RESUMO DE SUA PARTICIPAÇÃO:

O 16º Encontro Internacional de Substâncias Húmicas foi extremamente interessante,

pois trouxe discussões e novidades a respeito de temas como o conhecimento da formação e das

características da matéria orgânica, que é de vital importância para a compreensão das suas

propriedades e consequentes interações existentes no solo, sendo fundamental para a área da

sustentabilidade, afinal só é possível preservar efetivamente quando detemos o conhecimento

adequado. O evento reuniu vários especialistas no assunto que apresentaram de forma simples e

direta as novidades em relação ao tema e pontos sobre a conservação da matéria orgânica no

ambiente. Positivamente, minha participação nesse evento foi de grande importância para o

aprimoramento da minha formação acadêmica, estabelecimento de contato com pesquisadores

renomados nesta área, além de me proporcionar uma proveitosa experiência no exterior.

RELATÓRIO DA PARTICIPAÇÃO NO EVENTO:

1. INTRODUÇÃO:

Em condições de clima tropical, o Brasil acumula um volume expressivo de resultados

gerados por grupos de pesquisa em solos, o qual confere ao país uma posição de destaque na

área. Porém a maior parte desses estudos está quase sempre voltada para a fração inorgânica do

solo, ficando a fração orgânica quase sempre em segundo plano.

É de conhecimento geral que a matéria orgânica é responsável por uma série de

benefícios para o solo, seja química, física ou biologicamente. É sabido ainda que a busca

incessante por sistemas sustentáveis e produtivos pode ocorrer através do manejo adequado dos

recursos disponíveis ao mesmo tempo em que satisfaz as necessidades humanas, mantém ou

melhora a qualidade ambiental e conserva os recursos naturais. Gerenciar adequadamente o

ambiente em que vivemos e simultaneamente mantê-lo é um grande desafio que depende, em

escalas distintas, principalmente da compreensão da dinâmica da interação existente entre a

matéria orgânica e o papel que esta desempenha sobre o aproveitamento dos recursos naturais

renováveis, através da ciclagem do carbono, dos nutrientes e da energia presente nos sistemas

agrícolas.

Ainda hoje muito pouco se sabe sobre a natureza e as características da matéria orgânica

nos solos tropicais e subtropicais. Os efeitos das práticas de cultivo, manejo e conservação sobre

a matéria orgânica e, mais especificamente, sobre a formação e distribuição das substâncias

húmicas no solo não se encontram suficientemente estabelecidos Desta forma o conhecimento

aprofundado das características e das condições dessa matéria orgânica é de suma importância

para a compreensão e consequente conservação do solo.

O 16º Encontro Internacional de Substâncias Húmicas trouxe com as seções propostas,

discussões e novidades a respeito de temas como o conhecimento da formação, estrutura e

características da matéria orgânica, que é de vital importância para a compreensão das suas

propriedades e consequentes interações existentes no solo, entre outros temas relevantes já

listados acima.

2. PROGRAMA DO EVENTO:

Em anexo (Anexo 1).

3. RESUMO DE SEU TRABALHO APRESENTADO

Os solos de maior ocorrência nos ambientes genericamente chamados de restinga são os

Espodossolos, caracterizados pela presença de horizonte espódico (Bh ou Bhm). São poucos os

estudos científicos relacionadas à gênese destes solos em regiões tropicais, assim como há

poucos estudos detalhados avaliando as características e a composição química da matéria

orgânica (MO) presente nestes solos, bem como as suas relações com a transcorrência do tempo.

Os municípios paulistas de Cananéia e Bertioga foram selecionados para o desenvolvimento

desta pesquisa devido à presença de diferentes unidades sedimentares e de vegetação

remanescente. A caracterização dos ácidos húmicos (AH) extraídos dos horizontes dos diferentes

perfis de Espodossolos com o emprego de técnicas espectroscópicas como Espectroscopia de

Infravermelho com Transformada de Fourier (FTIR) e Fluorescência, foram realizadas com o

objetivo de se conseguir um maior detalhamento da matéria orgânica (MO) presente nesses solos

e, a partir daí, relacionar os resultados com a estabilidade do carbono e o tempo de residência

médio (TRM) da MO. A principal hipótese testada foi a de que os perfis com a MO com maior

TRM teriam os maiores conteúdos de compostos mais recalcitrantes. Neste âmbito, os principais

resultados relacionados com os objetivos foram: os perfis mais antigos foram os que

apresentaram as maiores concentrações de compostos mais recalcitrantes, principalmente nos

horizontes subsuperficiais (Bh e Bhm), essa inferência pode indicar que com a transcorrência do

tempo a MO presente tende a sofrer alterações na sua composição e se tornar mais recalcitrante.

