The Madison Metropolitan Sewerage District (MMSD) treats approximately 40 million gallons of wastewater daily from the City of Madison and the surrounding communities. As a result of the treatment, biosolids are generated and applied yearly to about 4500-5000 acres of agricultural cropland through its MetroGro landspreading program. The program has been very successful, but with urban pressure consuming cropland and phosphorus management issues potentially limiting application sites, the MMSD has decided to pursue other alternatives for the management of its solids. This research examines the development of a soil-like material (named MetroMix) for use in horticultural and nursery industry, turf uses such as golf course topdressing and turfgrass establishment, and home horticultural applications. The material is prepared with MMSD solids and locally derived sand and sawdust. Preliminary testing determined two promising combinations of various proportions of biosolid, sand, and sawdust. Those two mixes are being evaluated in an ongoing field study, where they were applied in spring of 2006 at four different rates, and two grass varieties (Kentucky Blue Grass and Creeping Bent Grass) are being grown on those plots. The MetroMix is being evaluated based on field assessments (stand verdure and density), the analysis of grass clippings collected during the growing season for dry matter yield and clipping N concentration and uptake, and the effect on soil physical properties. Preliminary results show statistically significant differences in dry matter yield, stand verdure, and stand density between plots treated with MetroMix and the controls that were fertilized with N fertilizer. The effect of the MetroMix on soil physical properties is currently being determined. Further results and conclusions are pending. The study is schedule to conclude in early 2007.
