“…This includes pyroclastic materials deposition of < 2 mm tephra fractions (it includes sand, silt and clay particles in conventional texture analysis) which is often directly referred to as 'volcanic ash' (Arnalds 2013;Fuentes et al 2020;Müller et al 2019;Rossi et al 2021;Suh et al 2019), and subsequent volcanic ash movement in the landscape (Anda et al 2016;Ayris and Delmelle 2012;Zobel and Antos 2017). Parts of the literature on volcanic soils describes long-term soil genesis (Babiera and Takahashi 1997;Dahlgren and Ugolini 1989;Fiantis et al 2021;Fiantis et al 2017;James et al 2016;Ontiveros et al 2016;Schlesinger et al 1998). Other authors have a focus on the short-to-medium term consequences for vegetation dynamics (del Moral and Lacher 2005;Magnin et al 2017;Swanson et al 2016;Zobel and Antos 2017), the hydrological characteristics and sedimentation in the drainage basin (Hendrayanto et al 1995;Leavesley et al 1989;Major et al 2009;Manville et al 2009;Pierson and Major 2014), or soil development and biological communities (Fernández et al 2018;Ferreiro et al 2018;Fiantis et al 2019;Fiantis et al 2016;Tateno et al 2019;Yamanaka and Okabe 2006).…”

Background and purpose Volcanic eruptions of pyroclastic tephra, including the ash-sized fraction (< 2 mm; referred to as volcanic ash), have negative direct impacts on soil quality. The intensity (deposit thickness, particle-size distribution) and frequency (return period) of tephra deposition influence soil formation. Vulnerability and subsequent recovery (resilience) of the plant-soil system depend on land-uses (vegetation and management). Few previous studies covered the whole deposition-recovery cycle. We investigated the volcanic ash deposition effects on soil properties and their recovery across land-uses on a densely populated volcanic slope. Methods We measured the canopy cover and volcanic ash thickness six years after the 2014 Mt. Kelud eruption in four land-use systems: remnant (degraded) forests, complex agroforestry, simple agroforestry, and annual crops. Each system was monitored in three landscape replicates (total 12 plots). For the soil recovery study, we measured litter thickness, soil texture, Corg, soil C stocks, aggregate stability, porosity, and soil infiltration in three different observation periods (pre-eruption, three, and six years after eruption). Results Post-eruption volcanic ash thickness varied between land-use systems and was influenced by the plots slope position rather than canopy cover. The average soil texture and porosity did not vary significantly between the periods. Surface volcanic ash and soil layers initially had low aggregate stability and limited soil infiltration, demonstrating hydrophobicity. While Corg slowly increased from low levels in the fresh volcanic ash, surface litter layer, aggregate stability, and soil infiltration quickly recovered. Conclusions Different land-use management resulted in different recovery trajectories of soil physical properties and function over the medium to long term after volcanic ash deposition.

“…Desilication Index (DI= SiO 2 /(Fe 2 O 3 + Al 2 O 3 + TiO 2 ), a method that assesses the degree of weathering by comparing mobile silica with resistant oxides (titanium oxide) was also used to assess weathering (Stockmann et al, 2016). The lower the DI value, the more optimal the level of weathering (Fiantis et al, 2017).…”

A quarry in the Chobe Enclave, northern Botswana, exposes a prominent pedostratigraphic unit of approximately 8 metres consisting of two pedostratigraphic levels (PL), older PL1 and younger PL2. In a region where proxies for palaeoenvironmental reconstruction are terribly lacking, this study assessed the potentials of paleosols (fossil soils) to answer fundamental questions about weathering, pedogenic intensity and environmental change using macromorphology, geochemistry and clay mineralogy. SiO2 is the dominant major oxide (40.6- 98.9 wt. %) followed by CaO (0.02-29.6 wt. %), Fe2O3 (0.48- 2.64 wt. %), MgO (0.14 – 1.81 wt. %) and Al2O3 (0.29 – 0.93 wt. %). The clay-sized minerals present in the paleosols are sepiolite, quartz, calcite and kaolinite. The carbonates had strong positive correlation with Sr (R2 = 0.935), while Fe2O3 had weak positive correlation with TiO2 (R2 = 0.0187). PL1 developed on materials of fluvial origin and is genetically immature with A/C horizons. In comparison with modern soil, PL1 would qualify as Entisols (Fluvent or Fluvaquent in Soil Taxonomy). PL2 is comparable to modern Calsisol and formed from protracted period of post burial dissolution, downward translocation and recrystallization of the palustrine carbonates to form pedogenic carbonates. Calcification, incipient ferralization and leaching of soluble salts are the dominant pedogenic processes in the pedostratigraphic section. Weathering and pedogenesis were generally incipient in the unit. Late Quaternary hydrological dynamics in the Chobe Enclave was the major driver for the formation of the soil stratigraphic unit. This study demonstrates the applicability of paleosols for reconstructing and discerning palaeoenvironmental and climate dynamics and gives the possibility of connecting pedosedimentary processes in the area to regional palaeoenvironmental archives.

[SPATIAL ANALYSIS OF MATERIAL DISTRIBUTION AND CHEMICAL PROPERTIES OF VOLCANIC ASH FROM THE ERUPTION OF MT. SINABUNG IN 2019]. Mount Sinabung, located in Karo Regency, North Sumatra, first erupted in August 2010 and continued from 2013 to 2022. As one of the parent materials for fertile soil, volcanic ash reserves large amount of nutrients. The research was aimed to determine the chemical characteristics of volcanic ash and to map the distribution of volcanic ash from Mt. Sinabung eruption material in 2019. This study examines 22 samples of the of volcanic ash collected based on a terrestrial survey with the grid method. The results showed that volcanic ash within a radius of 3-5 km from the center of the eruption (total area 1,402.83 ha) have a pH-H2O ranged from 5.30 to 6.27 (acid to slightly acid), Mg > Na > Ca > K, in order of base cations, with moderate to very high criteria, available P ranged from 35 – 165.96 mg/kg (very high), and CEC ranged from 12.92 – 21.78 cmol/kg considered low to moderate. Therefore, the volcanic ash deposits can provide a significant quantity of nutrients for future soil fertility in agricultural areas affected by eruptions.
