The effect of the interaction between sample depth and profile design on root density of C. maculata (backtransformed means).
Sample depth (mm) | Root density (cm cm−3)z | |
---|---|---|
Layered profiles | Uniform profiles | |
0–150 | 2.5a | 2.2a |
180–330 | 1.6b | 2.4a |
350–500 | 0.9c | 2.7a |
↵z Trees planted in August 2000; the experiment concluded in January 2001. Means are from three replications.
y Means in the table followed by the same letter are not significantly different (P < 0.05).
