You can do this by increasing soil organic matter, with mulches and the like, or by adding calcium and magnesium rich material like crushed dolostone. Preferably both. And then you wait. The physical route involves altering a section with coarser sediment like sand and silt or any low-clay soil.

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. 🕑 Reading time: 1 minute Groundwater is an important natural resource.

Soil horizons are different layers of soil with depth. The most weathering occurs in the top layer. This layer is most exposed to weather! It is where fresh water comes into contact with the soil. Each layer lower is weathered just a little bit less than the layer above.

Calcretes occur in a variety of morphologies that have been interpreted to represent stages of calcrete formation. One of the earliest and most internationally used evolutionary models is that of Netterberg (1969) who identified six fundamental types (forms) of calcrete: calcified soil, powder calcrete, nodular calcrete, honeycomb calcrete, hardpan calcrete, and boulder calcrete.

Corn is an annual with fairly shallow roots so ripping a foot or so deep is fine. Around here there are many thousands of acres of orchards (almond, walnut, pistachio, plum, mandarin orange, olive) that require ripping down to 3-4 feet to break up the hardpan so the tree roots can get established.
