Description
Photographs of soil pit faces are overlaid with 1×1 cm grids to systematically score presence or absence of fine and coarse roots in each grid cell, providing depth-resolved estimates of root spatial distribution.
Typical Equipment
- camera
- measuring tapes
- image analysis software
- computers
Output Measurements
- root presence-absence by depth
- fraction of soil area containing roots
