UNSPSC 10171606: Pure silica fertilizer

A fertilizer that has the soluble silicate as the main ingredient.

UNSPSC 10171606 Pure silica fertilizer is a Commodity code covering fertilizer products and related application services that state and local governments procure for parks and recreation maintenance, athletic field management, agricultural operations, and mosquito control programs. The recent solicitations under this code show a much broader scope than the code's pure silica title suggests: Gwinnett County, Georgia solicited ammonium sulfate in bulk bags for parks maintenance; Pasco County, Florida sought herbicides, fertilizers, and pesticides on an as-needed basis; the Illinois Department of Agriculture purchased MAP, DAP, potash, micronutrients, and nitrogen products for research farms; and White County, Georgia sought integrated chemical application services including fertilizer, weed control, and insect management at recreational facilities. The issuing bodies span county governments (Gwinnett, Pasco, Pinellas, Palm Beach in Florida and Georgia), state agricultural departments (Illinois), and smaller municipal park authorities. Counties appear as repeat buyers, particularly in Florida where multiple counties manage large-scale landscape and turf chemical programs.

Recent activity concentrates in Florida and Georgia, with secondary presence in Illinois. Gwinnett County issued an Informal Written Quote (IWQ 130290) on May 13, 2026 for 840 bags of 34-0-0 ammonium sulfate with a May 20, 2026 response deadline and expected award value under $2,500. Pasco County, Florida posted an Invitation for Bid (IFB-SP-26-074) on May 12, 2026 for herbicides, fertilizers, and pesticides on an as-needed basis with a June 16, 2026 deadline, a three-year contract term through September 2029 with optional two-year extensions, and no disclosed award value. Pinellas County Public Works issued an Invitation to Quote (ITQ #26-0443-ITQ) on April 23, 2026 for aerial larvicide application services at approximately $100 per acre on a 12-month term with estimated annual value of $400,000 and available Certified Small Business Enterprise preference. The Illinois Department of Agriculture conducted small-purchase procurements in March 2026 for fertilizers and seeds at the Zell Farm and White Farm research sites with rapid turnaround deadlines. Palm Beach County established a pre-qualified vendor list (RPQ 68023003CR13) posted in January 2026 for ongoing chemical supply with anticipated 60-month contract value of $900,500, incorporating Equal Business Opportunity preferences for small and minority-owned vendors and five percent local preference for Palm Beach County–based firms.
