Desilicationdoi:10.1007/978-1-4020-3995-9_155Desilication (or desilicification) is the removal of silicon from a soil or soil horizon, relative to some less mobile component or components. Characteristic of pedogenesis in the humid tropics...Springer Netherlands...
On the basis of analysing the chemical constituents, free iron oxide and clay mineral of 9 soil samples of 3 soil profiles and their parent rocks on Weizhou,Yuwan and Xicun islands; we studied preliminarily the desilicification and allitization of soils on the islands. 在对涠洲岛、渔岛和西...

One silicate bacteria strain SDB6 with good performance in silicon removal was isolated and screened from soil.Based on the morphological,physiological,biochemical characteristics and 16S rDNA sequence analysis,SDB6 was identified as Bacillus mucilaginosus strain.The effects of nitrogen source,pH,...
Guadeloupe► The δ30Si ratio in the clay fraction depends on the degree of soil desilication. ► Lighter Si isotope compositions in kaolinite than in smectite relative to andesite ► Insights to define δ30Si as a proxy for environmental conditions for clay formation...
Our results clearly show that crop straw recycling not only prevents anthropogenic desilication (about 43-60% of Si exports can be saved by crop straw recycling in the long term), but also replenishes plant available Si stocks of agricultural soil-plant systems. Furthermore, we found that a...

Results show that, as with modern soils, neoformation of secondary clay minerals in the paleosol was associated with the fractionation of Si isotopes and Ge/Si ratios in response to chemical weathering and soil desilication. Furthermore, the loss of Fe-bearing minerals, most likely Fe-bearing ...
In this study, a bacteria strain with desilication ability on fly ash was isolated from the soil and identified as Bacillus amyloliquefaciens by 16sRNA and named ZGW-12. Through the bio-leaching treatment of fly ash by ZGW-12, it was found that the concentration of Si was 306.26mg/L and...
