Important Information

  • Application and advice

    Selprill Double prills are either blended with fertiliser or can be applied as-is. It should be applied during periods of good pasture growth rates such that the selenium is taken up by the growing pasture. Because Selprill Double releases selenium over 12 months, the timing of application is not critical.

    Mixing Rates: Apply no more than 0.5kg/ha of Selprill Double.
