Lawn fertilizers contain nutrients such as nitrogen and phosphorous that help your grass and plants grow. When these nutrients are applied in excess, they can run-off of leach into nearby streams and rivers.
Runoff is precipitation that does not evaporate or soak into the ground but flows across the land into waterways becoming a transporter of non-point source pollutants. There are several ways communities can help reduce runoff from impacting local waterways and ultimately the Chesapeake Bay
Planting trees is a fun and productive way to protect our local waters and the Chesapeake Bay from the impact of runoff by: promoting soil infiltration, slowing water down, absorbing water, binding of the soil, stabilizing stream banks, and filtering of pollutants.
