“…Therefore, the carnauba processing residue increased the contents of more recalcitrant fractions of the SOM and increased POC contents. Studies have shown that this increase caused by a longer time of management with carnauba processing residue, since its decomposition presents different stages due to the protection of ceriferous components, high lignin contents, and large particles, which decrease the biodegradation process and the area available to decomposer agents (KIEHL, 1985;IWATA et al, 2020;SILVA et al, 2020).…”

The objective of this work was to evaluate the variation in total and particulate organic carbon contents, carbon vertical stratification, and sensitivity index of organic matter fractions in soils with organic residues arranged in alleys in an agroforestry system, with and without use of fire, in the Caatinga biome, in Brazil. The experiment was conducted in a split-plot arrangement with four replications, with the factor fire in the plots, and the factor organic residues in the subplots. The organic residues used consisted of Gliricidia sepium plants; G. sepium plants and carnauba processing residue; G. sepium plants and bio-compost; and G. sepium plants, carnauba processing residue, and bio-compost, which were evaluated in three soil layers. The alleys with carnauba processing residue, G. sepium plants, and bio-compost presented a better maintenance of particulate, and mineral-associated organic carbon contents. Thus, the agroforestry management in alleys using these three residues was efficient for the maintenance of labile and recalcitrant organic matter compartments. Particulate organic carbon was more sensitive to changes in soil management than total organic matter content, in all alleys, presenting higher sensitivity indexes.

“…The secondary vegetation presented the highest values for the sustainability indicators of crop health and soil quality, which highlights the importance of ensuring this type of environment be maintained to ensure conservation of the biodiversity and of ecological processes; Silva et al (2020), avaliando a qualidade do solo em diferentes sistemas de produção utilizando indicadores visuais, verificaram que o manejo dos consórcios foi semelhante ao roçado agroecológico, com presença de árvores nativas, manejo da copa e permanência da serapilheira no solo, contribuindo na melhoria das características físicas e químicas do solo. Sendo justificado pelo manejo realizado pelos agricultores, tentando minimizar os impactos oriundos dos cultivos agrícolas, através de práticas conservacionistas, que possibilitaram a manutenção e conservação das propriedades do solo.…”

“…Com relação a diversidade de espécies dos sistemas agroflorestais, contribuiu, de forma significativa, para a melhoria da qualidade do solo, quando comparados aos sistemas sob monocultivo. Silva et al (2020), evaluating soil quality under different production systems using visual indicators, found that a management of intercropping was similar to the agroecological clearing of the land, where the presence of native trees, management of the crown, and permanence of the litter on the ground helped to improve the physical and chemical characteristics of the soil, and where the management carried out by farmers in trying to minimise the impacts caused by agricultural crops, included conservationist practices that made it possible to maintain and conserve the properties of the soil. Sousa et al (2018) found that intercropping can result in greater biological balance in the production system, since, as it presents greater crop diversity in any one area, it offers shelter and alternative food to the natural enemies of insects, pests and phytopathogens.…”

The aim of this article was to evaluate, using sustainability indicators, agroforestry systems (AFS) on the properties of family farmers in the district of Tomé-Açu, Pará, arising from the transition processes of different production systems. Eight AFS, three areas of secondary vegetation, and three conventional systems were evaluated. Direct observation was used to evaluate the sustainability indicators, assigning a value from 1 to 10 to each indicator (1 - undesirable; 5 - moderate and 10 - ideal). The mean value of the indicators was determined for each system under evaluation. The areas under conventional systems had the lowest value, of 0.25 for the crop-health indicators and 1.32 for soil quality, which suggests the need for proper management to prevent environmental problems in areas of pasture, cleared land and monocropped black pepper. The highest values of 4.1 for the crop-health indicators and 6.99 for soil quality, were obtained in the areas of secondary vegetation, and values of 3.0 for crop health and 6.1 for soil quality in the areas of AFS-BP, emphasising the role of secondary vegetation and agroforestry systems in recovering the productive potential of agrosystems. It can be concluded that the use of a simple technique (radar charts) together with statistical methods show that secondary vegetation, agroforestry and conventional systems differ; however, secondary vegetation and AFS are more sustainable, as they showed better results for each of the indicators under evaluation compared to the conventional systems.

“…Segundo Longo, Espindola e Ribeiro (1999) ao se considerar a atenuação devido às modificações antrópicas no meio, deve-se observar a estreita relação entre o solo e a vegetação (Costa et al, 2020). Além disso, deve-se utilizar-se de indicadores de qualidade, seja do solo ou da própria vegetação, a fim de se avaliar os mecanismos formados a partir da implantação desses sistemas de recuperação (Silva et al, 2020;Silva et al, 2021, Araujo et al, 2019 Objetivou-se com este trabalho quantificar os nutrientes no solo sob duas espécies de leguminosas (M. velloziana e T. candida) e em área com Floresta de Tabuleiros, e estimar o balanço de nutrientes no sistema solo-planta na área com as leguminosas.…”

As espécies leguminosas por suas características de alta deposição de serapilheira e fixação biológica de nitrogênio têm apresentado papel de destaque para a inserção em ambientes degradados. quantificar os nutrientes no solo sob duas espécies de leguminosas (Mimosa velloziana Mart e Tephrosia candida DC) e em área com Floresta de Tabuleiros, e estimar o balanço de nutrientes no sistema solo-planta na área com as leguminosas. Coletou-se amostras deformadas e indeformadas do solo nas profundidades de 0 – 5, 5 – 15 e 15 – 30 cm, procedendo-se as análises químicas. Verificou-se que os maiores teores de nutrientes estão contidos na camada superficial do solo. O solo sob a Floresta de Tabuleiros apresentou-se mais pobre nutricionalmente que o solo das leguminosas, apresentando, porém, maiores teores de matéria orgânica e nitrogênio total no solo. As leguminosas equipararam-se quanto a fertilidade do solo e ao balanço de nutrientes em seu local de inserção.Palavras-chave: Qualidade do solo; Reserva Natural Vale; Floresta de Tabuleiros, Mimosa velloziana Mart; Tephrosia candida DCNutrient balance in the system with leguminousABSTRACTLeguminous species, due to their characteristics of high litter deposition and biological nitrogen fixation, play an important role in insertion in degraded environments. quantify nutrients in the soil under two legume species (Mimosa velloziana Mart and Tephrosia candida DC) and in the area with native forest, and estimate the balance of nutrients in the soil-plant system in the area with legumes. We collected deformed and deformed samples at depths of 0 - 5, 5 - 15 and 15 - 30 cm, proceeding with chemical analysis. It was found that the highest levels of nutrients are contained in the topsoil. The soil under the native forest is found to be poorer than the leguminous soil, presenting, however, higher levels of organic matter and total nitrogen in the soil. As legumes, they were compared in terms of soil fertility and the balance of nutrients at their insertion site.Key words: Soil quality; Vale Nature Reserve; Tray Forest; Mimosa velloziana Mart; Tephrosia candida DC
