A field investigation of sewage sludge treatments on agricultural production areas at DeSoto National Wildlife Refuge

Metadata Updated: October 9, 2019

The Fish and Wildlife Service and the City of Omaha participated in a six year study (1985-1990) to evaluate the environmental impacts of sewage sludge, composted sewage sludge, and commercial fertilizer applications on refuge croplands and the refuge environment. Baseline chemical concentrations were determined for the study site soils, resident deer (livers), and pheasants (livers). Baseline information also was determined for the soil amendments, including sludge, composted sludge, and commercial fertilizer. Fourteen agricultural plots, comprising a total of 92.8 acres, were then treated for a period of six years with the different soil amendments. Six plots were treated with sludge, compost, and commercial fertilizer soil amendments every other year. Six plots were treated with sludge and compost amendments every year. Two plots received no soil treatments, acting as controls. Residue analyses for metals were then compared with data for the baseline year. Results indicate no major differences for any metal concentrations in any plot among the years tested (baseline (1985, 1987, 1989-90). Differences were found in soil fertility among the test plots. However, these differences were not reflected in the crop yields. Very few conclusions may be drawn from the crop yield data. It is likely that factors external to the controlled parameters were affecting productivity, most likely climatic.
