UNSPSC 10171500: Organic fertilizers and plant nutrients

UNSPSC 10171500 Organic fertilizers and plant nutrients is a Class code covering soil amendments and fertilizer products applied in landscaping, roadside vegetation management, and plant establishment work. State and local governments procure these materials primarily for transportation departments managing rights-of-way, parks and recreation departments, and public works divisions tasked with roadside beautification, erosion control, and vegetation establishment after construction or land disturbance. The work typically bundles organic fertilizer application with soil preparation, mulch installation, and plant establishment services rather than appearing as a standalone materials purchase — reflecting how fertilizer and plant nutrients integrate into broader landscape construction and maintenance contracts. Issuing bodies range from state transportation departments to county and municipal public works and parks agencies, each managing vegetation on public property.
