Randomized complete block design with three treatments and three replications. Treatment 1 (M+N): 6t/ha poultry manure plus 150 kg/ha N fertilizer; Treatment 2 (M+B): 3t/ha poultry manure plus 3 t/ha biochar; Treatment 3 (M+N+B): 3t/ha poultry manure, 3 t /ha biochar, 150 kg/ha N fertilizer in Bayfield, Huron County, Ontario in 2016.
