Contribution towards a morphological and molecular taxonomic reference library of benthic marine diatoms from two Arctic fjords on Svalbard (Norway)
Knowledge on benthic diatom taxonomy and hence biodiversity from Arctic locations is rare, though the few existing analyses address morphological characteristics only. Morphological treatment is a time-consumi...

Silicon cycle in rice paddy fields: insights provided by relations between silicon forms in topsoils and plant silicon uptake
Silicon (Si) enhances the stress resistance of rice plants. Silicon cycling in paddy fields is, however, still poorly studied. We examined relationships between Si forms in topsoil and plant Si uptake for four...

Interaction between silicon cycling and straw decomposition in a silicon deficient rice production system
Rice plants (Oryza sativa L.) contain large quantities of silicon (Si) in form of phytoliths, which increase their resistance to abiotic and biotic stresses. The Si cycle through rice fields is hardly studied. We...

Forms and fluxes of potential plant-available silicon in irrigated lowland rice production (Laguna, the Philippines)
Silicon (Si) is beneficial for rice plants. It increases their resistance against pests and diseases. Although Si uptake of rice crops is often higher than nitrogen uptake, studies on forms and fluxes of plant...
