Silicon (Si) has recently been recognized as a quasi-essential element in plant nutrition. Some plant species, such as diatoms and equisetum, can not grow without silicon. Other plants benefit from silicon nutrition to various degrees depending on the environmental conditions. Rice, wheat, cucurbits, and sugarcane are examples of crops that often benefit from enhanced levels of silicon nutrition. In crop production the benefits from silicon may include increased yield, disease and insect resistance, and tolerance to stresses such as cold, drought, and toxic metals.  In addition to plants, the value of silicon is gaining attention in animal nutrition where silicon has been shown to play a role in the health of bone, joints, skin, hair, and other connective tissues. Read more here
