Resumo: | The objective of the present work was to quantify soil carbon stock at different depths under agroecosystems and secondary vegetation area. The research was developed in the localities Caiana and Mata Redonda, belonging to the municipality of Remígio-PB. Four areas were selected, characterized according to the cultivation system in: conventional system, pasture, agroforestry system (SAF) and area with secondary vegetation. The experiment was carried out in a completely randomized design with a factorial arrangement [(3x3)+1], being the factors: cropping system (conventional, pasture and agroforestry system), depth (0-20; 20-40 and 40-60 cm) and an additional treatment corresponding to secondary vegetation. Organic carbon was extracted using the Walkley-Black method (oxidation-reduction), in which organic matter is oxidized using potassium dichromate. Organic matter was obtained by multiplying the carbon content by the constant 1,724. To determine the soil density (Ds) samples were collected with the aid of volumetric rings of 100 cm3 of internal volume from the layers 0-20, 20-40 and 40 to 60 cm. After collecting the samples, still in the field, the excess soil was removed from the edges of the rings, with the aid of a stylet. Then, the volumetric rings were sealed with cling film to avoid possible damage and deformation. Crop systems cause greater changes in chemical characteristics and soil carbon stock than secondary vegetation. The carbon stock is higher in the surface layer (0-20 cm) and in environments where the characteristics are closer to equilibrium, decreasing in depth. |

La investigación se desarrolló en las localidades Caiana y Mata Redonda, pertenecientes al municipio de Remígio-PB. Se seleccionaron cuatro áreas, caracterizadas según el sistema de cultivo en: sistema convencional, pastizal, sistema agroforestal (SAF) y área con vegetación secundaria. El experimento se realizó en un diseño completamente al azar con arreglo factorial [(3x3)+1], siendo los factores: sistema de cultivo (convencional, pastura y sistema agroforestal), profundidad (0-20; 20-40 y 40-60 cm) y un tratamiento adicional correspondiente a la vegetación secundaria. El carbón orgánico se extrajo mediante el método de Walkley-Black (oxidación-reducción), en el que la materia orgánica se oxida utilizando dicromato de potasio. La materia orgánica se obtuvo multiplicando el contenido de carbono por la constante 1,724. Para determinar la densidad del suelo (Ds) se recolectaron muestras con ayuda de anillos volumétricos de 100 cm3 de volumen interno de las capas 0-20, 20-40 y 40 a 60 cm. Después de recolectar las muestras, aún en campo, se eliminó el exceso de suelo de los bordes de los anillos, con la ayuda de un estilete. Luego, los anillos volumétricos se sellaron con film transparente para evitar posibles daños y deformaciones. Los sistemas de cultivo provocan mayores cambios en las características químicas y las reservas de carbono del suelo que la vegetación secundaria. El stock de carbono es mayor en la capa superficial (0-20 cm) y en ambientes donde las características están más cerca del equilibrio, decreciendo en profundidad.O objetivo com o presente trabalho foi de quantificar o estoque de carbono do solo em diferentes profundidades sob agroecossistemas e área de vegetação secundária. A pesquisa foi desenvolvida nas localidades Caiana e Mata Redonda, pertencentes ao município de Remígio- PB. Foram selecionadas quatro áreas, caracterizadas de acordo com o sistema de cultivo em: sistema convencional, pastagem, sistema agroflorestal (SAF) e área com vegetação secundária. O experimento foi conduzido em delineamento inteiramente casualizado com arranjo fatorial [(3x3)+1], sendo os fatores: sistema de cultivo (convencional, pastagem e sistema agroflorestal), profundidade (0-20; 20-40 e 40-60 cm) e um tratamento adicional correspondente a vegetação secundária. O carbono orgânico foi extraído através do método de Walkley-Black (oxi-redução), em que a matéria orgânica é oxidada com o uso de dicromato de potássio. A matéria orgânica foi obtida pela multiplicação do teor de carbono pela constante 1,724. Para determinar a densidade do solo (Ds) foram coletadas amostras com o auxílio de anéis volumétricos de 100 cm3 de volume interno das camadas de 0-20, 20-40 e 40 a 60 cm. Após a coleta das amostras, ainda no campo, foi retirado o excesso de solo dos bordos dos anéis, com o auxílio de um estilete. Em seguida, os anéis volumétricos foram vedados com papel filme para evitar possíveis danos e deformações. Os sistemas de cultivo provocam maiores alterações no estoque de carbono do solo que a vegetação secundária. O estoque de carbono é maior na camada superficial (0-20 cm) e nos ambientes onde as características estão mais próximas às de equilíbrio, decrescendo em profundidade.Research, Society and Development2022-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3384010.33448/rsd-v11i11.33840Research, Society and Development; Vol. 11 No. 11; e545111133840Research, Society and Development; Vol. 11 Núm. 11; e545111133840Research, Society and Development; v. 11 n. 11; e5451111338402525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/33840/28695Copyright (c) 2022 Dayseana Carneiro Rufino; Manoel Alexandre Diniz Neto; Thiago de Sousa Melo; Lucas Borchart Bandeira; Márcia Daniele Pereira da Silva; Leandro Antônio de Bulhões; Belísia Lúcia Moreira Toscano Diniz; Evandro Franklin de Mesquitahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRufino, Dayseana Carneiro Diniz Neto, Manoel AlexandreMelo, Thiago de Sousa Bandeira, Lucas Borchart Silva, Márcia Daniele Pereira da Bulhões, Leandro Antônio de Diniz, Belísia Lúcia Moreira Toscano Mesquita, Evandro Franklin de 2022-09-05T13:24:46Zoai:ojs.pkp.sfu.ca:article/33840Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:49:22.756793Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
