有机质（OM）中保存的大量太阳能通量通过土壤作为从初级生产到矿化的管道。土壤（微生物）生物正在引导通量，由所提供的能量提供燃料，并通过其生物和坏死物质做出贡献。热力学原理一般适用于地球系统，因而也适用于土壤。因此，我们需要考虑与土壤中的碳使用、生物群落结构和环境边界条件相关的微生物组的能量使用和维持（能量预算）。作为SPP 2223的协调项目，SoilSystems将通过组织跨学科知识交流和合作，土壤和基质提供，数据收集和完善，综合和建模，为SPP的研究提供科学和组织框架。这是由一个协调小组在协调助理的支持下完成的，协调助理处理A）科学进展和B）SPP 2322的组织管理。A）土壤系统旨在通过将土壤视为能量驱动系统来扩大土壤研究，包括热力学概念。该项目将应用一个系统概念，将吉布斯能和产热变化的平衡与（i）OM周转（质量平衡、保留、途径、化学计量、动力学）和（ii）微生物组（活性、功能特征、营养相互作用）联系起来。SoilSystems将专注于碳和能量利用效率（CUE，埃厄）的微生物过程，这些微生物过程驱动OM沿着能量利用渠道，从而将易于降解的碎屑分子转化为微生物生物量，并最终长期稳定的坏死物质。这一概念将应用于一套合作的核心项目，使用土壤培养实验和同位素标记的基板与确定的能源供应和分子结构，以评估损失，效率，以及能源和物质的保留模式。它的目的是结合联合收割机热力学为基础的分析和概念建模与时间和空间分辨采样。SoilSystems将为理解陆地生态系统中的能量保持和元素循环迈出实质性的一步。因此，SoilSystems旨在回答关键问题：是什么驱动了土壤中以碳周转和储存为例的综合能量和物质通量-微生物组，能量输入，矿物和（环境）边界条件，或所有的相互作用？B）为了优化SPP 2322中的合作研究，所有参与项目都将受益于集中管理。将通过一个共同的实验平台提供土壤、基质和量热仪器。数据在一个联合数据储存库中储存和共享。通过促进外部合作和一名墨卡托研究员支持研究。项目会议邀请讨论和演示。并非最后一项具体措施将使两性平等能够充分参与研究和学术生涯

Large fluxes of solar energy conserved in organic matter (OM) pass through soil as conduit from primary production to mineralisation. Soil (micro)organisms are channelling the flux, are fuelled by the provided energy, and contribute by their bio- and necromass. Thermodynamic principles are generally valid for the Earth System, and thus also for soils. Hence, we need to consider the energy use and maintenance (energy budgets) of microbiomes related to carbon use, biocoenotic structures and environmental boundary conditions in soil. SoilSystems as the coordination project of SPP 2223 will provide the scientific and organisational framework for conducting research in the SPP by organizing interdisciplinary knowledge exchange and collaboration, soil and substrate provision, data collection and refinement, synthesis and modelling. This is done by a coordination panel supported by a coordination assistant dealing with A) the scientific progress and B) the organizational management of SPP 2322.A) SoilSystems aims to widen soil research by considering soils as energy driven systems by including thermodynamics concepts. The project will apply a systemic concept for linking balances of changes of Gibbs energy and heat production to (i) OM turnover (mass balances, retention, pathways, stoichiometry, kinetics) and (ii) to the microbiome (activity, functional traits, trophic interactions). SoilSystems will focus on poorly understood microbial processes of carbon and energy use efficiency (CUE, EUE) that drive OM along energy use channels, thereby converting easily degradable detritus molecules to microbial biomass and finally long-term stabilised necromass. This concept will be applied in a set of collaborative core-projects using soil incubation experiments and isotope labelled substrates with defined energy supply and molecular structures in order to evaluate losses, efficiencies, and the modes of energy and matter retention. It is aimed to combine thermodynamics based analyses and conceptual modelling with time and space resolved sampling. SoilSystems will provide a substantial step forward in understanding energy retention and element cycling in terrestrial ecosystems. Thereby, SoilSystems aims to answer the key-question: What drives the combined energy and matter fluxes in soil exemplified by carbon turnover and storage - the microbiome, the energy input, the mineral and (environmental) boundary conditions, or interactions of all? B) To optimize cooperative research in SPP 2322 all participating projects will benefit from the central management. Soils, substrates and instrumentation for calorimetry will be provided through a common experimental platform. Data are stored and shared on a joint data repository. Research is supported by promoting external cooperation and a Mercator fellow. Project meetings invite for discussion and presentation. Not last specific measures will enable gender equality for full participation in research and academic career
