本研究は、旧製粉所池の堆積物から発達した土壌における全有機炭素（TOC）と全窒素の含有量とストック、および易分解性画分の割合を分析した。結果、表層50cmで平均18.1 kg m−2、全層で平均43.7 kg m−2の高いTOCストックが確認され、溶存有機炭素の割合は平均1.06%と低く、難分解性画分が多いことが示された。これは土壌炭素の安定性と持続可能な土地利用に重要な知見を提供する。
English
This study analyzed total organic carbon (TOC) and nitrogen contents and stocks in soils developed from former mill pond sediments. High TOC stocks were found (mean 18.1 kg m−2 in top 50 cm, 43.7 kg m−2 in whole profile), with low labile fractions (mean DOC 1.06%), indicating recalcitrant organic matter and low degradation potential. These findings are crucial for sustainable land management and carbon sequestration.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、休耕田やため池の陸化など、土地利用変化に伴う土壌炭素ストックの評価が重要視されている。本研究の手法は、国内の同様のサイトにおける炭素貯留能評価に応用可能であり、カーボンニュートラル達成に向けた土壌炭素隔離の定量化に貢献する。
In the global GX context
Globally, soil organic carbon stocks are critical for climate change mitigation and sustainable land management. This study provides empirical data on carbon stocks in anthropogenically influenced soils, contributing to the understanding of carbon sequestration potential in managed landscapes. The findings support international efforts to include soil carbon in climate reporting and carbon accounting frameworks.

📄 Abstract（原文）
The basins of former mill ponds are a common element of the cultural landscape, while soil science studies focusing on mill pond sediments remain relatively rare. One of the key properties relevant to the sustainable management of these sites is the content and stocks of organic carbon in the soils developed from the mill pond sediments. Therefore, the study aimed to analyze the total organic carbon (TOC) and total nitrogen content, as well as its stocks in the studied soils, the share of the labile fractions of these compounds in relation to the environmental factors influencing these properties and finally their potential changes over time (stability). The obtained results confirmed that the studied soils (mostly classified as Gleyic Fluvisols and Fluvic Phaeozems) are characterized by a high amount of TOC. This manifests in the large TOC stocks in the upper 50 cm (mean = 18.1; min = 8.35; max = 35.5 kg m−2) and in the whole soil profiles (mean = 43.7; min = 10.6; max = 93.6 in kg m−2). The dissolved organic carbon share in TOC content was slightly over 1% on average (mean = 1.06; min = 0.19; max = 4.75) and the specific UV absorbance averaged about 2.40 L mg C−1 m−1, indicating the relatively large proportion of recalcitrant organic fractions and low potential for further degradation.
