Unravelling upbuilding pedogenesis in tephra and loess sequences in New Zealand using tephrochronology [PDF]

, 2010
The genesis of soils developed in either tephra or loess on stable sites differs markedly from that of soils developed on rock because classical topdown processes operate in conjuction with geological processes whereby material is added to the land ...

Non-allophanic Andosols of Trindade Island, south Atlantic: a new soil order in Brazil [PDF]

Revista Brasileira de Ciência do Solo, 2020
The pedological studies carried out so far in Trindade Island (TI) have obtained patchy evidences of allophane, without detailed mineralogical and micromorphological studies to confirm the occurrence of Andosols in TI.

Capability of Sulphur Oxidizing Bacteria to Inhibit Basal Plate Rot and Increase Shallot Growth on Andisols

AGRIVITA Journal of Agricultural Science, 2019
In the recent years, basal plate rot (BPR) caused by Fusarium oxysporum f. sp.cepae (FOCe) is one of the important constraints of shallot production in Indonesia.

Competitive sorption of molybdate and phosphate in Andisols [PDF]

Journal of soil science and plant nutrition, 2012
Abstract We have examined the effects of both pH and phosphate concentrations on molyb-date sorption by four Chilean Andisols with varying chemical properties. For both anions adsorption decreased with an increase in soil pH and also with organic matter content in the soils. In general, more phosphate than molybdate was sorbed by the soils.

Relationships between land use, fertility and andisol behaviour : examples from volcanic islands [PDF]

, 1999
Soils developed on voIcanic parent materials have many intrinsic qualities favourable to cropping. Howerer, fertility decreases dramatically when they are badly managed.

Charge Characteristics and Cation Exchanges Properties of Hilly Dryland Soils Aceh Besar, Indonesia

Aceh International Journal of Science and Technology, 2020
Soil surface charge and cation exchange are important parameters of soil fertility in tropical soils. This study was conducted to investigate characteristics of surface charges and cation exchanges on four soil orders of the dryland in  Aceh Besar ...

RHIZOBACTERIA AS BIOCONTROL AGENTS OF ROOT ROT DISEASE ON SHALLOT

Sains Tanah: Journal of Soil Science and Agroclimatology, 2015
Shallot is a high-economic value commodity, but so far the supply is still lower than the demand. One of the production problem is “moler” disease of shallot (MDS) caused by Fusarium oxysporum f.sp. cepae (FOCe). The aim of this research was to study the

Characterization of Humic Substance Extracted from Andisols, Spodosols, Peat, and Lignite

Sains Tanah: Journal of Soil Science and Agroclimatology, 2018
Soil and other materials with high C-organic content are potential natural sources of humic substances. Until now the differences in the characteristics of such humic substances that are extracted from different sources have not been widely studied. Thus,

The Role of Soil Microorganisms in Microplastic Biodegradation: Mechanisms, Carbon Preferences, and Ecological Impacts

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This work explores the complex relationship between soil carbon availability and microplastic biodegradation, highlighting competition and symbiosis among microorganisms, the repurposing of microplastic‐derived polymers, and the impact of soil organic carbon on microbial substrate preferences and carbon use efficiency variability.

Role of Nanoclays in Carbon stabilization in Andisols and Cambisols [PDF]

, 2015
Greenhouse gas (GHG) emissions and their consequent effect on global warming are an issue of global environmental concern. Increased carbon (C) stabilization and sequestration in soil organic matter (SOM) is one of the ways to mitigate these emissions ...
