RESUMO DE SUA PARTICIPAÇÃO:
O “ASA, CSSA e SSSA International Annual Meetings”, que ocorre todo ano, é um evento
muito amplo que conta com a presença maciça de pesquisadores consagrados das mais diversas
partes do mundo. Nesse aspecto foi possível ter uma visão geral dos temas que estão atualmente
sendo investigados pela comunidade cientifica mundial, onde meu foco foi observar os trabalhos
relacionados aos processos de acúmulo/perda de carbono no solo. Muitas pesquisas interessantes
nessa área estão sendo desenvolvidas e pude, com esse evento, ter algumas idéias de projetos
futuros que possam ser desenvolvidos de forma a entender melhor esses processos.
Além da minha visão de outros trabalhos, foi importante observar através da apresentação
do pôster que alguns pesquisadores ficaram muito interessados no nosso trabalho (desenvolvido
com apoio da Fundação Agrisus), principalmente por se tratar de um ambiente subtropical e
tropical, onde tem-se poucos resultados no tema estudado.
RELATÓRIO DA PARTICIPAÇÃO NO EVENTO:
1. INTRODUÇÃO:
Esse ano foi a minha primeira participação no “ASA, CSSA e SSSA International Annual
Meetings”, o qual é realizado anualmente. Esse evento geralmente conta com a presença de mais de
4000 pessoas, entre pesquisadores, educadores e estudantes, o que possibilita uma troca de
informação com as mais diversas áreas de conhecimento do campo agronômico. A experiência
obtida com esse tipo de reunião é muito positiva, pois dá a oportunidade de estudantes que estão
começando sua vida científica, dividirem a sala de apresentações com pesquisaodres renomados na
sua área. Além disso, na sessão de pôsteres, é possivel trocar idéias muito construtivas com também
professores e pesquisadores renomados, além de outros estudantes das mais diversas Universidades.

3. RESUMO DE SEU TRABALHO APRESENTADO
Biomass-C Transport into Soil Carbon Pools in Brazilian Oxisols: A Long Term Incubation
Study.
Food production has been impacted the carbon (C) cycles, and its depletion is principal factor of
soil degradation. Thus, aims of this study were to assess impact of different biomass-C rates added
to the soil on soil respiration and C transport into three soil layers. Samples of Oxisols were
collected for 0-20, 20-40 and 40-100 cm layers from several long-term experiments conducted in
tropical and subtropical regions, and were incubated for 20 months. The incubation procedure
comprised of the input of 0, 5, 10 and 20 g C kg-1 soil. After 20 months, the highest soil respiration
was measured in treatment receiving the highest C-residues inputs for all sites and soil layers.
However, the C-CO2 release was also related to the antecedent SOC concentration (y=41.5x +
4882; R2=0.7***). The highest soil respiration in the control treatment (e.g. 0 g C kg-1 soil)
occurred in Ponta Grossa site because the soil had high clay and C contents. The high rate of soil
respiration was observed on the first days after the input of fresh residues. Thus, regular inputs of
residues are needed to sustain the microbial activity in soil. The linear relationship between
biomass-C addition and SOC concentration was observed for all sites and all depths. Furthermore,
the highest SOC accumulation was observed at the 40-100 cm depth, increasing in 1.6, 0.8 and 0.6 g
Kg-1 in 20 months to Londrina, Lucas do Rio Verde and Ponta Grossa respectively, indicating high
C deficit, or sink capacity. The data support the conclusion that the high residues input and crop
managements are important to increase C input in deep layers, and the strategy has a vast potential
to enhance SOC sequestration by managing crops which can add C into deep layers.
