You can use a vinegar and water solution or a muriatic acid and water solution to remove fertilizer stains from concrete. Muriatic acid may etch concrete, however, so it should only be used if the vinegar and water solution does not work. You will need water, vinegar or muriatic acid and a scrubbing brush or sponge. The minerals in fertilizer stains are not water-soluble and thus cannot be simply removed with water and scrubbing; they need to be treated with an acid solution.
