Whether microbial inoculation can accelerate this process while producing a horticultural growing medium remains unclear. We compared coffee husks composted with a commercial microbial agent (a consortium of photosynthetic bacteria, lactic acid bacteria, yeast, filamentous fungi, and actinomycetes) (CHM) versus without (CH) over 180 days. The CHM treatment reached a higher peak temperature (55.6\u00a0\u00b0C vs. 43.5\u00a0\u00b0C) and at the end of composting achieved a numerically greater seed germination index (93.2% vs. 71.2%), indicating enhanced maturation and reduced phytotoxicity. High throughput sequencing showed that CHM did not drastically alter overall microbial \u03b1 diversity but the final compost exhibited a marked reduction in the relative abundance of the genus\n                    <jats:italic>Fusarium<\/jats:italic>\n                    compared to CH. Beneficial bacterial genera such as\n                    <jats:italic>Pseudomonas<\/jats:italic>\n                    ,\n                    <jats:italic>Sphingomonas<\/jats:italic>\n                    , and\n                    <jats:italic>Alcaligenes<\/jats:italic>\n                    showed a non-significant but consistent trend toward enrichment in CHM. When the mature CHM compost was blended with vermiculite, perlite, and decomposed cow manure, blends with lower compost inclusion (1:5 or 1:3 volume ratio of CHM compost to other components) supported tomato seedling growth comparable to a conventional peat based medium. These results demonstrate that microbial inoculation promote a more intense thermophilic phase and enhances final maturity in coffee husk composting, yielding a product with potential to partially substitute for peat in horticultural substrates. This approach offers a practical strategy for recycling coffee processing byproducts into a compost-based growing medium component.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2026.1906101","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T04:41:29Z","timestamp":1788928889000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Microbial inoculation enhanced the thermophilic phase and improved final maturity-related properties of coffee husk composting for tomato seedling substrate production"],"prefix":"10.3389","volume":"17","author":[{"given":"Fang","family":"Liu","sequence":"first","affiliation":[{"name":"School of Agriculture, Yunnan University","place":["Kunming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruixiang","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Agriculture, Yunnan University","place":["Kunming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"He","sequence":"additional","affiliation":[{"name":"School of Agriculture, Yunnan University","place":["Kunming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiwen","family":"Qin","sequence":"additional","affiliation":[{"name":"School of Agriculture, Yunnan University","place":["Kunming, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feifei","family":"He","sequence":"additional","affiliation":[{"name":"School of Agriculture, Yunnan University","place":["Kunming, China"]},{"name":"Yunnan Provincial Key Laboratory of Coffee","place":["Baoshan, Yunnan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"11","DOI":"10.1017\/s0021859600021572","article-title":"Determination of nitrogen in soil by the Kjeldahl method","volume":"55","author":"Bremner","year":"1960","journal-title":"J.
