O objetivo deste estudo é caracterizar uma quantidade e qualidade do carbono orgânico dissolvido (COD) em diferentes condiçõeshídricas nos sistemas de produção de massa e soja no estado de Mato Grosso. Como amostrogens foram realizadas nas estações
úmidas (Fevereiro-março) e nas estações secas (setembro-outubro). Uma concentração de COD e seus bens de fluorescência
óptica medidos a partir de amostras coletadas em diferentes ecossistemas não Estado de Mato Grosso (Cerrado, Pantanal,
Amazônia e ecótono Cerrado / Amazônia). A concentração de COD variou significativamente entre diferentes sistemas e períodos
hidrológicos. O IF (Índice de fluorescência) variaram significativamente apenas entre como estações hidrológicas.
Os valores de IF caracterizam principalmente fontes alóctones de matéria orgânica. Uma análise de SR também indicou significativas entre
locais, ecossistemas e estações hidrológicas. Uma análise das propriedades ópticas sugerem uma grande quantidade de
nossos dispositivos de controle, o que sugere uma presença de lixiviados ea rápida e ineficiente decomposição das plantas
aquáticas. Nas áreas de soja, picos de alta intensidade, foram identificados para o componente de tirosina sem bioma Cerrado. Com
isso, uma concentração de COD, e os índices referentes à sua qualidade, diferiu entre ecossistemas de estudo e períodos hidrológicos.Uma análise das propriedades ópticas sugerem uma grande quantidade de nossos dispositivos de controle, o que sugere uma presença de lixiviados ea rápida e ineficiente decomposição das plantas aquáticas.

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
In particular,
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