O resumo expandido apresentado no evento está em anexo (Anexo 2).

4. CONCLUSÕES:

O evento foi muito importante para a minha formação acadêmica, pois possibilitou o

aprimoramento do meu conhecimento em relação ao tema, bem como uma interação direta com

alguns renomados pesquisadores da área. Pude interagir com outros estudantes, de partes

diferentes do mundo, que também estão se formando nessa área do conhecimento. A troca de

experiências, bem como o acúmulo de informações geradas durante o evento foi muito

importante para o meu crescimento acadêmico e pessoal. Dentre os diferentes temas que foram

abordados, houve uma sessão dedicada à área de Estrutura, Formação e Características das

Substâncias Húmicas e Matéria Orgânica, enfocando temas atuais e apresentando perspectivas

futuras da pesquisa, na qual participei por meio de uma apresentação de resumo expandido do

projeto que desenvolvi durante o mestrado e também na forma de pôster.

5. DEMOSTRAÇÃO FINANCEIRA DOS RECURSOS DA FUNDAÇÃO AGRISUS.

Keywords coastal plain; humic substances; mean residence time; Podzol; soil organic matter; spodic horizons Abstract The most common soils that occurred in environments generically called restinga are Podzol that are

characterized by the presence of spodic horizon (Bh or Bhm). There are few scientific studies related to the genesis of these soils in tropical regions, and there are few detailed studies assessing the chemical characteristics and composition of organic matter (OM) present in these soils, as well their relations with time. The cities Cananéia and Bertioga were selected for this research due to the presence of different sedimentary units and remaining vegetation. The characterization of humic acids (HA) was realized using spectroscopic techniques like Fourier Transform Infrared spectroscopy (FTIR) and fluorescence. Samples were extracted from different Podzol horizons in order to achieve more details about the OM present in these soils and relate the results to the stability of carbon and the mean residence time (MRT) of OM. The main hypothesis tested was that the profiles were the OM has less TRM would have the highest contents of more recalcitrant compounds. In this context, the main results related to the objectives were: the older profiles were those with the highest concentrations of more recalcitrant compounds, especially in the subsurface horizons (Bh and Bhm). This inference may indicate that with transcurrent of time MO tends to undergo changes in its composition and become recalcitrant.

Introduction

The OM plays a fundamental role in the Podzol formation process, consisting of humic substances (HS), that are products of oxidative degradation and subsequent humification of OM (Stevenson, 1994). The HS are organic substances chemically complex, amorphous, generally dark, hydrophilic, acidic or partially aromatic (Schnitzer, 1982) composed by compounds that have a wide variety of functional groups (carboxylic, hydroxyl, phenolic, carbonyl, etc.). Part of the HS present in the Bh horizons and Bhm comes from the superficial OM decomposition and some authors have suggested that the TMR estimated by 14C and, consequently, the stability of OM in the soil increases with depth (Paul et al, 1997). The study of SH is possible using spectroscopic techniques such as FTIR (González-Pérez et al., 2008), which permits the study of the structure of HS. Another technique widely used is the fluorescence, by which it is possible to estimate the humification degree (Milori et al., 2002), allowing the elucidation of different aspects of reactivity and chemical structure of OM.

Materials and methods

The profiles called P03, P10 and P30 are located in Cananéia, and the profile P04 in Bertioga. FTIR measurements were performed using methods well

established in the literature (Stevenson, 1994) using tablets with 1 mg of SH and 100 mg KBr. For preparation of the tablets, samples were ground with KBr, packed in a mold and pressed. The spectra were obtained using 16 scans in the range 4000-400 cm-1_,

with spectral resolution of 4 cm and a range of 1 cm-1_.

