ABSTRACT
Selenium (Se) has many benefits in plant metabolism, yet it is not essential for crops. Due to its importance for humans and animals, Se is one of the target elements of biofortification programs. Food consumed by Brazilians has low Se content. Many studies on Se biofortification of food crops have been conducted in Brazil, yet field data is still limited. This chapter shows that Se biofortification of grain crops in Brazil can be achieved with great success by many different agronomic strategies. This success is relevant not only for assuring food security for the Brazilian population and for those countries that import agricultural products from Brazil, but also beneficial for using best management practices for enriching crops with Se for human health. Rice and beans are staple crops consumed in large scale in Brazil. In Brazil, recent advancements of research on the benefits of Se to cropping systems and human health have led to regulations on selenium-carrying fertilizers.
