NIGP 33533: Chemical Root Stimulators

NIGP 33533 Chemical Root Stimulators is an Item code under which state and local governments procure fertilizers, chemical soil amendments, and specialized turf maintenance products for parks, athletic facilities, golf courses, and municipal grounds. Recent solicitations show that buyers under this code are purchasing fertilizers, sand mixes, compost, drainage stone, sod, and vegetation management chemicals on a recurring basis, typically under annual or multi-year contracts with as-needed consumption models. Issuing bodies soliciting under the code include municipal parks departments and township grounds management offices, which tend to bundle root stimulators and related turf products into larger turf-supply or grounds-maintenance agreements rather than as standalone chemical procurements. Bidders must meet detailed technical specifications for particle size, pH, soluble salt content, and screening, and must supply Safety Data Sheets where required; product substitutions are permitted when accompanied by complete manufacturer documentation and written clarification of any specification deviations.

Recent activity appears concentrated in the Southwest and Mid-Atlantic regions. Pennsauken Township, New Jersey posted solicitation 2026BID12 for turf supplies serving the Pennsauken Country Club with bids due August 27, 2026 via the Township's eProcurement Portal; the contract carries a two-year term with options for extension and allows the Township to award individual line items to separate bidders. The City of Peoria, Arizona issued bid solicitation P260071 on June 12, 2026 for fertilizer and chemical products across multiple municipal parks and right-of-way properties within Maricopa County, with response due July 3, 2026. Both solicitations specify delivery to the customer's locations and include pricing models that bundle delivery costs into the bid rather than charging separate fuel surcharges.
