The state Department of Environmental Conservation issued a notice Tuesday that the 2012 Dishwasher Detergent and Nutrient Runoff Law prohibits the use of phosphorus fertilizers unless a new lawn is being established or a soil test shows that the lawn does not have enough phosphorus.
Consumers are urged to review bag labels for phosphorus content when shopping for fertilizer. Fertilizer labels have three bold numbers. The number in the middle is the percentage of phosphorus in the product, such as: 22-0-15. The law requires retailers to display phosphorus fertilizer separately from phosphorus-free fertilizer and post signs notifying customers of the terms of the law.
The law doesn’t affect agricultural fertilizer or fertilizer for gardens.
