Vertisols: Usually mollic epipedon; high in shrinking and swelling clays; >30% clay to a depth of 50 cm; deep cracks (called gilgai) form when soil dries; form from parent material high in clay (e.g., shales, basins, exposed Bt horizons of old soils); 2.4% of global and 1.7% of U.S. ice-free land.

Verify the depth z below the uniformly loaded area where the stress increase is to be obtained. Plot the plan of the loaded area with a scale of z equal to the unit length of the chart (AB). Place the plan on the influence chart in such a manner that the point below which the stress is to be determined in located at the center of the chart.
