Sustainable soil health management is pivotal for advancing agricultural productivity and ensuring global food security. This review comprehensively evaluates the effects of mineral-organic fertilizer ratios on microbial communities, enzymatic dynamics, functional gene abundance, holistic health. By integrating bioinformatics, enzyme activity assays, metagenomic analyses, we demonstrate that balanced fertilization significantly enhances diversity, community stability, resilience against environmental stressors. Specifically, synergistic application mineral organic fertilizers elevates β-glucosidase urease activities, accelerating matter decomposition nutrient cycling while modulating taxa critical transformation pathogen suppression. Notably, replacing 20-40% with alternatives mitigates risks such as greenhouse gas emissions leaching sustaining crop yields. dual approach improves structure, boosts water retention capacity, increases biomass by 20-30%, fostering long-term fertility. Field trials reveal yield 25-40% in crops like rice maize under combined fertilization, alongside enhanced carbon (110.6%) nitrogen content (59.2%). The findings underscore necessity adopting region-specific, strategies to optimize ecological sustainability productivity. Future research should prioritize refining frameworks through interdisciplinary approaches, addressing soil-crop-climate interactions, scaling these practices diverse agroecosystems. aligning policies principles, stakeholders can safeguard health-a cornerstone human wellbeing-while securing resilient systems future generations.

Energy supply on high mountains remains an open issue since grid connection is not feasible. In the past, diesel generators with lead–acid battery energy storage systems (ESSs) were applied in most cases. Recently, photovoltaic (PV) lithium-ion (Li-ion) ESSs have become suitable for solving this problem a greener way. 2016, off-grid PV system Li-ion ESS was installed Paiyun Lodge Mt. Jade (the highest lodge Taiwan). After operating more than 7 years, aging of whole electric power became critical its long-term usage. work, method established analyzing massive data (over million rows), such as daily operation patterns, well C-rate, temperature, and accumulated distributions, estimating health system. A completed improvement project dealing reported. Based usage experience, simple cost analysis model comparing built, revealing that expensive batteries can compete cheap mountains.
