Dispersible Liquid Nitrogen Fertilizer Additive


Guardian-DL 15-0-0 is a slowly available nitrogen suspension fertilizer for use as an additive to improve the utilization of nitrogen in fluid fertilizers such as suspensions, urea solutions, urea ammonium nitrates (UAN) and liquid manures. Guardian-DL 15-0-0 is a short-term alternative to Conklin’s Guardian-L that is currently unavailable due to raw material shortages. Guardian-DL will be offered for the 2022 growing season.

Comprised of ammoniacal nitrogen and water-soluble nitrogen, which is derived from dicyandiamide (DCD) and ammonium thiosulfate (ATS).

Guard your Nitrogen Investment from Loss Nitrogen can be one of your most expensive inputs. Guard your investment against nitrogen loss with the use of Conklin’s nitrogen stabilization technology—Guardian-DL. With today’s seed genetics, plants require more nitrogen later in the growing season; Guardian-DL holds nitrogen in the root zone over a longer period of time, allowing you to decrease losses, reduce nitrogen application rates up to 20%, and measurably increase crop yields.

This non-toxic formula contains dicyandiamide (DCD), which has world-wide recognition for its use with ammonium-containing fertilizers. Given the limited availability of raw materials during these unprecedented times, Conklin will be offering Guardian-DL 15-0-0 as a nitrogen fertilizer additive to help keep your nitrogen in the root zone longer for the 2022 growing season.

Use 2 quarts per acre for band and soil injection applications and 3-4 quarts per acre for broadcast applications. See the product label for complete directions.


Acres treated per container at 2-quart band application rate:

  • 5-gallon twin pack treats 10 acres (Guardian-L treated 13.3 acres).
  • 250-gallon mini bulk treat 500 acres (Guardian-L treated 666.6 acres).
