↵zAcer × freemanii ‘Celzam’ (Celebration Freeman maple, [n = 19]), Acer × freemanii ‘Morgan’ (‘Morgan’ Freeman maple, [n = 18]), Acer rubrum ‘Fairview Flame’ (Fairview Flame red maple, [n = 19]), and Acer rubrum, ‘Frank’s Red’ (Red Sunset red maple, [n = 16]), at the P ≤ 0.05 (Tukey’s honestly significant difference HSD).
↵yMeans followed by different letters indicate a significant difference between cultivars within each soil treatment (NC = non-compacted, C1 = compacted once, C2 = twice-compacted).
↵xMeans followed by different letters indicate a significant difference between cultivars within each pre-plant N treatments. Standard rate [H: 100 mg·L−1 or Low rate L: 25 mg·−1] . Means followed by different letters within parentheses indicate a significant difference between the soil treatments or the pre-plant N treatments for each cultivar.
