Selenium Fertilization of Guinea Grass Pastures in Central Puerto Rico

Abstract

Five levels of selenium (Se) fertilization and a control were tested in a Guinea grass paddock. All treatments followed the same trend: an initial Se concentration increment up to week 6 and then a slow decrease toward initial values or less. No significant differences among treatments or interactions were observed during the 22 weeks of the experiment. The study suggests that soils and forages adequate in Se will not respond to subsequent levels of Se fertilization as Selcote Ultra.
