“…En effet, le silicium, par sa rigidité, permet une meilleure disposition des feuilles vis-à-vis du rayonnement solaire et permet donc d'augmenter la capacité de photosynthèse de la plante (Iwata et Baba, 1962 ;Yoshida ef ai, 1969 ;Cock et Yoshida, 1970 4.…”

RésuméLa silice est à la fois constituant essentiel des minéraux des sols et de la composition minérale des végétaux. Elle est en effet intensément recyclée par la végétation où elle est stockée dans les tissus épi-dermiques des feuilles sous forme d'incrustations siliceuses appelées phytolithes.L'étude de cette silice d'origine végétale permet de différencier les écosystèmes forestiers et les teneurs en silice foliaire donnent des informations physiologiques, pédogénétiques, voire sylvicoles et agronomiques, très intéressantes.Ainsi, la teneur en silice foliaire est un bon indicateur de la transpiration de la plante, et par là, un élément de diagnostic pour utiliser certaines pratiques sylvicoles d'irrigation ou d'éclaircies.D'autre part, la silice d'origine végétale (phytolithes) est un bon traceur de l'activité biologique des litières et de l'humus. Ainsi, les phytolithes s'accumulent dans les podzols, à activité biologique ralentie, où elles fixent dans les horizons spodiques Bh une partie de l'azote facilement accessible à l'activité biologique.A l'opposé, les phytolithes sont rapidement biodégradés en milieu biologiquement actif et le silicium rendu ainsi assimilable pour la végétation, permettrait d'augmenter la croissance des peuplements forestiers.

“…One way to avoid the multiplication of experimental trials, especially in the field which can consume a significant amount of time and money. Labcontrolled experiments are fundamental to understand the mechanism, as mentioned before, but once the process is biologically and mathematically described, the use of a model can contribute to predict easier and faster the conditions in which the fertilization will be successful and how much resistance and growth we can except (Cock and Yoshida 1970;Nguyen et al 2016;Ronchi et al 2013). By doing this, it will also be possible to shed some light on other topics such as the line between Si and the other nutrients (Keeping et al 2014;Li et al 2018;Murozuka et al 2014;Xu et al 2020) and how can we adopt agricultural management practices that are sustainable and potentiate the uptake of Si (Klotzbücher et al 2018).…”

Silicon (Si) is a “quasi-essential” element, associated to stresses/limitations alleviation in crops. However, stressful situations are becoming the norm, due to climate change, human exhaustion of natural resources, land degradation and loss of soil biodiversity. In this context, Si becomes a critical element, capacitating crops to grow more and better with less. A total of 467 articles up to 2021 were selected, reporting 501 experiments (lab-oriented and field trials) resulting in 682 cases where different Si-based fertilizers were used to study crops/plants with agronomic value to evaluate its physiological and/or agronomic performance under a specific motivation. Results show that 63% of cases testing Si-fertilization show increase in productivity, while 13% refuted this observation and 24% did not evaluate plant growth. Crop physiological responses was registered in 42% of the cases and only 3% did not report any alteration, although 55% did not evaluate these indicators. Symptom alleviation, in cases where stresses/limitations were studied, was registered in 74% of the cases with a low number of negative outcomes (9%). Field trials where crop yield was measured after application of Si-fertilization show that 69% of different measurements (599) register a yield improvement ≥ 5%, while 18% of the measurements registered between 0 and 5% and only 14% reported yield loss. Si-fertilization is therefore and important factor to improve crop yield and capacitate crops with resilience to endure future limitations. Its inclusion in modern agriculture should be considered in larger scales to adapt crops to the current challenges of sustainable agriculture and food provision.
