Resumo: | Current studies show a decline in soil biodiversity, which puts at risk future food production since soil organisms play a key role in essential ecosystem functions such as, nutrient cycling and soil fertility, soil carbon sequestration, climate regulation, litter decomposition, erosion, water retention, interaction with plants, among others. This study aims to evaluate how the conversion of a tropical native forest into a field for agricultural production impacts the soil physical-chemical parameters and how these correlates with the abundance of specific groups of microorganisms. The soils analyzed were collected in Guinea-Bissau, at 3 locations with different land uses: a primary forest, an annual crop field (peanut) and a perennial crop field (cashew), during the wet and dry season. We analyzed several soil parameters including pH, water content, N, P and C contents, soil respiration, and soil protein index. Mycorrhizal spore density, analysis of soil PLFA (Phospholipid fatty acids), and qPCR targeting genes involved in N, C and P cycling, were selected for investigating changes in soil microbial diversity. Our results confirm that land use changes alter soil physically and chemically, and its microbial community as well. |

Este estudo visa avaliar como é que a conversão de uma floresta tropical nativa num campo agrícola, altera os parâmetros físico-químicos do solo e como é que estes se correlacionam com a abundância de grupos de microorganismos específicos. Os solos analisados foram recolhidos na Guiné-Bissau em 3 locais com diferentes usos do solo: floresta primária, cultura anual (amendoim) e cultura perene (caju), durante as épocas húmida e seca. A análise dos parâmetros do solo inclui a determinação do pH, respiração do solo, conteúdo hídrico, índice proteico, e conteúdo em nutrientes (P, N e C). Para avaliar as alterações na diversidade microbiana do solo foram selecionadas análises de PLFA (Phospholipid fatty acids), PCR quantitativo de genes envolvidos nos ciclos de nutrientes (N, P e C) e determinação da densidade de esporos de fungos micorrízicos. Os resultados obtidos confirmam que a conversão de floresta para a agricultura altera os parâmetros do solo e as suas comunidades microbianas.Sociedade de Ciências Agrárias de Portugal2024-02-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.33465por2183-041X0871-018XAntónio, RafaelMartins, Ana JoãoCordeiro, InêsFeijão, Eduardo OnofreMatos, Ana RitaMonteiro, FilipaSebastiana, Mónicainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-15T13:19:29Zoai:ojs.revistas.rcaap.pt:article/33465Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T02:38:20.492431Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
