Abstract
This study aimed to examine the effect of bio-energy byproducts (BEB) when applied
directly or indirectly through manure production on crop yield. It consisted of three field
experiments. The first experiment investigated the effect of manure derived from wet
distillers grain compared to barley manure on wheat yield, the second experiment
investigated the effect of thin stillage versus urea application on wheat yield, and the
third investigated the effect of wet distillers grain, biochar applied alone or combined
with urea, and glycerol applied alone or combined with urea on canola yield. Yields with
WDG-fed versus barley-fed cattle manure were similar, in line with similar composition
that was found for the two manure sources. Per unit of N added, the thin stillage produced
equivalent or higher yields than urea. This is explained by other nutrients in thin stillage,
including phosphorus, that would contribute to plant nutrition and yield. Pure or high
carbon content amendments (GL, BC) had limited effect on yield when applied alone.
Bio-energy processing byproducts can be effective amendments to provide carbon and
nutrients to the soil and plants.
