All Natural Fertilizer
SoundGRO is a choice fertilizer product for your landscaped areas and vegetable gardens. SoundGRO contains nitrogen and other nutrients that are vital for plant growth.


SoundGRO has many benefits over regular chemical fertilizers:
  • Slow-release SoundGRO works over a longer period of time, decreasing the need for frequent fertilizing.
  • SoundGRO has a low salt index, so it can be applied even in the hottest, driest weather without risk of burning your plants.
  • SoundGRO's composition improves soil structure.    

Manufactured Locally
SoundGRO is a fertilizer product manufactured at the Chambers Creek Regional Wastewater Treatment Plant from solid residual by-products (biosolids) of the wastewater treatment process. SoundGRO meets the U.S. Environmental Protection Agency's (EPA) highest standards for biosolid safety and is classified as Class A 'Exceptional Quality' product.
