Evaluation of a core sampling scheme to characterize root length density of maize
Plant and Soil, 2008Information about root distribution is important for characterization and modeling of water and nutrient uptake, biomass, and yield. Due to the heterogeneous distribution of roots in row crops, the reliability and representativeness of estimates of RL and root morphology using core sampling depend on the number of samples and their location.

Flexible- and rigid-walled minirhizotron techniques were compared for estimating root length density of 14- to 28-day-old Pinto bean (Phaseolus vulgaris L.) and spring whet (Triticum aestivum L.) plants in soil boxes under controlled environment conditions at three soil bulk densities (1.3, 1.5 and 1.7 g cm−3).

Root Length Density from Core-Break Observations: Sources of Error
1991ABSTRACT Sources of error in estimating root length/volume of soil from counts of roots visible at broken faces of a soil core were analyzed. Angular distribution of root growth has a large effect on the relationship. Systematic gradients of root length density in a core should have little influence on calibrations.
