It can be slowly pushed into moist soil until a resistance point is reached. The resistance point will be the pan. The penetrometer can then be pushed until it abruptly breaks through. At this point, the bottom of the hardpan, or “breakthrough depth,” is reached and can be measured.This hardpan layer is a shale layer with low resistivity zone on 2-D tomograms. ...

Soil profiles are continually disrupted by the actions of flowing water, wind, or ice and by the force of gravity.These erosive processes remove soil particles from A horizons and expose subsurface horizons to weathering, resulting in the loss of humus, plant nutrients, and beneficial soil organisms.

Intrazonal soils have more or less well-defined soil profile characteristics that reflect the dominant influence of some resident factor of relief or parent material over the classic zonal effects of climate and vegetation. There are three major sub-types, two of which have two further sub-types each. Calcimorphic or calcareous soils develop from a limestone.The term hardpan is often used in the literature on soils. A hardpan soil horizon is defined as a hard (compacted) soil horizon. Hardpan is often composed of compacted and/or cemented clay with calcium carbonate, iron oxide, or silica. Hardpan horizons are nearly impermeable and, thus, restrict the downward movement of soil water. Otherwise go with a TTTF seed.
