malt dust (uncountable)

  1. Fine particles of malt, or of the grain used in making malt; used as a fertilizer.
    • 1813, Sir Humphry Davy, Elements of Agricultural Chemistry in a Course of Lectures:
      Malt dust consists chiefly of the infant radicle separated from the grain. I have never made any experiment upon this manure; but there is great reason to suppose it must contain saccharine matter; and this will account for its powerful effects.
