The importance of silicon

Interview with Prof. Dirk Van den Berghe Silicon: The missing element While the importance of (Si) in agriculture is poorly accepted, it will be when the consequences of adding (Si) to the soil are properly understood! In the past everyone thought that (Si) was not needed except as an ordinary constituent of the soil. Now it is slowly being accepted as an important beneficial element inside plants for their proper functioning. Silicon (Si) is the second most abundant...

Foliar nutrition of crops: Facts, Myths and Perspectives

Foliar fertilisers are increasingly used in agriculture and new commercial products are continuously released by fertiliser companies as a result of the increasing demand. There is indeed abundant evidence showing the beneficial effects of applying foliar fertilisers as a complementary strategy to soil treatments in terms of improved plant metabolism, yields and quality of crops. However, the current lack of scientific knowledge on many factors associated with the...

Impact of agriculture on the Si biogeochemical cycle

The cycles of C and Si are closely related to the weathering of silicates. In both cycles, terrestrial plants make significant contributions to the weathering budget and soil formation. The perturbation of the terrestrial Si cycle by human occupation has become a challenging issue because of possible impact on the equilibrium of aquatic ecosystems and agriculture sustainability. The recycling of Si stored in plants as phytoliths may control the Si cycle in the short-term. A...

OSA bioavailability cross-over study

Absorption of silicon in healthy subjects Silicon is next to oxygen the most abundant element in the earth’s crust. The distribution of Si deficiency indicate that Si influences bone formation by affecting cartilage composition and ultimately cartilage calcification. The dietary intake of Si was estimated for US citizens to be between 20-50 mg with the lower intake of animal-based diets and the higher intake for plant-based diets. However, studies on the minimum Si...

The therapeutic potential of silicic acid

Review by Christopher Exley, The Birchall Centre, Lennard-Jones Laboratories, Keele University, UK Reflections upon and recent insight into the mechanism of formation of hydroxyaluminosilicates and the therapeutic potential of silicic acid The chemistry of mono or ortho silicic acid (Si(OH)4) is barely considered in most chemistry texts. Mention is usually only made of its autocondensation in forming hydrated amorphous silica and its reaction with ammonium molybdate in...
