ABSTRACT The “campos” of the Pampa are unique Brazilian ecosystems, which provide key environmental services, including C storage. These grassy ecosystems have been rapidly converted to intensive land-uses, mainly intensive grain crops (soybeans) and Eucalyptus silviculture. These new land-uses could decrease soil C stocks, depending on soil management. This study aimed to assess soil organic carbon (SOC) changes after the conversion of native grasslands to cropland (soybeans/cover crops under no-tillage) and forestry (Eucalyptus). Eight representative sites in this biome were […]

ABSTRACT The expansion of eucalyptus plantations in southern Brazil, especially over regions with natural grasslands, which occurred in the last decade potentially changes total organic carbon and nitrogen in soil. The aim of this study was to test the Century model 4.5 in the simulation of changes in inventories of TOC and TN in the surface layer (0.0-0.2 m) soil in Eucalyptus sp. com different ages in three municipalities in Rio Grande do Sul State, Brazil. Areas adjacent to grasslands […]
