Rapid and accurate methods of measuring root length density (RLD, cm root cm-3 soil) are needed for verifying growth predictions and assessing genotypic differences. The core-break technique, in which the number of roots visible at a broken cross section of a soil core is used to estimate rooting, was evaluated as a means of measuring RLD. Root systems of wheat, Triticum aestivum L., cotton, Gossypium hirsutum L., and sorghum, Sorghum bicolor (L.) Moench, were sampled and core-break root counts regressed on RLD measured in the same soil core. Linear relationships were obtained between counts and RLD for each crop on each day of sampling. Calibration equations were
