“…On the other hand, the literature suggests that rhizosphere microorganisms might play an important role in driving and regulating the activation of soil nitrogen (N) and phosphorus (P) (CAI et al, 2023). Although our study did not directly investigate this interaction, the species that appear to benefit from these conditions include Q. paraensis (Y1) and Sterigmapetalum obovatum Kuhlm.…”

The floristic composition of fragmented landscapes can significantly influence their potential resilience and regeneration in the event of natural or anthropogenic disturbance. This study aimed to characterize soil influence on tree composition and determine the relationship of edaphic variables to the predominant species in a part of the Amazon Forest under selective logging. The fixed area method was applied to clusters of 10 × 250 m, considering trees with a DBH ≥ 10 cm. The 20 highest-importance species of the fragment composed the vegetation matrix. For the characterization of the forest soil, three soil samples composed of subunits were collected, and the edaphic variables were represented by pH H2O, pH CaCl2, P, K, Ca, Ca+Mg, Mg, Al, H, OM, SB, CEC, V%, Ca%, Mg% and TOC. Despite the low tree density found in the study, the high basal area suggests that the species present are tolerant to changes and environmental disturbances. The tree component is dominated by species characteristic of degraded environments, where the soil’s chemical composition explains most of the species variation. Qualea paraensis, Bellucia grossularioides, Cheiloclinium cognatum, Diplotropis purpurea and Erisma uncinatum show great potential for use in degraded forest ecosystems in the Amazon Biome. Keywords: anthropic disruption; deforestation; ecological requirements; forest ecosystem recovery; tropical rainforest. Influência das variáveis edáficas na predominância de espécies florestais após exploração seletiva no bioma amazônico RESUMO: A composição florística de paisagens fragmentadas pode influenciar significativamente o seu potencial de resiliência e regeneração em caso de perturbação natural ou antropogénica. O objetivo deste trabalho foi caracterizar a influencia do solo na composição arbórea e determinar a relação das variáveis edáficas com as espécies predominantes em uma parte da Floresta Amazônica sob exploração madeireira seletiva. O método de área fixa foi aplicado para aglomerados de 10 X 250 m, considerando arvores com DAP ≥ 10 cm. As 20 espécies de maior importância do fragmento compuseram a matriz vegetal. Para a caracterização do solo florestal foram coletadas três amostras de solo compostas por subunidades e as variáveis edáficas foram representadas por pHH2O, pHCaCl2, P, K, Ca, Ca+Mg, Mg, Al, H, OM, SB, CEC, V%, Ca%, Mg%, e TOC. Apesar da baixa densidade arbórea encontrada no estudo, a elevada área basal sugere que as espécies presentes são tolerantes a mudanças e pertubações ambientais. O componente arbóreo é dominado por espécies características de ambientes degradados, onde a composição química do solo explica a maior parte da variação das espécies. As espécies Qualea paraensis, Bellucia grossularioides, Cheiloclinium cognatum, Diplotropis purpurea e Erisma uncinatum apresentam grande potencial para utilização em ecossistemas florestais degradados na Amazónia. Palavras-chave: perturbação antrópica; desmatamento; requerimentos ecológicos; recuperação do ecossistema florestal; floresta tropical.

“…In this study, organic matter content contributed 25% of the soil quality index. Soil biology is an excellent indication of soil quality and health since soil organic matter content impacts nutrient reserve, soil structure, infiltration rate, water retention capacity, and numerous soil ecological functions (Ngangom et al, 2020;Cai et al, 2022;Hassan et al, 2022). In tropical ecosystems, soil fertility is also an important quality component that impacts soil productivity as well as controlling soil biological, chemical, and physical features (Schiefer et al, 2015;Erkossa et al, 2018).…”

Several studies have assessed the dynamics of soil quality induced by soil and water conservation (SWC), but many showed disagreement over the efficacy of SWC interventions in the Ethiopian highlands. This study used a before and after soil and water conservation practices (SWCP) comparison approach to evaluate the effect of SWCP on soil quality dynamics. Fifty-four composite and 10 undisturbed soil samples were collected in 2012 (before SWCP) and 2022 (after SWCP). Statistical mean, analysis of variance, and principal component analysis were applied to test the significant differences among treatments. The findings demonstrated that SWCP has significantly improved most of the soil quality indicators such as soil organic matter, total nitrogen, available phosphorous, pH, total porosity, field capacity, and available water, and reduced the value of bulk density and coarse fragments. The interaction effect of landscape position and types of structures provided statistically significant results for soil organic matter, total nitrogen, magnesium, calcium, and base saturation. Soil and stone-faced soil bunds treated at lower landscapes were superior in improving soil quality attributes. The soil quality indexing showed, the overall soil quality improvement as a result of SWCP was about 32.15%. The level of improvement for different SWCPs was 32% for stone faced soil bunds and 33% for soil bunds. The findings revealed that SWCP implementation can improve soil quality. Soil organic matter is a key biological quality component that contributed 25% to the soil quality index and highly impacted soil physicochemical properties. We suggest additional assessment of best and integrated land management practices to ensure further improvement in soil quality, crop productivity, and ecosystem services in the subhumid ecosystems.
