Conteúdo: |
Soil organic matter comprises several fractions, such as the light fraction (or particulate organic matter), microbial biomass, water-stable organics, and humus (stabilized organic matter). It is considered one of the more useful indicators of soil quality, because it interacts with other numerous soil components, affecting water retention, aggregate formation, bulk density, pH, buffer capacity, cation exchange properties, mineralization, sorption of pesticides and other agrichemicals, color (facilitate warming), infiltration, aeration, and activity of soil organisms. It is the interaction of the various components of a soil that produces the net effects and not organic matter acting alone. According to recent concepts, sustainable land use must be assessed in terms of its impact on the soil organic carbon (SOC) pool. A non-negative trend in SOC poll would imply a sustainable land use/soil management system. All other factors remaining the same, a sustainable system would enhance SOC content. Because SOC can have tremendous effect on the capacity of a soil to function, it has been recommended as a basic component in every minimum data set for assessing soil quality. Therefore, the aim of this report is to assemble and synthesize the available information on soil carbon stocks and changes due to modifications on land use and management practices in Brazil. For instance, the focus will be on the following systems: i) conversion forest-to-pasture in the Brazilian Amazon and ii) burning versus unburning sugarcane harvesting system in Brazil.
