Metagenomic analysis was further performed to evaluate the remediation efficacy of PGPR. The results demonstrated that PGPR application significantly increased soil pH and nutrient levels (e.g., organic carbon, available nitrogen, phosphorus, and potassium) and enhanced soil enzyme activities, including protease, urease, acid phosphatase. PGPR inoculation also restored microbial diversity, optimized community structure, and upregulated functional genes associated with carbon, nitrogen, and phosphorus cycling. Moreover, tea leaf quality was improved, as evidenced by an increase in amino acid content and a reduction in phenol-ammonia ratio. Overall, the introduction of PGPR effectively mitigated the adverse impacts of glyphosate, thereby improving soil health and tea quality.

In this study, we evaluated how soil biodiversity influences primary production, ecosystem stability, nutrient cycling, and soil fertility across three land uses (natural ecosystem, pasture, and deforested area) and two seasons (rainy and dry), using a 3 × 2 randomized block design replicated over three years. Soil biodiversity was characterized through the abundance and diversity of insects, arachnids, myriapods, nematodes, arbuscular mycorrhizal fungi, macroscopic fungi, and microbial gene diversity. Pearson’s correlation analysis showed strong positive relationships between soil biodiversity and primary production (r = 0.97), ecosystem stability (r = 0.98), and nutrient cycling (r = 0.82). The multifunctionality index was up to 2.4 times higher in natural ecosystems compared to deforested sites. Deforestation led to an 88 % reduction in plant richness, replacing native species with disturbance-tolerant taxa such as <em>Cenchrus echinatus</em> and <em>Mimosa hostilis</em>.

Sites, with high environmental variation between them, were selected in mature, cleared and naturally recovering <em>Eucalyptus grandis</em> blocks located in the Western Cape, South Africa.

Compared to the standard wheat bran bait, the nettle bait presented the lowest estimates of feeding activity across all sites, while the jelly bait showed similar levels of soil feeding activity within each block. Therefore, the nettle bait cannot be recommended as a bait material, while the jelly bait could serve as an adequate proxy for the wheat bran bait. These results are particularly important for small-scale studies, such as the present study, to obtain snapshots of potential bait preferences.

We sampled 72 sites (27 arable fields, 27 field margins, and 18 grasslands) in eastern Austria; earthworms were assessed by hand sorting, microarthropods by Berlese extraction.
