CO₂ emissions from liming of agricultural soils in Brazil

Global Biogeochemical Cycles (2003)

Martial Bernoux Boris Volkoff Maria da Conceição Santana Carvalho Carlos Eduardo Pellegrino Cerri

This paper presents a first estimation of net CO 2 fluxes from liming of agricultural soils in Brazil for the period 1990–2000. The calculation was based on the methodology proposed by the IPCC, but separately conducted for the five administrative Brazilian regions. The summarized annual CO 2 emission for Brazil varied from 4.9 to 9.4 Tg CO 2 yr −1 with a mean CO 2 emission of about 7.2 Tg CO 2 yr −1 . The South, Southeast and Center region accounted for a least 92% of total emission. Neglecting the emissions from organic soils, the CO 2 fluxes from soils (reported under the category 5‐D in the National Inventories of Greenhouse Gas Emission) amounted an updated value of around 51.9 Tg CO 2 yr −1 for the period 1975–1995. Uncertainties, projection and other correlated fluxes related with liming are briefly discussed.

Brazil's Soil Carbon Stocks

Soil Science Society of America Journal (2002)

Martial Bernoux Maria da Conceição Santana Carvalho Boris Volkoff Carlos Clemente Cerri

Soil organic carbon (C) stocks to a depth of 30 cm were estimated for Brazil on the basis of a map of different soil‐vegetation associations (SVA) combined with results from a soil database. The SVA map was derived by intersection of soil and vegetation maps. The original soil and vegetation classification were simplified to six soil and 15 vegetation categories. The SVA map comprised 21 111 map units (MU) that were spread into 75 different SVA categories. Mean representative C stocks (RCS) of the SVA categories ranged from 1.51 to 41.78 kg C m −2 More than three fourth of all SVA areas had an associated RCS varying between 3 and 6 kg C m −2 Because these data represent sites with native vegetation in the absence of significant disturbances, they represent a valuable baseline for evaluating the effect of land‐use change on soil C stocks for Brazil. In total, about 36.4 ± 3.4 Pg C was stored in the 0‐ to 30‐cm soil layer.
