Establishing perennial cultivated grasslands on the Qinghai-Tibet Plateau helps address seasonal imbalance of forage resources and supports restoration degraded grasslands. The most common planting patterns-monocropping mixed cropping-are well-studied in terms vegetation structure, productivity, soil nutrients. Despite their significance, influence prolonged practices underground microbial communities metabolites has often been neglected. In this study, two characteristic plants, Festuca sinensis 'Qinghai' Poa pratensis 'Qinghai', from area around Qinghai Lake were selected as experimental subjects by employing 16 S ITS sequencing methods conjunction with non-targeted metabolomics analysis. effects patterns (monocropping cropping) rhizosphere characteristics, community structure examined. results showed that compared monocropping, cropping significantly increased contents nutrients key metabolites. addition, it had a greater impact fungal diversity than bacterial diversity, particularly β-diversity. While α-diversity dominant phyla remained stable, fungi more responsive to changes properties These show new niche differentiation between different species grassland stimulates secretion trehalose valine, which further affects enhances ecological functions findings will guide selection strategies improve local sustainable productivity.

Rhizosphere microbes play critical roles for plant's growth and health. Among them, the beneficial rhizobacteria have potential to be developed as biofertilizer or bioinoculants sustaining agricultural development. The efficient rhizosphere colonization of these is a prerequisite exerting their plant functions, but colonizing process underlying mechanisms not been thoroughly reviewed, especially nonsymbiotic rhizobacteria. This review systematically analyzed root compared it with that symbiotic pathogenic bacteria. also highlighted approaches improve efficiency proposed study rhizobacterial from holistic perspective microbiome under more natural conditions.

Plants can produce and release allelochemicals to interfere with the establishment growth of conspecific interspecific plants. Such allelopathy is an important mediator among plant species in natural managed ecosystems. This review focuses on grasslands forests. Allelopathy drives invasion, exacerbates grassland degradation contributes forest regeneration. Furthermore, autotoxicity (intraspecific allelopathy) frequently occurs pastures tree plantations. Various specialized metabolites, including phenolics, terpenoids nitrogen-containing compounds from herbaceous woody are responsible for Terpenoids a diversity metabolites qualitative occurring annual grasslands, while phenolics few quantitative perennial Importantly, mediate below-ground ecological interactions plant–soil feedback, subsequently affecting biodiversity, productivity sustainability Interestingly, allelopathic plants discriminate identity neighbors via signaling chemicals, adjusting production allelochemicals. Therefore, chemicals synergistically interact regulate intraspecific forests have provided fascinating insights into plant–plant their consequences sustainability, contributing our understanding terrestrial ecosystems global changes.

Plant–soil feedback (PSF) was initially developed in the field of agricultural practices. In recent years, PSF has been extended to various ecosystems. Root exudates, essential for exchange materials, energy, and information at plant–soil interface, significantly influence PSF. However, how is driven by root secretions role these different pathways still needs be further explored, particularly forest Soil nutrients, microbial communities, nematodes are important research topics process exudates. Investigating aspects exudates provides valuable insights into complex interactions both above ground below surface. This can offer theoretical support guidance building stable, healthy, sustainable ecosystems future.

Maintaining soil health is fundamental to sustaining agricultural productivity, however, the intricate role of microbial diversity in this process not fully understood. Current research acknowledges that microorganisms including bacteria, fungi, and archaea are pivotal driving essential functions such as nutrient cycling, organic matter decomposition, disease suppression. However, impacts global environmental changes intensive practices on these remain a critical gap literature. This significant because decline could severely compromise health, consequently crop productivity. Here, we provide comprehensive review factors influencing examine their implications for performance. We assess both natural pH, moisture, temperature, vegetation type well human-induced tillage systems fertilizer application.

Contamination of heavy metal(loid) in soils is a global problem. Various remediation technologies have thus been applied to mitigate the ecological and health risk metal(loid)s contaminated soils. Majority review studies mainly focus on mobility or accumulation metal(loid)s, but little attention has paid alteration soil fertility (e.g. nutrient, structure enzyme activities) which are most closely related plant growth during process. Here, we summarized influence physical, chemical biological fertility, they indicated that: (1) thermal treatment washing usually decreased nutrients activities, as well deteriorated structure; (2) improved microorganism decrease through nutrient uptake by plants cannot be ignored; (3) amendments displayed various depended their properties; (4) combination multiple could neutralize negative single technology fertility. In future, both toxicity improve more recommended.
