What is Silicon Dynamics Through the Lens of Soil-plant-animal Interactions: Perspectives for Agricultural Practices about?

Background Silicon (Si) is increasingly recognized as a pivotal beneficial element for plants in ecology and agricultural sciences, but soil-plant Si cycling has been considered mostly through the prism of abiotic mineral weathering, whilst numerous biological processes have been overlooked. Leveraging ecological processes that impact soil-plant Si cycling in cropping systems might improve crop Si status, but this remains hypothetical to date. Scope We aim to comprehensively compile information about biotic and abiotic processes driving soil-plant Si cycling, and translate their potential beneficial effects in agricultural practices. We emphasize the fundamental need to consider the effects of agricultural practices on Si mobility in soil-plant systems when striving towards sustainable agroecosystems. Conclusions Regarding soil abiotic factors, degree of soil weathering, mineralogy, texture and pH are key predictors of soil Si dynamics, while soil aggregation processes deserve further investigation. The biological processes associated with mycorrhizal associations, silicate-solubilizing bacteria, and soil macrofauna enhance Si mobility in soil-plant systems, while the effect of roo
