Biosolids refer to the nutrient-rich organic materials produced by wastewater-treatment plants. In the past, the majority of this raw sewage was disposed of by dumping directly into our nation's rivers, lakes, and bays. However, upon treatment and processing, this sewage sludge, called Biosolids, can be safely recycled and applied as fertilizer.
Biosolids were used by American farmers since the 1920s who believed the material worked better than traditional fertilizers due to their rich nutrients and organic matter that reduced soil erosion. In southeastern Georgia, some farmers are using the biosolids under the regulation of the Georgia Department of Natural Resources. In AESL, we offer a variety of tests for Biosolids, sludge, and non-animal wastes, including minerals, nutrients (especially different forms of N), total carbon, total (volatile) solids, and environmental concerns (such as pollutants Hg and As, and fecal coliforms). Please refer to the full list of tests offered in AESL.
