2024年6月22日 · Soil organic carbon (SOC) persistence is predominantly governed by mineral protection, consequently, soil mineral-associated (MAOC) and particulate organic carbon (POC) turnovers have different...

2022年8月29日 · Here, we explore how the functionally distinct fractions, including particulate and mineral-associated organic C (POC and MAOC) as well as iron-bound organic C (OC-Fe), respond to permafrost...

2024年11月12日 · 特别是在不同干旱条件下，土壤中的颗粒有机碳（poc）和矿物结合有机碳（maoc）的响应机制尚未完全阐明。 因此，研究干旱对SOC及其组分的影响，对于理解全球 碳 循环和应对气候变化具有重要意义。

5 天之前 · a, c Effects of N fertilization on POC and MAOC across four field experiments. Asterisk indicate a statistical significance of the effect based on non-parametric Wilcoxon test (P < 0.05) using the ...

2021年11月1日 · Investigating SOC responses to global changes separately for mineral-associated organic carbon (MAOC) and the particulate organic carbon (POC) can aid in the understanding of overall SOC responses, because these are formed, protected, and lost through different pathways.

2023年4月18日 · Particulate organic carbon (POC) and mineral-associated organic carbon (MAOC) are currently popular methods for the fractionation and analysis of SOC. Nitrogen (N) addition affects SOC dynamics. However, the characteristics of POC and MAOC and their potential drivers under N (inorganic and organic N) addition remain unclear.

In this study, soil samples were collected from depths of 0–100 cm at eight sites located between 18° and 48° north latitude in eastern China. The soil samples were then separated into particulate organic matter (POM) and mineral-associated organic matter (MAOM) based on particle size to analyze the distribution of C within each fraction.

土壤有机碳（soc）持久性主要受矿物保护控制，因此，土壤矿物相关（maoc）和颗粒有机碳（poc）周转对土壤有机碳对气候变化的脆弱性有不同的影响。 在这里，我们使用 8341 个观测值生成全球 MAOC 和 POC 地图，然后通过数据模型集成方法推断 MAOC 和 POC 的周转 ...

2025年3月19日 · The MAOC and POC soil samples were dried, ground into a powder using a ball mill, and placed in tin capsules for organic C content (%) and 13 C/ 12 C ratio measurements using a continuous-flow gas isotope ratio mass spectrometer. Total SOC and total nitrogen levels were determined using a Vario MACRO cube elemental analyzer (Elementar, Bremen ...

2023年1月1日 · SOC fractionation, such as the separation of mineral-associated OC (MAOC) and particulate OC (POC), has been proposed when analysing the processes and mechanisms of OC stabilization in soils (Cambardella and Elliott, 1992, Cotrufo et al., 2019).
