Soil oxidative enzyme activities, including catalase, lignin peroxidase, manganese peroxidase, and laccase, were also enhanced by compost addition. Bacterial diversity was highest under low-rate bio-compost, whereas fungal diversity and trophic strategies showed stronger responses to fertilization. Principal coordinate analysis and permutational multivariate analysis of variance indicated that both bacterial and fungal community compositions were significantly altered by 30 years of compost application. The bacterial oligotroph\/copiotroph ratio remained relatively stable among treatments, while the fungal oligotroph\/copiotroph ratio decreased significantly under low-rate bio-compost. Specifically, this treatment significantly decreased the relative abundance of the oligotrophic fungal phylum Basidiomycota while increasing the copiotrophic phylum Ascomycota, indicating a shift toward copiotrophic fungal groups. Co-occurrence network analysis showed that the high-rate bio-compost significantly enhanced microbial network complexity, increasing the number of nodes from 419 (control) to 753 and edges from 828 to 1841 in the bacterial network, suggesting enhanced microbial connectivity under high-rate bio-compost application. Correlation, Mantel, and redundancy analyses further identified soil total phosphorus and oxidative enzyme activities, especially manganese peroxidase, lignin peroxidase, and laccase, as key factors associated with microbial community variation and trophic group distribution.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Overall, long-term bio-compost application improved soil fertility, stimulated oxidative enzyme activities, enhanced microbial network complexity, and regulated microbial life-history strategies, with different responses between bacterial and fungal communities.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmicb.2026.1910948","type":"journal-article","created":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T06:00:18Z","timestamp":1790748018000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of long-term application of traditional compost and bio-compost on soil microbial community structure and life-history strategies"],"prefix":"10.3389","volume":"17","author":[{"given":"Lizhan","family":"Liu","sequence":"first","affiliation":[{"name":"Technical Centre for Soil, Agriculture and Rural Ecology and Environment, Ministry of Ecology and Environment","place":["Beijing, China"]},{"name":"School of Biological Sciences and Technology, Beijing Forestry University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Biological Sciences and Technology, Beijing Forestry University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofang","family":"Wu","sequence":"additional","affiliation":[{"name":"Technical Centre for Soil, Agriculture and Rural Ecology and Environment, Ministry of Ecology and Environment","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Fan","sequence":"additional","affiliation":[{"name":"College of Resources and Environmental Sciences, China Agricultural University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peipei","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Biological Sciences and Technology, Beijing Forestry University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Li","sequence":"additional","affiliation":[{"name":"Technical Centre for Soil, Agriculture and Rural Ecology and Environment, Ministry of Ecology and Environment","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenbing","family":"Tan","sequence":"additional","affiliation":[{"name":"State Environmental Protection Key Laboratory of Simulation and Control of Groundwater Pollution, Chinese Research Academy of Environmental Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiawei","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Biological Sciences and Technology, Beijing Forestry University","place":["Beijing, China"]},{"name":"Institute of Tree Development and Genome Editing, Beijing Forestry University","place":["Beijing, China"]},{"name":"Beijing Key Laboratory of Food Processing and Safety in Forestry, Beijing Forestry University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,30]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"2973","DOI":"10.3390\/agronomy14122973","article-title":"Influence of effective microbial additives inoculation on indigenous bacterial community dynamics and co-occurrence patterns during the composting of mixed food waste and livestock manure","volume":"14","author":"Bang","year":"2024","journal-title":"Agronomy"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"104450","DOI":"10.1016\/j.apsoil.2022.104450","article-title":"A meta-analysis of the effect of organic and mineral fertilizers on soil microbial diversity","volume":"175","author":"Bebber","year":"2022","journal-title":"Appl.
