Abstrakt: In irrigated areas where a “plowsole” layer existed, a large percentage of plant roots were found to occupy the first foot of soil and especially the first 6 inches. The number and size distribution of roots per increment of soil depth gave a better comparison between different crops from the standpoint of soil physical properties than a comparison of root weights alone.
