Abstract

Biosolids derived from treatment of animal manure or industrial effluents can be used on farms, but their fertilizer value must be assessed. A 3-yr field study was conducted on a clay soil in Quebec, Canada, to evaluate the effect of several biosolids on silage corn dry matter (DM) yield; N-use efficiency; and soil N, P, Cu, and Zn availability. Raw liquid swine (Sus scrofa) manure (LSM), biosolids from four swine manure treatments (aerobic digestion [AER], anaerobic digestion [DIG], filtration [FIL], anaerobic digestion followed by chemical flocculation [DIG+FLO]), combined papermill biosolids (CPB), de-inking paper biosolids (DPB), and mineral N fertilizer (MIN) were applied before corn planting at a targeted rate of 150 kg total N ha−1. The DIG and DIG+FLO biosolids resulted in silage corn DM yield, N accumulation, and early season soil N availability comparable to LSM with an N-use efficiency about 70% of that for MIN. The AER biosolid resulted in low DM yield with an N-use efficiency only 10% of that for MIN; FIL and CPB had an N-use efficiency almost 40% of that for MIN, whereas DPB caused a decline in DM yield compared to a no-N control. The LSM-derived biosolids increased availability of soil P (0.34 kg kg−1 excess P) and, to some extent, Cu and Zn. The CPB and DPB biosolids had little impact on soil P, but DPB markedly increased Zn availability. Manure-derived biosolids and CPB were satisfactory N sources for silage corn while manure-derived biosolids caused soil P enrichment when applied based on crop N requirement.
