In these soils, red iron and aluminum hydroxide and sesquioxide compounds, the residual products of rock decay, have accumulated. |
|
The dichromate is then reduced with carbon to chromium sesquioxide, Cr2O3, and that oxide in turn is reduced with aluminum to give the chromium metal. |
|
Germanium is identified medically as bis carboxyethyl germanium sesquioxide. |
|
It is clear that the effect of SOM on soil properties will vary depending on soil type, clay content, clay type, sesquioxide content, silt content and other soil properties. |
|
This extraction completely recovers elements associated with the exchangeable, organic and sesquioxide fractions and, to a limited extent, the phyllosilicate fraction. |
|
This group of properties relates to the clay, OM, and sesquioxide contents, which are the major sources of variable charge and are more abundant in Oxisols. |
