abstract = {A soil coring protocol was developed to cooptimize the
estimation of root length distribution (RLD) by depth and
detection offunctionally important variation in root system
architecture (RSA) of maize and bean. The
functional-structural modelOpenSimRoot was used to perform
in silico soil coring at six locations on three different
maize and bean RSA phenotypes.Results were compared to two
seasons of field soil coring and one trench. Two one-sided
T-test (TOST) analysis of in silico datasuggests a
between-row location 5 cm from plant base (location 3), best
estimates whole-plot RLD/D of deep, intermediate, andshallow
RSA phenotypes, for both maize and bean. Quadratic
discriminant analysis indicates location 3 has $~70\%$
categorizationaccuracy for bean, while an in-row location
next to the plant base (location 6) has $~85\%$
categorization accuracy in maize.Analysis of field data
suggests the more representative sampling locations vary by
year and species. In silico and field studiessuggest
location 3 is most robust, although variation is significant
among seasons, among replications within a field season,
andamong field soil coring, trench, and simulations. We
propose that the characterization of the RLD profile as a
dynamic rhizocanopy effectively describes how the RLD
profile arises from interactions among an individual plant,
its neighbors, and thepedosphere.},
