Os resíduos gerados na exploração de carvão mineral e no curtume de peles são produtos potencialmente poluentes em várias regiões do Brasil, principalmente nos estados do Rio Grande do Sul e de Santa Catarina. O objetivo do trabalho foi avaliar a taxa de degradação e a variação de nitrogênio mineral e pH do solo pela aplicação de resíduos de curtume e carbonífero no solo. O experimento foi conduzido em frascos respirométricos em um Argissolo Vermelho Distrófico típico que estava sob campo nativo. Foram aplicados oito tratamentos sendo testados o lodo de efluentes (LC) e a serragem cromada (SC) de curtume e resíduo carbonífero (RC). A adição de lodo de curtume (LC + PK) promoveu uma degradação de 23,3% do carbono adicionado após 88 dias de incubação. O lodo de curtume foi eficiente para aumentar o pH do solo a pH 6. O lodo de curtume pode ser utilizado para a neutralização da acidez do solo gerada pelo descarte de resíduo carbonífero contendo alto teor de enxofre reduzido. A serragem cromada pode ser descartada no solo, desde que haja uma calagem e adubação com nitrogênio, fósforo e potássio em quantidades adequadas para o desenvolvimento das culturas. O resíduo carbonífero apresenta grande potencial de acidificação do solo e baixa taxa de decomposição.Downloads

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.
