Warming and humidification mediated changes of DOM composition in an Alfisol

Science of The Total Environment, 2022
Dissolved organic matter (DOM) represents the most mobile and reactive pool of soil organic matter (SOM). Climate changes, such as global warming and altered precipitation exert considerable influences on the quality and quantity of soil DOM. However, rare reports have focused on the interactive effects of soil warming and increased precipitation.

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.

Acidification of a cultivated Alfisol in Venezuela

Communications in Soil Science and Plant Analysis, 1999
Abstract A moderately acid sandy clay Alfisol was used to grow corn as a monoculture for twenty years using urea fertilization. Successive samplings were performed during crop growth over the last two years (1993 and 1994) in the upper two soil layers (0–20 cm and 20–40 cm) of the control plot where the addition of urea had been interrupted and in a ...

Transport of Inorganic Phosphorus in an Alfisol

Soil Science Society of America Journal, 1979
Abstract Adsorption, desorption, and movement of phosphorus in an Alfisol soil were characterized by miscible‐displacement and batch‐type experiments. The influence of pore‐water velocity, aggregate size, and pretreatment of the soil with P was evaluated. A model which considers the interaction of P with soil as an equilibrium kinetic

Bentonite as an Ameliorant in an Alfisol—A Laboratory Study

Journal of Irrigation and Drainage Engineering, 2001
Bentonite, a commercially available clay mineral, can be used for increasing the water holding capacity of the soil and as a sealant material. Laboratory studies were conducted with the amended soil using bentonite as an ameliorant. The mixtures were prepared with the additives on a volume basis.

Soil erosion on Alfisols in Western Nigeria

Geoderma, 1976
Abstract The effect of slope, crop rotation and residue management on runoff and soil loss was investigated using field runoff plots of 25 m × 4 m on natural slopes of 1, 5, 10 and 15% on an Alfisol on the International Institute of Tropical Agriculture (IITA) research site near Ibadan, Nigeria.

Trace Elements in Manganese‐Iron Nodules from a Chinese Alfisol

Soil Science Society of America Journal, 2002
The morphological properties, the mineralogy, and the chemical composition of Mn‐Fe nodules, collected from an Alfisol in Southern China (Wuhan), were studied by optical microscopy (OM), transmission electron microscopy (TEM), and scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), total and sequential dissolution chemical ...

Phosphorus Fractions and Availability in Sri Lankan Alfisols

Soil Science Society of America Journal, 1992
Abstract Phosphorus is the second most limiting element in the Alfisols of tropical Asia and Africa. The relationships between P fractions in 12 Sri Lankan Alfisols and P taken up by plants in a greenhouse experiment and P removed by five chemical extractants were examined.
