| Abstract/Contents: | "Improving mineralizable N estimates from exceptional quality (EQ) biosolids products is important for making more reliable N recommendations to rehabilitate disturbed urban soils for vegetative production. The objectives of this study were to compare the N fertilizer equivalency method and several chemical (NH4-N, NO3-N, total N, and organic N) and biological (7 d anaerobic incubation [7-AI] and Solvita CO2 Burst) tests for quantifying plant available nitrogen (PAN) and organic N mineralization of EQ biosolids used to grow tall fescue (Schedonorus arundinaceus Schreb.) in a clayey urban degraded soil. The EQ biosolids were products of thermal hydrolysis plus anaerobic digestion (Blue Plains exceptional quality biosolids; BLOOM), blending of BLOOM with woody mulch (BM), blending of BLOOM with sand and sawdust (Blue Pains exceptional quality biosolids + sand + sawdust; BSS), composting (Livingston compost; LBC), and heat drying (OCB; OceanGro thermally dried). The EQ biosolids were applied at agronomic N rates, and the inorganic fertilizer was applied at four N rates in a field study. The N fertilizer equivalency method predicted considerably lower organic N mineralization than calculated for BM (7.1%), BSS (-12%), and LBC (4.6%). Treatments BLOOM, BM, and OCB had the highest 7-AI organic N mineralization. Correlations between tall fescue N uptake and soil N tests showed that soil NO3-N and 7-AI were the best indicators of biosolids N availability in our urban soil. However, the relatively low correlations between soil N indicators and tall fescue N uptake was likely due to low residual soil N, high soil clay content, and possible low microbial activity of the low organic matter-containing anthropogenic soil." |
