A post on the City of Nixa Facebook Page states that their wastewater department is providing a free service to help farmland; the post can be read below.
"The Nixa wastewater department is looking for land application sites for biosolids. We provide land application of biosolids as a free service. This can help reduce how much phosphorus fertilizer is needed for farmland and can provide some moisture in the later summer months. If you have land and are interested in biosolids for your fields, please contact the Nixa Wastewater Department at 417-725-2353."
