Impact of Silicon on Plant Nutrition and Significance of Silicon Mobilizing Bacteria in Agronomic Practices

Globally, rejuvenation of soil health is a major concern due to the continuous loss fertility and productivity. Soil degradation decreases crop yields threatens global food security. Improper use chemical fertilizers coupled with intensive cultivation further reduces both yields. Plants require several nutrients in varying ratios that are essential for plant complete healthy growth development cycle. Soil, water, air sources these macro- micro-nutrients needed vegetative reproductive cycles. Among macro-nutrients, nitrogen (N) plays significant non-legume species without sufficient access N lower result. While silicon (Si) 2nd most abundant element Earth’s crust backbone silicate minerals, it an micro-nutrient some plants. Silicon just beginning be recognized as important micronutrient and, while quite abundant, Si often not readily available uptake. The manufacturing cost synthetic silica-based high, absorption silica slow many Rhizosphere biological weathering processes includes microbial solubilization increase dissolution minerals increases availability Therefore, strategy improve uptake could field application Si-solubilizing bacteria. In this review, we evaluate role seed germination, growth, morphological yield under various biotic abiotic stresses, different pools fluxes soil, bacterial genera solubilizing microorganisms. We also elaborate on detailed mechanisms Si-solubilizing/mobilizing bacteria involved by soil. Last, discuss potential solubilizing/mobilizing achieve environmentally friendly sustainable production.
