  • 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.
  • SoundGRO is safe for the environment and will not infiltrate groundwater or pollute rivers and lakes.

Manufactured LocallySoundGRO

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.

Using fertilizer manufactured from biosolids is a safe and effective way of 'closing the loop' and recycling our natural resources.

Individual bags of SoundGRO may be purchased through a number of local distributors. SoundGRO is also available in bulk quantities, including in 1-ton palletized bags (40-50 lb. bags) and in 1-ton totes. SoundGRO is not currently available in loose bulk. Orders will be filled as supply allows. To place a large-volume or commercial order, email us or call 253-798-3099.
