“…Silva et al (2022) found that areas with natural vegetation present approximately 28% lower soil temperature when compared to areas with little plant cover, and that environmental stimuli, such as temperature and soil moisture, affect the organic matter decomposition dynamics and, consequently, the release of soil CO 2 , indicating that management techniques that reduce the soil surface temperature and increase organic matter contents should be prioritized to improve soil biota. These attributes emerge as important indicators of soil environmental quality, as they estimate the extent of functional sustainability regarding ecological aspects of land use and occupation systems (SILVA et al, 2021).…”

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.

“…The present findings provide crucial information for research on the management and conservation of tropical soils and may allow us to infer that the forms of land use and occupation induce changes in the quality of the soil environment, which may have repercussions on the establishment of populations or communities and their processes (J. H. C. S. Silva et al, 2021). This knowledge can stimulate the use of management techniques to support the recovery of modified areas and the insertion of more sustainable production systems, aiming at mitigating global warming.…”

“…The increasing soil degradation has promoted the adoption of agricultural management techniques that combine agricultural production with conservation of the soil environment (J. H. C. S. Silva et al, 2021). In this respect, systems that integrate natural vegetation and ecosystems transformed by humans are efficient for the production of goods and services, besides acting as a potential carbon sink for the atmosphere by storing a greater amount of carbon in the soil (Nogueira et al, 2020).…”

Deforestation and the disorderly exploitation of natural resources for agricultural expansion occurred at an accelerated pace in the Brejo microregion of the state of Paraíba, Brazil, which resulted in abandonment and erosion of the soil in a large part of the region. In view of this scenario, the present study was undertaken to investigate the soil respiration in systems involving different forms of land use and cover in caatinga enclaves moist forests (Brejo de Altitude areas). The study was conducted in four land use and cover systems, namely, pasture, mandala agriculture, agroforestry system, and forest. Microbial activity was estimated by quantifying the carbon dioxide (CO2) released in the soil respiration process, from the soil surface, and captured by KOH solution. Soil temperature (°C) and water content (%) were monitored simultaneously with the analysis of soil respiration. The forms of land use and cover have a direct effect on the metabolic activity of soil organisms, and climatic factors such as soil temperature and moisture influence the dynamics of organic matter decomposition and, consequently, the release of CO2. The production of CO2 is higher at night than during the day, regardless of the analyzed systems. Among the evaluated areas, the forest showed the lowest CO2 emissions, so it was considered a CO2 receptor in contrast to the pasture area, which functioned as a CO2 emitter. Management techniques that reduce surface temperature and increase organic matter should be prioritized to promote soil biota.

“…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
