 Hardpan soil is clay-like and almost too hard to break down. It can persist and stay dense through different seasons. While rapid freezing and thawing can reduce the soil’s hardness, this isn’t the case with hardpan soils. Moreover, hardpan soil doesn’t allow root intrusion.

This soil layer is usually found beneath the topsoil. A distinctive feature that sets hardpan apart from other types of soil is its water-impervious nature.

Let’s learn the three most common ways to detect hardpan soils.

1.     Deep Tillage

If you notice a deep tillage issue in your yard, chances are that it contains hardpan soil.

While tillage is considered a solution for soil compaction problems, it can further strengthen the hardpan’s density. Deep tillage tends to remove the protective soil layer, making it vulnerable to erosion and weather damage.

You can use a penetrometer to check the depth of the hardpan soil and slowly push it further to ensure moisture retention and resistance.

2.     Resistance

The soil penetrometer is also effective for measuring soil resistance. This is another common way to determine hardpan soil by checking the surface’s density and compaction.

Results indicating 400 to 500 PSI mean that soil is substantially compact. Higher the reading, higher the chances of hardpan detection.

3.     Compaction

Compaction is a common indicator of hardpan soils. There are, however, different types of soil compaction. Soil crusting on the top surface indicates density and moisture trapped due to deep tillage and precipitation.

If you notice deeper crusting, it means that it is soil prairie instead of true hardpan.

Hardpan soil isn’t ideal for septic systems. They can lead to septic failures over time, thereby nullifying the effect of wastewater treatment. Hardpan soils can block the water passage and cause drain field leakages.

At West Wind Marketing, Inc., we strive to offer the best eco-friendly soil treatment and septic system products. Our Septic Perc® and Mega Bio™ products are two of the most effective drain field restoration and hardpan treatment products available in the US.

Septic Perc® opens up the compaction in hardpan soils and allows Mega-Bio™ to reduce biomat for drainage and leach field restoration. All in all, this powerful combination of Septic System Products enhances the functionality and useful life of septic systems.
