Agricultural land application of biosolids recycles nutrients and organic matter to the soil, however the effect of treatment process on nutrient availability requires further research for better nutrient management. This study examined the bioavailability of nitrogen (N) and phosphorus (P) in alkaline treated biosolids (TB) when amended into three different soils. Despite a 45% reduction in total N and P content during treatment, TB did not show reduced N or P availability compared with sewage sludge (SS). Results of a corn growth experiment and a soil incubation showed that TB amendment resulted in little mineralization and generally net immobilization of N, and 2% total P availability to corn from TB. Results suggest that TB are not a source of bioavailable N in the short-term, but can be used as a P amendment for corn. Nutrient management of agricultural land receiving these materials should focus on P added and liming properties.
