An Analysis of Soil Coring Strategies to Estimate Root Depth in Maize (Zea mays) and Common Bean (Phaseolus vulgaris)
Manhattan distances between Voronoi-adjusted RLD (cm cm-3) and estimated RLD (cm cm-3) from individual and combined soil coring locations for 2015 and 2016 field trials. Dots represent mean and bars represent standard deviation. The three combinations of coring locations with the lowest Manhattan distance are displayed for each category (combination of 2, 3, 4, and 5 core locations). Seven replications of each location by species combination were taken.
