Notes:
Summary Four methods of measuring root distribution in a spring oat crop were compared: minirhizotrons installed vertically, minirhizotrons installed at an angle of 45°, core-break root counts and direct measurement of lengths of root washed from soil cores. Minirhizotrons gave better estimates of root distribution where installed at 45° rather than vertically and could be used in the horizon between 30 cm below the soil surface and the maximum depth of rooting. We confirmed that relative root distribution at a particular growth stage can be assessed from counts of the number of roots crossing horizontal faces in core segments.
