Studies conducted by the Cranbury Environmental Commission have documented that storm-water runoff results in the flushing of certain pollutants, including phosphorus, into Brainerd Lake and the Cranbury Brook. Township residents are urged to help reduce the flow of pollutants into our water bodies. One way is to minimize the application of fertilizer on lawns and gardens. Over-fertilizing of lawns promotes runoff of phosphorus and other pollutants during wet weather.

To help reduce overfertilization of lawns, the Environmental Commission is making soil-testing kits available at no charge to Township residents. Soil testing can determine whether a lawn needs to be fertilized. The prepaid kits can be used to submit a sample of soil from your lawn to the Soil Testing Laboratory at Rutgers University (www.rce.rutgers.edu/soiltestinglab). The lab will test the sample (Level 1 Fertility Test) and provide recommendations for applying fertilizer or lime. Applying fertlilizer only when needed can save money and reduce the flushing of phosphorus and other pollutants into streams during wet weather.
