Resumo: | Several anthropic activities provide wastes and rejects in ecosystems mainly aquatic, and usually inadequately. As a result there can be increases in the amount of nutrients mainly of phosphorus and nitrogen making a medium conducive to Cyanobacteria blooms. The objective of study was identify and quantify the phytoplankton community and water nutrients from June to November 2015 at three points in one branch of Rio Grande, Frutal-MG, to verify the possibility of using water for irrigation of agroecological crops of olerícolas. At the three sampling points the variables temperature, conductivity, dissolved oxygen and pH were in accordance with CONAMA 357/2005. The nutrients (total phosphorus, orthophosphate, nitrate, nitrite and total ammoniacal nitrogen) presented low concentrations and remained in compliance with the resolution in all sites and periods analyzed. The abundance of phytoplankton was divided into 3 large groups: Bacillariophyceae, Chlophyceae and Cyanobacteria. Large amounts of cyanobacteria were observed in the samples, posing a risk due to the potential of these algae to produce toxins. To be used in irrigation of agroecological crops, it is necessary that the water in question goes through treatment. |

Como resultado, pode-se haver incrementos da quantidade de nutrientes, principalmente de fósforo e nitrogênio, tornando um meio propício para florações de Cyanobacteria. Objetivou-se com esse estudo identificar a comunidade fitoplanctônica e nutrientes da água em um braço do Rio Grande, Frutal, Minas Gerais, para verificar a possibilidade de uso da água na irrigação de cultivo agroecológico de olerícolas. Nos três pontos amostrais as variáveis temperatura, condutividade, oxigênio dissolvido e pH estavam em conformidade com a CONAMA 357/2005. Os nutrientes (fósforo total, ortofosfato, nitrato, nitrito e nitrogênio amoniacal total) apresentaram baixas concentrações e mantiveram-se em conformidade com a resolução em todos os pontos e períodos analisados. A abundância do fitoplâncton ficou dividida em 3 grandes grupos: Bacillariophyceae, Chlorophyceae e Cyanobacteria. Grandes quantidades de cianobactérias foram observadas nas amostras, trazendo risco devido ao potencial dessas algas para produzir toxinas. Para ser utilizada na irrigação de cultivo agroecológico, é necessário que a água em questão passe por tratamento.Editora Verde2018-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfapplication/pdfapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/571410.18378/rvads.v13i3.5714Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 No. 3 (2018); 348 - 355Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 Núm. 3 (2018); 348 - 355Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 13 n. 3 (2018); 348 - 3551981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/5714/5898https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5714/5900https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5714/9597https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5714/9598Copyright (c) 2018 Ana Carolina Roque Cardoso et al.info:eu-repo/semantics/openAccessCardoso, Ana Carolina RoquePeixoto, Pedro GomesMillan, Rodrigo Ney2021-06-14T13:14:02Zoai:ojs.gvaa.com.br:article/5714Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:27.303245Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
