Urban Fertilizer Management

Turf covers nearly 4 million acres in the Chesapeake Bay, or just under ten percent of total watershed area (CSN, 2009). Surveys have indicated that perhaps as much 50% of the turf cover is regularly fertilized (CSN, 2009). So it makes sense that better urban fertilizer management practices can prevent pollutants from getting into the waterways in the first place.

The Chesapeake Bay Program recently hosted an ‘Expert Panel’ to determine the amount of credit that should be awarded for the use of Urban Nutrient Management as a stormwater management practice. The Panel recommendations were finalized and accepted in March 2013 and can be accessed below and on our website here.
