Non-Agricultural and Special-Use Fertilizer Permits
If you distribute low-analysis fertilizers, you will need either a non-agricultural or special-use permit. Low-analysis fertilizers have less than 24 percent N-P-K. These permits remain in effect until you change the product's label or formulation.
- Non-agricultural fertilizers are used on gardens, lawns, golf courses, greenhouses and nurseries and other non-farm uses, and for research.
- Special-use fertilizers are for product labeled for remedying nutrient deficiencies unique to certain crops or local areas
