Figures
- Figure 1.
Mean (A) fine root diameter, (B), root mass density, and (C) root surface area density in soil cores removed from areas treated with and without a liquid soil amendment. Roots less than 2 mm (0.08 in) in diameter were surveyed. Bars represent one standard error. n = 20 for each treatment group. *P < 0.1; **P < 0.5.
- Figure 2.
Percent of fine root length in each of 19 diameter classes, from less than 0.1 mm to 1.9 to 2 mm (0.076 to 0.08 in). Fine roots (less than 2 mm [0.08 in] in diameter) were obtained from soil cores removed from areas treated with and without a liquid soil amendment. n = 20 for each treatment group. *P < 0.05.
