Our Lawns and Algae/Harmful Algae Blooms

Nutrient Pollution starts locally! How do we contribute? Nutrients come from sediment and fertilizer runoff from our lawns, from directing car wash soap, pet waste, or leaf and grass clippings to the storm drain or local waterways, and from improperly-managed septic systems. Fertilizer can be particularly harmful! Most soils in NYS contain adequate amounts of Phosphorus. Please Look for the Zero when buying fertilizer, and only apply IF NEEDED..  Learn how to cultivate a sustainable lawn and also see our Sustainable Landscapes series on establishing a thicker lawn/turf, pest management, and more.
