DOI: 10.1038/s41467-026-68340-4 The conversion of Brazil's native biomes into agricultural areas has resulted in an estimated loss of 1.4 billion tons of soil carbon. This amount is equal to the emission of 5.2 billion tons of carbon dioxide (CO₂) equivalent, a unit of measurement used to standardize the emission of different greenhouse gases, and was calculated based on data collected from studies conducted over the past 30 years. These findings are from a study published in the journal Nature Communications by researchers from the Luiz de Queiroz School of Agriculture at the University of São Paulo (ESALQ-USP) and the State University of Ponta Grossa (UEPG), as well as Embrapa Agricultura Digital, one of the decentralized units of the Brazilian Agricultural Research Corporation (EMBRAPA).…
