Resumo: Abstract: The study aimed to estimate the soil organic carbon (SOC) stock in the citrus belt of São Paulo and West/Southwest Minas Gerais States (The main Brazilian Citrus Belt - BCB) and to compare the estimated data with measured data from on-farm orange groves and environmental conservation areas. The Brazilian SOC map was used to estimate SOC stock (topsoil; 0 to 30 cm) across 496,720 hectares of the BCB. Carbon content and soil bulk density were analyzed to determine the C stocks in orange groves and native vegetation areas of representative citrus farms in five sectors of the BCB. Approximately 19,761 million Mg of C was estimated, with 67% stored in orange groves (39.4 Mg C ha- 1) and 33% in environmental conservation areas (40.59 Mg C ha-1). On-farm SOC analysis in orange groves (32.27 Mg C ha-1) and native vegetation areas (40.1 Mg C ha-1) is highly valuable for understanding SOC stock estimation results provided by the digital SOC map.
