Nutrient cycling, Transgenic organisms, Leaf litterAbstract
The deposition of litter is a major nutrient cycling indicator in forest plantations. The objective of this study was to evaluate dynamics of leaf litter deposition, flow of nutrients from canopy to soil via litter and decomposition of this material in a genetically modified eucalyptus plantation. There were no significant changes in leaf litter production or in nutrients flow due to eucalypts genetic modification. Largest variation was observed between the two studied clones, but they were lower than that commonly observed with changes of silvicultural treatments.
