Responses of earthworm to aluminum toxicity in latosol

Environmental Science and Pollution Research, 2012
Excess aluminum (Al) in soils due to acid rain leaching is toxic to water resources and harmful to soil organisms and plants. This study investigated adverse impacts of Al levels upon earthworms (Eisenia fetida) from the latosol (acidic red soil). Laboratory experiments were performed to examine the survival and avoidance of earthworms from high Al ...

Molybdenum Deficiency in Latosols of Java

Nature, 1957
RECENT experiments with groundnuts, Arachis hypogea, on the Muara plots near Bogor, Java, have shown that small applications of molybdenum produce a markedly beneficial effect on the colour and growth of this legume when grown on latosols of this area. The beneficial effect was not confined to one soil mapping unit in the plot field, and since latosols

Mineral Content of a Latosolic Brown Forest Soil and a Humic Ferruginous Latosol of Hawaii

Soil Science Society of America Journal, 1955
Abstract Mineralogical analysis for two soils representing the Latosolic Brown Forest and Humic Ferruginous Latosol groups were made using X‐ray, thermal, and chemical techniques. In the A horizon of the Latosolic Brown Forest soil goethite (28%) was the predominant mineral; in the B horizon gibbsite (42 ...

Characteristics and Genesis of Low Humic Latosols

Soil Science Society of America Journal, 1959
Abstract The soils belonging to the great soil group of Low Humic Latosols have developed on basic crystalline rock materials in a semiarid to subhumid climate of subtropical and tropical regions having a pronounced dry period. The soil profiles of this group are characterized by the development of a weak A

Origin of the Term Latosol

Soil Science Society of America Journal, 1975
Abstract The term Latosol was coined in 1947. The general concept resembles that of Oxisol in current taxonomy, but the two terms are far from equivalents.

Barium isotopic fractionation in latosol developed from strongly weathered basalt

Science of The Total Environment, 2019
Weathering is a key process in the transfer of material from continents to the hydrosphere. A latosol profile in Zhanjiang, Guangdong Province, South China, formed through intense weathering of basalt, was studied to improve understanding of Ba isotopic fractionation during basalt weathering.

Baseline Concentration of Heavy Metals in Brazilian Latosols

Communications in Soil Science and Plant Analysis, 2003
Knowledge of baseline concentrations for heavy metals of environmental and agricultural concern in tropical soils is meager. Latosols are highly weathered soils that cover ∼40% of the Brazilian territory and are by far the most important agricultural soil order in Brazil.

CATALYTIC POLYMERIZATION OF PHENOLIC COMPOUNDS BY A LATOSOL

Soil Science, 1978
Twelve phenolic compounds and glycine were mixed in two different formulations, designated as A and B, and dissolved in adequate amounts of very dilute NH4OH. Formulation A contained fewer trihydroxyphenolic compounds and more dihydroxypenolic compounds than formulation B.

Nitrogen fixation in latosolic soil under grass

Plant and Soil, 1963
Four latosolic soils, varying in total nitrogen content from 0.050 to 0.098 per cent and in organic matter from 0.95 to 1.56 per cent, were collected from the farm of University College, Ibadan, Nigeria. No change in nitrogen content was observed when the soils were kept moist in the greenhouse for four months. Where a legume (Centrosema pubescens) was

Strength attributes and compaction susceptibility of Brazilian Latosols

Soil and Tillage Research, 2009
In this study, strength attributes and compaction susceptibility of the main classes of Brazilian Latosols (Oxisols), under native vegetation, were studied using the load bearing capacity models relating precompression stress, compression index and water potential through statistical regression models.
