Soil total nitrogen (STN) plays an important role in plant growth, and rapid nondestructive detection of STN content is essential for agricultural production. Near-infrared spectroscopy (NIRS) takes advantage the fast speed, low cost, nondestructiveness, it can be used detection. Typically, NIRS-based approaches require a large number samples model training. However, difficult to collect sufficient due various causes (e.g., time-varying state, high assay costs, etc.) practical application. To tackle this problem, feature metric approach introduced detect based on NIRS work, new (named Pair-Soil-Spectra) proposed mine fine-grained features by contrasting different soil sample pairs, which full particle heterogeneity penetration. For validation study, three datasets with collection sources are selected as research subjects, performance Pair-Soil-Spectra analyzed from perspectives. According results, has significantly improved models partial least-squares (PLS), Cubist, extreme learning machine (ELM), random forest (RF)) small cases. Of these, coefficient determination RF 0.13, 0.42, 0.10, root-mean-square prediction decreased 0.15, 0.52, 0.01 g/kg datasets, gained greatest improvement. Meanwhile, easily expanded cover other domains.

Microbial traits are critical for carbon sequestration and degradation in terrestrial ecosystems. Yet, our understanding of the relationship between metabolic strategies genomic like genome size remains limited. To address this knowledge gap, we conducted a global-scale meta-analysis 2650 genomes, integrated whole-genome sequencing data, performed continental-scale metagenomic field study. We found that was tightly associated with an increase ratio genes encoding polysaccharide decomposition biomass synthesis defined as acquisition-to-biomass yield (A/Y). also show horizontal gene transfer played major evolutionary role expanded bacterial capacities acquisition. Our study further revealed significantly negative A/Y soil organic stocks. work demonstrates global encoded bacteria across microbiomes.

The soil microbial community influences and maintains quality health. Leguminous plants are widely used in forestry due to their nitrogen-fixing ability, significantly improving quality. However, there few studies on the effects of woody legumes communities Here, composition structure bulk associated with six cultivars Falcataria falcata (L.) Greuter & R. Rankin were analyzed using full-length 16S rRNA sequencing. Additionally, minimum dataset approach was employed integrate indexes physicochemical properties, allowing calculation a index evaluate cultivars’ Although growth characteristics identical, significant differences physiological functions. Notably, cultivar 6 demonstrated advantage over other its overall characteristics. Compared control sample, all clearly improved quality, 8 16 outperforming others. findings indicate that different improve fertility by recruiting microorganisms specific stability is crucial biological ecological factor sustains health key for evaluation these properties.

Microbiome research is becoming a mature field with wealth of data amassed from diverse ecosystems, yet the ability to fully leverage multi-omics for reuse remains challenging. To provide view into researchers' behavior and attitudes towards reuse, we surveyed over 700 microbiome researchers evaluate sharing challenges. We found that many are impeded by difficulties metadata records, challenges processing bioinformatics, problems repository submissions. also explored cost constraints at each step process better understand "pain points" more quantitative perspective sixteen active researchers. The bioinformatics was estimated be most time consuming, which aligns some frequently reported community survey. From these two approaches, present evidence-based recommendations how address concrete actions future work.
