Efficiency of selenium agronomic biofortification: II. The influence of the form of selenium

Selenium is a metalloid and exist in different oxidation stages: selenate (Se6+), selenite (Se4+), selenide (Se2-) and elemental selenium (Se0). Se is essential for humans, but beneficial to plants. Because of low Se content in soil, the most food of plant origin is also poor in Se and therefore human diet does not provide enough selenium. Se is similar to sulfur (S) and uses its path to enter the plant. Se is found in organic and inorganic form. The main organic forms are selenomethionine (SeMet) and selenocysteine (SeCys). Selenate and selenite are the most commonly used forms of Se for fertilization. Selenate is more effective to increase total Se content in plants compared to selenite.
