Non-Agricultural and Special-Use Fertilizer Permits

  • 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
