Positive effects of silicification on plant fitness have long been postulated [13], but convincing evidence is lacking so far. Si addition to the growth medium mitigates numerous stresses and can stimulate plant growth [2,6,10], which led to the idea that Si is a growth-promoting, beneficial nutrient overall.Web
