relative to the use of certain fertilizers on turf.

HB 1293 updates New Hampshire laws to regulate the sale and application of fertilizers specifically for urban lawns and turf. The bill establishes strict limits on nitrogen content, capping application rates at 0.7 pounds per 1,000 square feet per use, and defines specific categories for low-phosphate and no-phosphate products intended for new or established urban grass. It also introduces new definitions for terms like "enhanced efficiency fertilizer" and "plant biostimulant" to clarify what products fall under regulatory oversight. Although the governor initially vetoed the measure, the legislature overrode the veto, and the law is set to take effect on January 1, 2025.
