This paper presents a first estimation of net CO2 fluxes from liming of agriculturalsoils in Brazil for the period 1990–2000. The calculation was based on the methodologyproposed by the IPCC, but separately conducted for the five administrative Brazilianregions. The summarized annual CO2emission for Brazil varied from 4.9 to 9.4 Tg CO2yr-¹ with a mean CO2emission of about 7.2 Tg CO2yr-¹. The South, Southeast andCenter region accounted for a least 92% of total emission. Neglecting the emissions from organic soils, the CO2 fluxes from soils (reported under the category 5-D in theNational Inventories of Greenhouse Gas Emission) amounted an updated value of around 51.9 Tg CO2yr-¹ for the period 1975-1995. Uncertainties, projection and other correlated fluxes related with liming are briefly discussed. |
