Root development and moisture extraction in a nitrogen-fertilized sandy soil exceeded that in unfertilized soil during early growth of the corn, but were essentially the same under both conditions at maturity. Fertilized corn was more efficient in its use of soil moisture. Restricted root development was associated with high bulk density and low nutrient availability in the substratum. Roots in unfertilized plots were associated almost exclusively with old root channels and organic materials.
