods for soil analysis need to cope with the increasing demand for expedited and widespread georeferenced soil data to support decisions in digital agriculture, digital soil mapping and natural resources monitoring and conservation. A soil visible-near-infrared (VisNIR) and X-ray fluorescence (XRF) spectral library containing data from different Brazilian states is under construction that will (1) support the development of green soil analysis methods, (2) produce data to populate soil geodatabases, and (3) allow fast and accurate soil monitoring. The methods used to build the spectral library and an overview of the current data are presented.  aData analysis  aSoil analysis  aAnálise de Dados  aAnálise do Solo1 aVASQUES, G. M.1 aARAÚJO, T.
