Resumo: | Agroecological management can favor the improvement of soil attributes, especially soil organic matter (SOM) and soil aggregation. The objective of the study was to quantify the carbon contents of the humic and oxidizable fractions of SOM of aggregates from different origins from agroecological management systems. Five experimental areas located in the Integrated Agroecological Production System were evaluated: AFS – Agroforestry System; C-SUN – Coffee in full sun; C-SHA – Shaded coffee; AL-FLE – Cultivation in alleys of Flemingia macrophylla with green beans; and NT – No-tillage. The aggregates were separated, identified, and classified as to their origin or formation pathways into biogenic, intermediate, and physicogenic. The carbon contents of the humic fractions fulvic acid (C-FAF), humic acid (C-HAF) and humin (C-HUMF); and oxidizable fractions (F1 and F2, labile; and F3 and F4, recalcitrant) of SOM were determined. The greatest variations in the carbon values of the humic fractions were observed in the aggregates of the AFS, C-SUN and C-SHA systems. In relation to C-HUMF, the highest contents of this fraction were quantified in the biogenic and intermediate aggregates of the C-SUN, C-SHA and AL-FLE systems. The carbon contents of the oxidizable fractions of SOM showed variability between the management systems, mainly for the F1, F2 and F3 fractions in the aggregates under C-SUN and C-SHA. The C-SUN system showed a higher proportion of more humified and recalcitrant fractions of SOM when compared to the C-SHA system. The management practices maids in the agroecological systems of C-SHA, C-SUN and AFS promoted improvements in soil quality. |

O objetivo do estudo foi quantificar os teores de carbono das frações húmicas e oxidáveis da MOS de agregados de diferentes origens de sistemas de manejo agroecológico. Foram avaliadas cinco áreas experimentais localizadas no Sistema Integrado de Produção Agroecológica: SAF – Sistema agroflorestal; C-SOL – Café em pleno sol; C-SOM – Café sombreado; AL-FLE – Cultivo em aleias de flemíngia com vagem; e PD – Plantio direto. Os agregados foram separados, identificados e classificados quanto à sua origem ou vias de formação em biogênicos, intermediários e fisiogênicos. Nestes, foram determinados os teores de carbono das frações ácido fúlvico (C-FAF), ácido húmico (C-FAH) e humina (C-FHUM); e das frações oxidáveis (F1 e F2, frações lábeis; e F3 e F4, frações recalcitrantes). As maiores variações nos valores de carbono das frações húmicas foram verificadas nos agregados sob SAF, C-SOL e C-SOM. Em relação ao C-FHUM, nos agregados biogênicos e intermediários de C-SOL, C-SOM e AL-FLE foram quantificados os maiores teores dessa fração. Os teores de carbono das frações oxidáveis apresentaram variabilidade entre os sistemas de manejo, principalmente para as frações F1, F2 e F3 nos agregados sob C-SOL e C-SOM. No sistema de C-SOL verifica-se maior proporção de frações mais humificadas e recalcitrantes da MOS em comparação à C-SOM. As práticas de manejo empregadas nos sistemas agroecológicos de C-SOM, C-SOL e SAF proporcionaram melhorias na qualidade do solo.Universidade Federal Rural do Semi-Árido2022-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1008310.1590/1983-21252023v36n118rcREVISTA CAATINGA; Vol. 36 No. 1 (2023); 167-176Revista Caatinga; v. 36 n. 1 (2023); 167-1761983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10083/11082Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessRossi, Celeste QueirozPinto, Luiz Alberto da Silva RodriguesMoura, Octávio Vioratti Telles deLoss, ArcangeloPereira, Marcos Gervásio2023-07-27T12:26:34Zoai:ojs.periodicos.ufersa.edu.br:article/10083Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:55.331020Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
