UNSPSC 10171610: Silica potassium fertilizer

A fertilizer that contains potassium as well as phosphoric acid, silicic acid, magnesia and lime. Silica potassium fertilizer helps reduce cold weather damage and physiological stress on plants.

UNSPSC 10171610 Silica potassium fertilizer is a Commodity code that covers bulk fertilizer procurement by state and local governments for land management and parks operations. Recent solicitations show state and local agencies purchasing granular and liquid fertilizer products in volumes ranging from dozens to hundreds of bags or tons, with delivery to wildlife areas, county parks, maintenance facilities, and specialized operations such as mosquito control. The issuing bodies include state fish and wildlife departments, county parks and recreation divisions, county public works departments, and county stormwater management sections—primarily counties and state natural-resource agencies rather than municipalities or school districts. Work involves straightforward purchase and delivery of new fertilizer products meeting specified formulations and packaging requirements, with pricing quoted on an F.O.B. destination basis and delivery windows typically measured in days to weeks.

Recent activity spans Oregon, Georgia, and Florida. The Oregon Department of Fish and Wildlife solicited quotes for up to 32 tons of fertilizer to Jewell Meadows Wildlife Area with a due date of September 30, 2026 under an intermediate procurement notice; Gwinnett County, Georgia issued an Informal Written Quote on May 13, 2026 for 840 bags of 34-0-0 Ammonium Sulfate to parks and maintenance locations with a May 20 deadline; and Pasco County, Florida posted an Invitation for Bid on May 12, 2026 for herbicides, fertilizers, and pesticides on an as-needed basis through September 30, 2029 with a June 16 bid deadline. Pinellas County, Florida also posted an aerial larvicide application services ITQ on April 23, 2026, though that opportunity focuses on application services rather than fertilizer supply itself. All recent opportunities emphasize firm pricing, F.O.B. destination delivery with freight prepaid or included, and compliance with material safety data sheet and environmental documentation requirements. No specific set-aside designations appear in the solicitations except Pinellas County's preference for Certified Small Business Enterprises on aerial services.
