GOLD’n GRO® is produced by Itronics Metallurgical, Inc., which operates the only vertically integrated facility in the United States to convert liquid photographic waste into pure silver and GOLD’n GRO® liquid fertilizers. This is creative “clean technology” at its best.

Itronics recycles photochemicals from sources such as hospitals, photo processing centers and data storage companies. After recovering silver and removing other heavy metals from waste products, Itronics supplements the “base liquid” with N-P-K and nutrient metals.

The base liquid is an aqueous solution of mixed thiosulfates, which are highly efficient forms of sulfur. All GOLD’n GRO® fertilizers are ammonium thiosulfate supplemented. A key feature is the presence of EDTA chelating agents; citrate/EDTA chelates are added to improve the ability of plants to extract micronutrients from soil and all products contain guaranteed levels of chelated iron. Low-biuret urea is used to minimize the potential for fertilizer burn and raw phosphate materials are selected for low metal content. Distilled water is used in making the formulations.

Itronics has had a good response to its liquid nutrients since testing began in 1995 at the University of California, Riverside. For example, GOLD’n GRO® 20-1-7 with 0.15% iron and 5% sulfur was the top-ranked fertilizer in two years of comparative turfgrass trials at UC Riverside.

Advantages of using GOLD’n GRO® liquid fertilizers:

• GOLD’n GRO® is 1.5 to 3 times more effective than other products
• Crop production is increased by up to 40%
• Environmentally friendly – reduced fertilizer requirement decreases:
  • Surface run off
  • Soil accumulation
  • Risk of groundwater pollution

Using Itronics’ technology, 50 million gallons of waste photoliquids will produce 100 million gallons of GOLD’n GRO® fertilizer.

GOLD’n GRO® liquid fertilizers are recycling at its best.
