Much research focuses on increasing carbon storage in mineral-associated organic matter (MAOM), in which carbon may persist for centuries to millennia. However, MAOM-targeted management is insufficient because the formation pathways of persistent soil organic matter are diverse and vary with environmental conditions. Effective management must also consider particulate organic matter (POM). In many soils, there is potential for enlarging POM pools, POM can persist over long time scales, and POM can be a direct precursor of MAOM. We present a framework for context-dependent management strategies that recognizes soils as complex systems in which environmental conditions constrain POM and MAOM formation.

Bioclogging from organic accumulation significantly limits efficiency and longevity of constructed wetlands (CWs). In this study, hematite was introduced to enhance the oxidation of organics by dissimilatory iron reduction (DIR). Compared to gravel CWs (G-CWs), hematite CWs (H-CWs) enhanced the removal of COD, ammonium, and phosphate by 12 %, 46 %, and 72 %, while reducing CH and NO emissions by 69 % and 36 %.

Black soldier fly (BSF) organic fertilizer is known to enhance soil fertility and promote plant growth. However, its effects on soil carbon (C) and nitrogen (N) cycling remains unclear. In this study, we established a BSF chicken manure bioconversion system to produce BSF organic fertilizer and investigate its impacts on soil C and N cycling, as well as microbial ecological networks through metagenomic analysis.

This review examines the chemical and ecological interactions between filter-feeding mussels and the green macroalga Ulva prolifera in integrated multi-trophic aquaculture (IMTA) systems. Mussels are crucial for nutrient recycling, as they filter water and release bioavailable compounds such as ammonium (NH), urea (CO(NH)), and dissolved organic matter (DOM). These compounds promote Ulva growth and enhance microbial activity.

Large-scale anaerobic treatment involves a high risk of antibiotic pollution in anaerobically digested (AD) biosolids, which hinders the efficient utilization of farmland AD biosolids. Herein, a process for the in situ removal of antibiotics from AD biosolids using ethylenediaminetetraacetic acid disodium salt dihydrate as the release agent synergized with sodium persulfate oxidation is reported. The developed process was used to remove antibiotics from actual AD biosolids.

Tidal estuaries serve as critical zones for biogeochemical connectivity between terrestrial and oceanic ecosystems. With climate change magnifying the impact of flood events on riverine system, dissolved organic matter (DOM) cycling, the largest reactive elemental pool in ecosystems, in tidal estuaries tend to be more complex and remain poorly understood. To address this gap, the response of DOM dynamics to flood events in a typical tidal estuary was explored.
