Alfisols, Vertisols, and Andisols

2020
Collectively, Alfisols, Vertisols, and Andisols comprise a small proportion of the soil series and the land area in Nevada. This chapter discusses the distribution, properties and processes, and use and management of soils in these three orders in Nevada.

Adsorption of Sulfate and Phosphate on Andisols

Communications in Soil Science and Plant Analysis, 2003
This research studied the factors influencing the adsorption of phosphate and sulfate added alone or as a mixture on Andisols with different chemical, physico-chemical, and mineralogical properties and the desorption of sulfate (and phosphate) previously fixed on selected soil samples by increasing concentrations of phosphate (and sulfate).

Lytell Series: A Nonvolcanic Andisol

Soil Science Society of America Journal, 1987
Abstract In 1978, a proposal was made to form a new order of Andisols in Soil Taxonomy . This new order would allow greater recognition of the unique properties of soils that developed in volcanic tephra.

Andisols of Deserts in Iceland

Soil Science Society of America Journal, 2001
Desert areas cover 35 to 45000 km 2 of Iceland or about 35 to 45% of the country. These surfaces have very low vegetation cover as a result of several environmental factors and anthropogenic impacts.

Inheritance of 2:1 Phyllosilicates in Costa Rican Andisols

Soil Science Society of America Journal, 1994
Abstract The occurrence of 2:1 phyllosilicates in Andisols is variously ascribed to in situ pedogenic origin, aeolian addition, or the presence of hydrothermally altered rock fragments. We studied the origin of 2:1 phyllosilicates that occur in Holocene Hapludands on andesitic, sandy beach ridges in Costa Rica by micromorphological ...

Electrokinetic determination of the buffer capacity of Andisols

Science of The Total Environment, 2007
Among methods which involve the flow of electric current, the electro-remediation techniques have shown useful both for the removal of polluting species, and for obtaining a series of parameters in relatively laboratory simple experiments which can be used to characterize soils.

Relationship between stable carbon and nitrogen isotope ratios of humic acids extracted from Andisols and non-Andisols

CATENA, 2015
Abstract To relate the isotopic composition of soil humic acids (HAs) to their source plants and their degree of humification (as indicated by the degree of darkening), as well as to soil type, we determined the stable isotope ratios for carbon (δ13C) and nitrogen (δ15N) of HAs extracted from 26 virgin soil samples (14 Andisols and 12 non-Andisols ...

Some Andisols from Savai'i, Western Samoa

Soil Science Society of America Journal, 1991
Abstract Five pedons in the lowlands and foothills of Savai'i were studied in detail to determine whether or not they were Andisols. All five met the requirements proposed by the International Committee for the Classification of Andisols (ICOMAND) for the designation of Andisols, as recently accepted into the soil taxonomy.

Separation of melanic and fulvic andisols

Soil Science and Plant Nutrition, 1988
Abstract It has been recognized in Japan and Alaska that vegetational effects in particular, of grass and forest ecosystems contribute significantly to the formation of melanic and fulvic Andisols, respectively (SHOJI et al. 1988a, b). Although the two Andisols have thick, humus-rich horizons, they indicate remarkable differences in the humus ...

Andisols from Four Different Regions of Iceland

Soil Science Society of America Journal, 1995
Abstract Limited information has been published on Andisols in Iceland, but such data are important for understanding the erosional and periglacial processes that are intense in Iceland. The objectives of this research were to investigate Andisols that developed in tephra and eolian materials and that are highly ...
