Long Island Agronomic Plan
The Long Island Nitrogen Action Plan (LINAP) is a multiyear effort to make meaningful reductions in nitrogen levels. LINAP is a collaboration between the DEC, the Long Island Regional Planning Council (LIRPC), and Suffolk and Nassau counties, with input from multiple partners and stakeholders.
LINAP has identified fertilizer as the second leading source of nitrogen contamination of Long Island waters, and their Fertilizer Management Workgroup’s recommendations try to balance residents’ desire for a healthy lawn with the need to significantly reduce nitrogen loads to Long Island’s waterbodies.
The following program meets the requirements recommended by LINAP in their “Recommendations for Fertilizer Nitrogen Applications on Residential and Commercial Turfgrass” https://www.dec.ny.gov/docs/water_pdf/linapfertilizer.pdf
