A Beneficial Reuse of Biosolids

This rich compost made with biosolids is an excellent soil amendment for landscaping and gardens. Biosolids are a nutrient-rich, organic* byproduct of the wastewater treatment process that containplant macronutrients like nitrogen, phosphorus, and potassium, as well as supplementary nutrients such as sulfur, magnesium, calcium, copper, and zinc. 

Our WaterSmart Compost, made with biosolids and green waste is an excellent amendment for landscaping and gardening, closing the recycling loop locally and sustainably. 

Using WaterSmart Compost as a Soil Amendment

WaterSmart Compost is a beneficial, sustainable resource that can be used to improve soil quality and as a fertilizer replacement for crops. Most of the nitrogen in biosolids is organic*, acting as a slow-release fertilizer providing nitrogen when the plants need it, rather than all at once. It can reduce the use of expensive (often petroleum based) commercial fertilizers, and that means less environmental impact from fertilizer run-off into waterways.

*Organic material is derived from a living organism. Biosolids are not certified organic under the USDA’s National Organic Standards.
