Selenium is a vital nutrient for humans, but many people lack it in their diets. Scientists studied how to add more selenium to wheat to make it healthier. They found that wheat can turn harmful selenium into a safer form. By using special techniques, they discovered that selenite goes to the roots, while selenate moves to the shoots. Too much selenium can harm the plant, but applying it at the right time can prevent this. Overall, adding selenium to wheat can make it better for you and help the plant grow well.
