The practical recommendation for the single application rate of compost in terms of the microbial community functioning for carbon retention still needs to be specified. It could be both economically and ecologically viable. The study combines two trials to ascertain: (1) short-term dynamics in indices of C retention (organic and microbial carbon content) and loss (basal respiration and soil respiration in situ) after a single application of compost to Albic Retisols at low and high (30 and 70 Mg dry mass ha −1 , respectively) rates for 1.5 years in a field trial; (2) long-term effects of compost application rates from 10 to 100 Mg ha −1 on the retention of a stable C pool considering two climate change scenarios (SSP2-4.5 and SSP5-8.5) using the DeNitrification–DeComposition model. The short-term trial revealed that the low application rate of compost was more effective due to higher soil capacity to assimilate C into microbial biomass in relation to C loss under conditions of accelerated organic matter decomposition. The long-term modeling trial demonstrated that a stable pool of C can be maintained for two decades following a single application of compost at a rate of at least 30 Mg ha −1 . The results suggest that the single application of compost at rates of 30 Mg ha −1 shows promise for the retention of C in the stable pool over a period of at least two decades for Albic Retisols under the milder rate of climate change.","在农业中使用堆肥有利于废物管理和土壤健康。关于以微生物群落功能维持碳固持为目标的堆肥单次施用量的实用推荐值，仍有待明确。这一推荐值可能在经济和生态两方面均具有可行性。本研究结合了两项试验以确定：(1)在田间试验中，向漂白淋溶土（Albic Retisols）单次施用低量和高量堆肥（分别为30和70 Mg干质量 ha⁻¹）后1.5年内，碳固持指标（有机碳和微生物碳含量）与碳损失指标（基础呼吸和原位土壤呼吸）的短期动态；(2)利用反硝化-分解（DeNitrification–DeComposition）模型，在两种气候变化情景（SSP2-4.5和SSP5-8.5）下，评估10至100 Mg ha⁻¹堆肥施用量对稳定碳库固持的长期影响。短期试验表明，低施用量堆肥更为有效，因为在有机质加速分解的条件下，土壤将碳同化至微生物生物量的能力相对于碳损失更高。长期模拟试验表明，单次施用堆肥至少30 Mg ha⁻¹后，稳定碳库可维持二十年。结果表明，在气候变化较为温和的情景下，对于漂白淋溶土，单次施用30 Mg ha⁻¹的堆肥有望在至少二十年内将碳固持于稳定碳库中。",null,"Frontiers in Sustainable Food Systems","2026-09-17T00:00:00Z","论文",10,false,75,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},12,22,18,13,1,"田间试验与DNDC模型结合，给出堆肥单次施用30 Mg\u002Fha可维持稳定碳库至少二十年的量化结论，对有机肥固碳实践有参考价值，但属细分领域研究，公共影响有限。",[24],{"name":10,"url":6},[26,27,28,29,30],"气候变化","模型模拟","有机肥","农业减排","土壤固碳",0,"10.3389\u002Ffsufs.2026.1945623",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":6,"card":60,"direction":64,"ingested_from":66},"W7213473225",[36,38,40,42,44,46,48,50,53,55,58],{"name":37,"orcid":9},"Kristina Ivashchenko",{"name":39,"orcid":9},"Aleksei Dobrokhotov",{"name":41,"orcid":9},"Dmitry Khoroshaev",{"name":43,"orcid":9},"Софья ЖЕЛЕЗОВА",{"name":45,"orcid":9},"Sofia Sushko",{"name":47,"orcid":9},"Dmitry Sokolov",{"name":49,"orcid":9},"Timur Zhuk",{"name":51,"orcid":52},"Nadezhda Ananyeva","https:\u002F\u002Forcid.org\u002F0000-0002-0434-6071",{"name":54,"orcid":9},"Mikhail Sevostyanov",{"name":56,"orcid":57},"Д В Демин","https:\u002F\u002Forcid.org\u002F0000-0002-0469-7015",{"name":59,"orcid":9},"Olga Gavrichkova",{"tldr":61,"method":62,"finding":63,"direction":64,"opportunity":65},"结合田间试验与模型模拟，确定单次施用堆肥对白化网纹土有机碳保持的最佳用量。","田间1.5年试验与DNDC模型模拟两种气候情景下10-100 Mg\u002Fha堆肥效果","低施用量短期固碳效率更高，至少30 Mg\u002Fha可维持稳定碳库二十年。","农业绿色发展与碳","可探索不同土壤类型和气候情景下堆肥单次施用的长期固碳阈值与微生物机制。","openalex","2026-09-17T23:30:07.790294Z"]
