Microstructure and water retention of Oxisols in Thailand
Soil Research, 2005The moisture characteristics and related pore size distributions of Thai Oxisols were determined for 11 representative pedons. These soils are Kandiustox and Kandiudox located in the North-east Plateau, South-east Coast, and Peninsular Thailand. They are generally acidic (pH 5–6), clayey, have low cation exchange capacity (5–15 cmolc/kg) and have low ...

Physical properties of a Mollisol, an Oxisol and an Inceptisol
Soil and Tillage Research, 1990Abstract An Inceptisol (Andept) from Ecuador, an OOxisol (Ustox) from Columbia and a Mollisol (Udoll) from the U.S.A. were studied. The clay in the Andept was >85% amorphous with allophane being predominant. The Ustox contained sesqui-oxides of iron and aluminum and kaolinite, while the Udoll contained hydrous mica, quartz and kaolinite in the clay ...

Soil aggregate hierarchy in a Brazilian oxisol
2002Light and electron microscopy were used to investigate the applicability of the aggregate hierarchy model of Tisdal and Oades [1] to the micromorphology of the A horizon in a Brazilian Xanthic Hapludox soil under both forest and agricultural crop cover. The arrangement of minerals, amorphous material, organic matter, and biota in aggregates of diameter

Liming Potential of Composts Applied To an Acid Oxisol in Burundi
Compost Science & Utilization, 1999The adverse effect of soil acidity on plant growth and yield, and the scarcity of commercial agricultural lime (CaCO3) in Burundi necessitated a search for alternative liming materials. Thus, the liming potential of locally made composts was evaluated in a greenhouse experiment, using an acid Oxisol with sorghum (Sorghum vulgaris) as a test plant ...

Considerations on the evaluation of the fertility of oxisols in Brazil
Chemical Geology, 1987Abstract Based on the analysis of some of the physical and chemical properties of the reddish-colored soils from southeast Brazil four fertility classes of soils were proposed. The soils of class 1 which are characterized by a low inherent fertility are sandy soils which become less fertile after cultivation.

Particle size distribution of Oxisols in Brazil
Geoderma Regional, 2016Abstract Soil texture or particle size distribution is of fundamental importance not only for understanding soil chemical and physical functioning but also for soil classification within a given taxonomic system. The objective of this study was to collect and analyze particle size data of Brazilian “Latossolos” (Oxisols) published in the Brazilian ...

Improving phosphorus availability in Andisols and Oxisols
2016Low phosphorus (P) availability limits plant growth in many soils, particularly in Andisols and Oxisols, due to their large content of minerals that strongly sorb P (e.g. Al/Fe oxyhydroxides, allophane). Because of the strong P retention, P fertilizer requirements are high in these soils.