For fluorescence analysis, the HA extracted from the soil profiles were dissolved in NaHCO3 solution 0.05

mol L-1_{. The spectra were obtained according to the}

methodology proposed by Milori et al. (2002).

For the dating of the soil source material (coastal sediments) by thermoluminescence (TL), the samples were collected with the aid of black PVC pipe inserted horizontally to the ground surface. Both the collection and the dating were performed according to the procedures cited by Tatumi et al. (2003).

Results and discussion

The FTIR spectra of HA extracted from different horizons (A, Bh and Bhm) from the profiles P03, P04, P10 and P30 are shown in Figure 1. Is possible to observe that the spectra of HA extracted from different soil profiles show similarities. There are no significant structural and chemical variations between samples in AH, but it is possible to observe changes in the intensities between the groups in each profile.

Fig. 1 FTIR spectra of HA extracted from the surface horizons (A) and subsurface (Bh and Bhm) from P03, P10, P30

In the spectra of all profiles can be observed that samples of the soil surface have an absorption band between 1170 - 950 cm-1_{, the same being absent in the}

spectra obtained for the subsurface layers Bhm and Bh. This band is assigned to CO stretching of polysaccharides. This result is related to higher content of OM decomposed or even by the presence of microbial activity. It is well know that microorganisms produce polysaccharides during the decomposition of OM (Stevenson, 1994). Another region of the spectrum can be observed only for the samples of the soil surface is between 1660 - 1630 cm-1 _{which is}

attributed to stretching of C = O from amide, which can usually be associated with proteins.

In the spectral region between 3400 - 3300 cm-1_{, the}

absorption due to stretching of the H-bound to OH and NH is stronger in samples from the surperficial horizons, and the lower intensity is observed for Bh horizons. Another variation in intensity is observed in the region between 2940 - 2900 cm-1_{, which is}

assigned to CH stretching of aliphatic groups, being observed a greater intensity of this band in the soil surface, showing a higher concentration of aliphatic. Another variation in depth may be observed in the spectral region between 1725 - 1720 cm-1 _{in which the}

absorption is due to stretching C = O of COOH, being observed a greater intensity in the subsurface horizons. A reverse trend can be observed in the region of the spectrum between 1280 - 1200 cm-1_{, in which}

absorption may be due to CO stretching of aryl-ethers and/or phenolic. The greater intensity of this band occurs in the spectra of samples from subsurface horizons, showing a higher concentration of phenolic compounds in depth. The intensities of the band assigned to aliphatic CH stretching region of the spectrum between 1460 - 1450 cm-1 _{showed a slight}

increase for the samples of surface horizons, with almost imperceptible difference in intensity of this band for the samples of Bh and Bhm horizons

.

In general, the results suggest an increasing degree of humification of OM in depth, as evidenced by the presence of more condensed compounds in the subsurface layers and the highest concentration of aliphatic compounds and the presence of polysaccharides in the surface horizons

.

The results of fluorescence showed that the greatest degree of AH humification were obtained for the Bh horizons of the profiles P03 and P30 in relation to the profiles P10 and P04. The lower degree of humification was determined in HA from the surface horizons of all profiles. The degree of humification is related to the presence of compounds with more complex structures such as aromatic compounds. Looking at Figure 2, the samples that have higher rates of humification are the ones with the higher content of more recalcitrant compounds. Some studies suggest good correlations between the humification rate obtained by fluorescence spectroscopy and other techniques to achieve results directly or indirectly related to the stage of humification of OM evaluated (Milori et al., 2002).

The results obtained by fluorescence showed the same trend of humification was maintained for the different horizons of the different profiles. Comparison between the profiles showed the same results obtained by FTIR. The P30 is the profile that has the highest rates

of humification in relation to others.

By evaluating the results of fluorescence and comparisons made with the results of FTIR and dating was possible to establish a positive relationship between the transcurrent time and humification of the HS. Considering only the TRM of OM was possible to conclude that the older the profile, more stable the OM present in it.

Further investigation about the stability of OM and its comparisons with other factors that influence this process should be made, since there is a need for greater understanding in the concentrations of OM as well its preservation in soil.
