Effects of pyrophosphate-extractable aluminum, iron, and calcium on organic carbon storage in buried humic horizons of a cumulative volcanic soil profile containing charred plant fragments, Miyakonojo, Miyazaki, Japan
Charred plant fragments (CPFs), having two primary types (carboxylic and phenolic functional groups) of metal-binding sites, are widely distributed in Japanese volcanic soils containing black humic acids. However, the effects of metal components on the storage of CPFs are still unknown. The aim of t...

| description | Charred plant fragments (CPFs), having two primary types (carboxylic and phenolic functional groups) of metal-binding sites, are widely distributed in Japanese volcanic soils containing black humic acids. However, the effects of metal components on the storage of CPFs are still unknown. The aim of this study was to determine the direct and indirect effects of metal components on the CPF-carbon (CPF-C) and soil organic C (SOC) contents in four buried humic horizons (2A-5A, from 7.3 cal ka BP to AD 1471) of a cumulative volcanic soil profile (Miyakonojo, Miyazaki, Japan), employing correlation, and path analyses. Nineteen soil samples were collected from the humic horizons described above and used. Pyrophosphate-extractable aluminum (Al
py
), iron (Fe
py
), and calcium (Ca
py
), which are common in the soils, were selected as reactive metal components. The CPF-C content accounted for up to 15.1% of the SOC content (8.4% on average). The Al
py
content was highest in all soils, mostly followed by the Fe
py
and then Ca
py
contents. No consistent trends with soil age/depth were found for the accumulation levels of CPF-C, SOC, and metal components. However, there were significant correlations (p |

, and Ca

contents. The result of path analysis showed that a high correlation coefficient between the CPF-C and Fe
py
contents (r = 0.89, p < 0.001) was mainly explained by the direct effect of Fe
py
(0.84, p < 0.01) on the CPF-C content. On the other hand, in the case of SOC, a strong correlation coefficient between the SOC and Al
py
contents (r = 0.93, p < 0.001) was primarily due to the direct effect of Al
py
(0.74, p < 0.01) on the SOC content. The direct effects of Ca
py
on these C contents were not important. Furthermore, significant indirect effects of the metal components on the CPF-C and SOC contents were not observed. From the results obtained, it is assumed that in Japanese volcanic soils, Fe
py
and Al

contribute directly to the large accumulation and stabilization of CPF-C and SOC, respectively.</description><identifier>ISSN: 0038-0768</identifier><identifier>EISSN: 1747-0765</identifier><identifier>DOI: 10.1080/00380768.2024.2389603</identifier><language>eng</language><publisher>Kyoto: Taylor & Francis</publisher><subject>Accumulation ; Acidic soils ; Aluminum ; Andisols ; Andosols ; Binding sites ; black humic acids ; Calcium ; Carbon sequestration ; Correlation coefficient ; Correlation coefficients ; Fragments ; Functional groups ; Humic acids ; Iron ; Metals ; Organic carbon ; Organic soils ; organo-metal interactions ; Phenols ; Plant extracts ; reactive Al, Fe, and Ca ; Soil analysis ; Soil profiles ; Soil properties ; Volcanic soils</subject><ispartof>Soil science and plant nutrition (Tokyo), 2024-11, Vol.70 (5-6), p.387-392</ispartof><rights>2024 Japanese Society of Soil Science and Plant Nutrition 2024</rights><rights>2024 Japanese Society of Soil Science and Plant Nutrition</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c282t-f224cbc558d0d7ee72181e79fb42bd4113cb87b12bbe1f25783cea30b47e60db3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids></links><search><creatorcontrib>Shindo, Haruo</creatorcontrib><creatorcontrib>Inoue, Yudzuru</creatorcontrib><title>Effects of pyrophosphate-extractable aluminum, iron, and calcium on organic carbon storage in buried humic horizons of a cumulative volcanic soil profile containing charred plant fragments, Miyakonojo, Miyazaki, Japan</title><title>Soil science and plant nutrition (Tokyo)</title><description>Charred plant fragments (CPFs), having two primary types (carboxylic and phenolic functional groups) of metal-binding sites, are widely distributed in Japanese volcanic soils containing black humic acids.
