“…We have used the Bonferroni's test as the post hoc test ( p < 0.05) to compare the mean values between the studied habitats. We performed a nonmetric multidimensional scaling (NMDS) to analyze differences between the studied sites in terms of the abundance of AMF species using the “metaMDS” function with Bray–Curtis’ matrix as described by da Silva et al [28]. A structural equation model (SEM) was performed to explore the direct effect of C. madagascariensis on AMF abundance and diversity and the indirect effects via changes in soil biochemical properties.…”

Invasive alien plant species (IAPS) have the ability to change the biochemical properties and the arbuscular mycorrhizal fungal (AMF) community structure in their rhizosphere. Organic acids, microbial activity, and AMF play a key role in the invader's spread and also has interactions with the soil chemical factors. Our aim here was to assess the rhizosphere's biochemical factors, AMF community composition, and soil chemical properties associated with Cryptostegia madagascariensis (IAPS) and Mimosa tenuiflora (endemic plant species) from the Brazilian Seasonal Dry Forest. The highest values of total glomalin (5.87 mg g−1 soil), root colonization (54.5%), oxalic and malic acids (84.21 and 3.01 μmol g−1, respectively), microbial biomass C (mg kg−1), Na+ (0.080 cmolc kg−1), Ca2+ (7.04 cmolc kg−1), and soil organic carbon (4.59 g kg−1) were found in the rhizosphere of C. madagascariensis. We found dissimilarities on AMF community structure considering the studied plant species: (i) Racocetra coralloidea, Dentiscutata heterogama, Dentiscutata cerradensis, Gigaspora decipiens, and AMF's richness were highly correlated with the rhizosphere of M. tenuiflora; and (ii). The rhizosphere of C. madagascariensis was highly correlated with the abundance of Claroideoglomus etunicatum, Rhizoglomus aggregatum, Funneliformis mosseae, and Funneliformis geosporum. The results of our study highlight the importance of considering C. madagascariensis as potential hosts for AMF species from Glomerales, and a potential plant species that increase the bioavailability of exchangeable Na and Ca at semi‐arid conditions.

“…To determine litter deposition, litter material was collected following a 30-day schedule from August 2021 to September 2022. We used three metallic squares (1 × 1 m) per plot on the soil surface [14], and the sampling points were randomly selected before sampling by using digital map and geographic coordinates. The litter material inside the metallic square was collected using plastic bags.…”

“…Throughout the experiment, Provid-type traps (each trap had four windows with a 4 cm × 4 cm opening) were placed using a 2-day schedule without any disruption to collect soil fauna specimens (e.g., we placed the traps 12 times following a 30-day schedule throughout the experiment), but we presented the mean in our results. In each trap, we added 200 mL of distilled water and neutral detergent solution at a concentration of 25% with 30 mL of 70% alcohol [14]. Soil fauna specimens (macrofauna-specimens longer than 0.2 cm and mesofauna-specimens shorter than 0.2 cm) were preserved in 70% alcohol and considered for our analyses.…”

“…Our aim here was to understand the effect of site quality level in the interaction among litter, soil-solid phase, and organism assemblage on A. angustifolia cultivated in subtropical Cambisol. To this end, we analyzed the soil chemical properties [13], litter properties [14], and soil organism abundance [15] for three site quality degrees. We hypothesized that the high-quality sites would present high litter deposition with a low lignin content and high macronutrient content (N, P, and K) and soil exchangeable cation content.…”

Different site quality levels in Araucaria angustifolia (Bert.) O. Kuntze plantations may influence the soil organisms and the interaction between litter and soil chemical properties by providing habitats and nutrients in different pathways. Our aim here was to understand the effect of site quality level in the interaction among litter, soil–solid phase, and organism assemblage on A. angustifolia, Campo Belo de Sul, Santa Catarina, Southern Brazil. In the low site quality, the litter deposition, litter K content, litter Ca content, soil organic matter, soil P content, soil K content, and soil exchangeable Ca reduced by 50.50, 49.54, 11.89, 20.51, 11.74, 61.18, and 35.18%, respectively, when compared to the high site quality. Nonmetric multidimensional scaling (NMDS) grouped the influence of site quality degree into three groups, considering the dissimilarities among soil organisms. The ordination of the soil organisms, richness, and Shannon’s diversity in each studied site quality degree had a stress value of 0.08. The structural equation models showed that the loss of site quality had a negative relationship with soil organism assemblage and soil and litter compartments. Our study highlights the fact that a fertile soil, a soil enriched in organisms, and enough litter support the forest productivity.

Background Cover crops and mulching can ameliorate soil porosity and nutrient availability, but their effects on the physical characteristics and nutrients in the raised bed soils are unclear. Methods The field experiment was conducted in a pomelo orchard from 2019 to 2021, with an area of 1,500 m2. The treatments included control (no cover crop), non-legume cover crop (Commelina communis L.), legume cover crop (Arachis pintoi Krabov & W.C. Gregory), and rice straw mulching (Oryza sativa L.). At the end of each year (2019, 2020, and 2021), soil samples were collected at four different layers (0–10, 10–20, 20–30, and 30–40 cm) in each treatment. Soil bulk density, soil porosity, and the concentration of nutrients in the soil were investigated. Results The results revealed that soil bulk density at two depths, 0–10 and 10–20 cm, was reduced by 0.07 and 0.08 g cm−3 by rice straw mulch and a leguminous cover crop, thus, increasing soil porosity by ~2.74% and ~3.01%, respectively. Soil nutrients (Ca, K, Fe, and Zn) at topsoil (0–10 cm) and subsoil (10–20 cm) layers were not significantly different in the first year, but those nutrients (Ca, K, Fe, and Zn) improved greatly in the second and third years. Conclusions Legume cover crops and straw mulch enhanced soil porosity and plant nutrient availability (Ca, K, Fe, and Zn). These conservation practices best benefit fruit orchards cultivated in the raised bed soils.
