Resumo: | The functioning of ecosystems or agroecosystems is mainly dependent on the soil-litterfall interaction. Thus, the objective of this work was to evaluate the effect of different soil use and management systems on the dynamics of decomposition of plant residues of Azadirachta indica (neem) and Gliricidia sepium (gliricidia). The study was conducted in four land occupation systems, namely: remaining forest, agroforestry, agricultural mandala, and pasture. The decomposition rate was estimated using nylon bags (litter bags), containing 20 g of leaves of A. indica and G. sepium, which were arranged on the soil surface of each area for 18, 36, 54, 72, 90, and 108 days. A completely randomized design was used for each species, considering each area as one treatment, with four replications for each collection. The data were subjected to regression analysis and the means were compared by the Tukey's test (p<0.05). More than 85% and 90% of A. indica and G. sepium plant matters, respectively, had been decomposed after 108 days, regardless of the system evaluated, denoting that these species present high decomposition rates. The phytomass half-life time varied from 16 to 23 days for G. sepium and from 25 to 37 days for A. indica, depending on the land use system. Edaphic temperature, soil water content, and leaf physical and chemical characteristics are weight loss predictors. The results provide important information to enable forest management practices. |

Assim, objetivou-se avaliar a influência de diferentes sistemas de uso e manejo do solo sobre a dinâmica de decomposição dos resíduos vegetais de Azadirachta indica e Gliricidia sepium. O estudo foi conduzido em quatro sistemas de ocupação da terra, sendo eles: remanescente florestal, sistema agroflorestal (SAF), mandala agrícola e pastagem. A taxa de decomposição foi estimada com o uso de sacolas de nylon (litter bags), contendo 20 g de folhas de A. indica e G. sepium, que foram dispostas na superfície do solo de cada área por um período de 18, 36, 54, 72, 90 e 108 dias. Adotou-se um DIC, considerando cada área como um tratamento e quatro repetições a cada coleta, para ambas as espécies. Os dados foram submetidos a uma análise de regressão e as médias foram comparadas pelo teste Tukey (p<0,05). Após 108 dias, mais de 85 e 90% da fitomassa de A. indica e G. sepium, respectivamente, havia sido decomposta, independente do sistema avaliado, indicando que estas espécies apresentam rápida taxa de decomposição. O tempo de meia-vida (T½) do material vegetal variou de 16 a 23 dias no caso da G. sepium e de 25 a 37 dias no caso da A. indica, dependendo do sistema de uso da terra. A temperatura edáfica, o conteúdo de água do solo e as características físico-químicas da fração foliar são preditores da perda de massa. Esses conhecimentos podem fornecer importantes informações que viabilizem práticas de manejo florestal.Universidade Federal Rural do Semi-Árido2022-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1096410.1590/1983-21252023v36n115rcREVISTA CAATINGA; Vol. 36 No. 1 (2023); 135-144Revista Caatinga; v. 36 n. 1 (2023); 135-1441983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10964/11079Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessSilva, João Henrique Constantino SalesBarbosa, Alex da SilvaGomes, Daniel da Silva Aquino, Ítalo de Souza Silva, Janaína Ribeiro da2023-07-27T12:25:06Zoai:ojs.periodicos.ufersa.edu.br:article/10964Revistahttps://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:2024-04-29T09:47:00.729622Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
