Pot experiments were conducted to compare the ability of maize, wheat, cotton and groundnut plants to overcome soil compaction restraints. An increase in mechanical resistance of the soil resulted in a decrease in root length or rooting density for all the plants (the decrease in rooting density was calculated relative to a maximum obtained in loose unrestricted soil with a penetrometer resistance of 0.3 to 0.5 MPa).
