Reno — While Itronics Inc. said that Gold’n Gro fertilizer revenues for the first quarter 2012 were off 30 percent from the year-ago quarter, it said some $172,000 in fourth-quarter 2010 orders were carried into first quarter 2011, making the year-ago revenues appear larger. Without these sales, the 30 percent drop in revenues was really a 19 percent increase. First-quarter fertilizer revenues were $294,132, down from the year-ago $419,291. Company-wide, Itronics revenues were up in the first quarter, to $572,500 from the year-ago $511,382. This was due to the company’s silver division, where revenues soared 226 percent, to $231,272 from the year-ago $70,962.
