The New York State 2010 Dishwasher Detergent and Nutrient Runoff Law went into effect with the New Year, limiting the amount of phosphorus lawn care operators can use in fertilizers.
The restrictions will reduce the quantity of phosphorus entering the state’s waters, according to the New York State Department of Environmental Conservation’s Division of Water.
Beginning Jan. 1, these rules were put into effect:
- Use of phosphorus fertilizer on lawns or non-agricultural turf is restricted to when a new lawn is being established or when a soil test indicates additional phosphorus is needed.
- Application of any fertilizer to lawns or non-agricultural turf is prohibited between Dec. 1 and April 1.
- Application of any fertilizer on lawns or non-agricultural turf within 20 feet of a water body or on paved surfaces is restricted.
- Retailers must display phosphorus fertilizers separately from phosphorus-free fertilizer and must post signs notifying customers of the terms of the law.
