Article Synopsis
- - Intensive farming strategies, particularly ecological intensification (EI) and organic management, are more sustainable than conventional management (CO) as they improve soil quality while maintaining high productivity levels.
- - The study revealed that EI leads to greater soil fertility and biodiversity, evidenced by higher numbers of beneficial bacterial taxa compared to CO, which mainly relies on inorganic fertilizers and often degrades soil health.
- - Different bacterial communities were linked to each management type, with CO support genera related to nitrogen and phosphorus cycles, whereas EI promoted bacteria that enhance organic matter breakdown and nutrient cycling, ultimately benefiting soil health.
Article Synopsis
- Restoration of mining sites in arid zones can be enhanced by using organic amendments, which help establish technosols and support ecosystem services.
- A 30-month study found that compost gardening and stabilized sewage sludge improved soil health, increased organic carbon and nitrogen, and led to significant changes in bacterial community structure.
- Notable differences in soil properties and bacterial diversity were identified, indicating that specific organic amendments play crucial roles in enhancing soil health and preserving biodiversity.
The composition and functioning of soil bacterial communities, as well as their responses to multiple perturbations, are not well understood in the terrestrial ecosystems. Our study focuses on the bacterial community of erosive and poorly developed soils (Haplic Leptosols) in Mediterranean rangelands of Extremadura (W Spain) with different grazing intensities. Leptosols from similar natural conditions were selected and sampled at two depths to determine the soil properties as well as the structure and activity of bacterial communities.

Despite an extensive body of literature exploring the effects of grazing on soil and plants worldwide, there is a notable lack of research on its impacts in Mediterranean forests within the Iberian Peninsula Furthermore, there is a knowledge gap on the enzymatic activities and basal respiration of soil in forest after grazing. To address these gaps, this study aimed to investigate the impact of grazing on various important physicochemical and biological soil properties along with vegetation richness in a Mediterranean forest located in Castilla-La Mancha (Central Eastern Spain).

This study evaluate the effects of four organic soil amendments on soil. Physical, chemical and biochemical properties were compared to untreated and natural (not cultivated) soils in a semiarid region (Andalusia, Spain). A large set of physical, chemical biochemical properties and, the composition of bacterial communities; and overall soil quality index (SQI) were evaluated on soils treated with organic soil amendments of animal origin (compost from sheep and cow manure [CS] or chicken manure, [CK], vegetal origin (greenhouse crop residues [CC]), and vermicompost (CV).
