R.  aCarbon and nutrient accumulation in secondary forests regeneration on pastures in Central Amazonia.  c2004  aDetermining nutrient constraints to regrowth and the status of secondary vegetation is an important step in managing and/or enhancing abandoned site rehabilitation. We examined the dual roles of SF to rehabilitate site productivity and to increase C sinks and investigated potential soil nutrient limitations to these two processes. We examined aboveground and soil C accrual and nutrient stocks in degraded pastures that had been abandoned for a varying number of years. Our objective was to study the influence of regenerating vegetation on C and nutrient budgets following pasture abandonment. We hypothesized that C and N pools would recover with time following post-burn volatilization, while other nutrients would be redistributed form below-to aboveground pools resulting in reduced soil pools.  aAmazonia  aCarbono  aFloresta Secundaria  aNutriente  aSolo  aAmazonas  aBrasil1 aRONDON, M.
