- Abstract
- Silicon (Si) is the second most abundant element of the earth crust. The Si cycle strongly depends on the bio-cycling of Si by plants. Plants roots absorb the dissolved silicon (DSi) present in the soil solution and accumulate it into amorphous silica bodies called phytoliths (PhSi). Once plant debris return to soil, PhSi may constitute an important silica pool in soil. PhSi strongly contributes to the DSi pool; especially in desilicated weathered soils. To understand the soil-plant Si cycle it is thus primordial to quantify the PhSi pool in the soil. However, quantification methods are still not very well defined especially in soils in which pedogenic amorphous silica pools are abundant
