Effect of nanoparticle of volcanic ash and rock phosphate on some soil chemical properties of variable charge Andisols, Indonesia

open access: yesSoil & Environment, 2018
Andisols is a variable charge soil where fertilizations to the soil do not give the same result as that to the soils with permanent charges. Therefore, amelioration is needed to improve the soil chemical properties.

Potential pitfalls when using popular chemical extractions to characterize Al‐ and Fe‐containing soil constituents

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 730-741, October 2025.
Abstract Wet‐chemical extraction of soil to quantify pedogenic species or to remove specific compounds prior to other analyses is an established approach in analytical soil mineralogy and soil chemistry. Interpretation and informational value of data derived from long‐established and frequently used extractions, for instance involving dithionite ...

Clay minerals in South Australian Holocene basaltic volcanogenic soils and implications for halloysite genesis and structure [PDF]

open access: yes, 2014
The clay mineralogical composition was determined of 8 soils formed from pyroclastic ejecta (tephra) from adjacent 5000-year old basaltic volcanoes at Mounts Gambier and Schank in South Australia.

Evaluating the potential for snowmelt phosphorus losses from perennial forage crops

open access: yesJournal of Environmental Quality, Volume 54, Issue 5, Page 1103-1113, September/October 2025.
Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...

Pedogenesis of a coastal climosequence and a volcanic ash‐influenced elevational transect of western Haleakalā, Maui

open access: yesSoil Science Society of America Journal, Volume 89, Issue 5, September/October 2025.
Abstract The western slope of Haleakalā, Maui, demonstrates a wide range in soil development (eight mapped soil orders), thus providing a unique opportunity to investigate how climate and volcanic ash deposition influence soil development on basalt.
