a CON, manure from cattle on a control diet of barley; DDG, manure from cattle fed dried distillers grains and solubles; CON C&D, manure from the control diet cattle amended with construction and demolition waste. Mean ± standard deviation (n = 3) is shown for compost. Means with different lowercase letters are significantly different from one another (P<0.05).
b Samples were taken at the top (7 cm) and middle (90 cm) of each compost bin.
