Itronics GOLD'n GRO Fertilizer Sales up 23 Percent

RENO, NV --(Marketwired - June 22, 2017) - Itronics Inc. ( OTC PINK : ITRO ), a diversified producer of GOLD'n GRO zinc fertilizers and silver products and a green technology development Company, reported today that its January through May 2017 GOLD'n GRO fertilizer sales are up 23 percent compared to the same period in 2016. The fertilizer sales improvement confirms both the end of the drought in California, where the bulk of the fertilizers are sold, and that demand for GOLD'n GRO zinc fertilizers continues to increase.

"The Company sales are returning to levels not seen since the drought in California started five years ago," said Dr. John Whitney, Itronics President. "We are now expecting that sales will continue at higher levels and growth in the customer base will resume."

GOLD'n GRO fertilizers provide improved nutrient uptake by the crops so that smaller quantities can be used compared to competing fertilizers. Over the years field testing has also demonstrated meaningful crop yield improvement. Major crops using the fertilizer include almonds, grapes, cotton, tomatoes and silage corn for dairy cows.

"Improvements in yield and in environmental compatibility are attractive to our distributor and its customers," said Dr. John Whitney, Itronics President. "GOLD'n GRO is a truly 'Green' line of fertilizers manufactured from spent, detoxified, photographic liquid waste."
