“…Por outro lado, onde foi adicionado solo superficial, já na avaliação feita em 2000, pode-se considerar que a comunidade da fauna edáfica já estava estabelecida. Nessa situação, como a degradação inicial foi muito intensa, ocorrendo a retirada de toda a vegetação, solo e subsolo, a colonização natural pode ser lenta, sendo assim o processo de estabelecimento da fauna edáfica é acelerado quando do retorno do solo superficial, trazendo propágulos e mais fertilidade ao substrato (MARTINS et al, 2019).…”

O trabalho objetivou acompanhar a colonização da comunidade da fauna edáfica, como indicador de qualidade de ambiente, após a revegetação de áreas alteradas pela atividade de mineração de bauxita, em Porto Trombetas, Pará. As amostragens foram realizadas nos anos 2000, 2002, 2003, 2004 e 2008 em plantios de diferentes idades, e com diferentes arranjos de espécies, majoritariamente nativas do bioma, implantadas sobre subsolo com e sem adição de solo superficial. Os organismos da fauna edáfica foram capturados em armadilhas do tipo pitfall e triados no laboratório. Os parâmetros usados para avaliação foram a abundância, a riqueza, os índices de diversidade de Shannon e Equabilidade de Pielou e o padrão de colonização dos indivíduos da fauna do solo. De modo geral, em todos os plantios sobre o estéril, os grupos que apareceram em maior abundância foram Collembola, Formicidae e Coleoptera. A idade do plantio e a adição de solo superficial foram fatores determinantes na recomposição da comunidade edáfica, que se mostrou mais intensa nos plantios mais antigos. Nessas áreas, o desenvolvimento da vegetação levou à maior colonização e à melhor estruturação da comunidade de fauna edáfica, aumentando sua diversidade e o restabelecimento de processos ecológicos.

“…A recent investigation showed that, in comparison with pasture systems, analog agroforests not only enhance soil fertility, but also the complexity of the soil faunal community, as evidenced by an increase in the total abundance, mean and total richness, evenness, and diversity of soil taxa (Camara et al, 2020). However, few studies have examined the influence of natural succession in analog agroforestry systems on soil organic matter fractions, aggregate stability, arbuscular mycorrhizal fungi (AMF) (Martins et al, 2019), and easily extractable glomalin-related soil protein (EE-GRSP).…”

Study aimed to (i) assess the impact of analog agroforestry (agrofor) on arbuscular mycorrhizal fungi (AMF), easily extractable glomalin-related soil protein (EE-GRSP), soil organic matter (SOM), and aggregate stability compared with a pasture system and (ii) investigate the chemical, physical and OM properties that explain the differences in soil microbiology between sites. The study was conducted in an agrofor and pasture area. Soil samples were collected in the dry season. A total of 12 AMF taxa were identified. Mean richness was positively correlated with soil pH, Mg 2+ , sum of bases (SB) and moisture. Mean richness and diversity were higher in the analog agroforestry site. Pasture soil had higher EE-GRSP content and spore abundance, variables that were found to be positively correlated with soil temperature, P, K + , and H + Al. EE-GRSP also showed a positive correlation with total organic carbon. Aggregate stability was greater in soil under analog agroforest than pasture. SOM properties did not differ between sites. It is concluded that agrofor changes the evaluated soil physical and microbiological attributes, and the microbiological attributes are influenced by the pH, Mg +2 , K + , SB, P, H+Al, soil moisture and TOC.

“…In this context, agroforestry systems (SAFs) are likely a promising alternative, with the plantation of a consortium of both native and exotic tree species for wood production, while also conserving natural resources (Lenci et al, 2018). Accordingly, SAFs are responsible for a number of benefi ts when used for wood production, including an improvement in the constituent characteristics of wood, as well as ecological benefi ts such as reduced soil degradation (Martins et al, 2019), thus reducing the impacts on the surrounding environment.…”

The cultivation of native and exotic species intercropped in an agroforestry system raises the interest for information on the properties of wood. Therefore, different methods are being tested to improve the technological properties of this material, including drying, which causes changes in the physical and mechanical properties of the wood. The present study investigated the influence of drying on the physical and mechanical properties of wood from tree species grown in an agroforestry system. Parapiptadenia rigida (Benth.) Brenan, Peltophorum dubium (Spreng.) Taub., Eucalyptus grandis W. Hill × Eucalyptus urophylla S.T. Blake (hybrid), and Schizolobium parahyba (Vell.) S.F.Blake were the species selected for the study. Three 9-year-old individuals of each of the species were obtained from an agroforestry system. Thirty wood samples (2.5 × 2.5 × 41 cm) were extracted from each species. The wood samples were divided between temperature treatments; 6 samples were used for each heat treatment (control, 120, 150, 180, and 210 °C), which were then dried for two hours in an oven (with forced air circulation). Following the heat treatment, the mechanical properties of wood samples were evaluated to determine the modulus of elasticity and rupture, the tension in the proportional limit, and maximum force according to the ASTM D-143-94 (2000) standard. Finally, the physical properties of the retractability of the wood samples were evaluated according to the NBR 7190 (ABNT, 1997) standard. Specimens used to analyze this variable came from sections of the wood (sample dimensions: 2.5 × 2.5 × 5 cm) not affected by the static bending test. Our findings indicate that, for all species investigated in this study, drying alters the physical and mechanical properties of the wood, with the most significant changes occurring at temperatures between 120 and 180 °C.
