The GeoTech PRH one-shank subsoiler is a robust machine that, once attached to the tractor via the three-point hitch, allows for subsoiling (or scarification) of the soil. Subsoiling is a procedure that breaks up compact layers of soil, whether shallow or deep. This process is often alternated with tilling, which, unlike subsoiling, does not invert the soil but instead breaks up clods.

This method offers several advantages. First, it provides significant time savings, cutting the time needed to prepare the soil in half compared to tilling. Additionally, it helps preserve the organic matter and microorganisms in the soil. The technique also creates more space for roots, which enhances root growth. Another benefit is the improvement in drainage capacity, allowing water to flow more freely through the soil. Furthermore, it enhances permeability and aeration, contributing to healthier soil. Finally, unlike plowing, subsoiling does not leave a compaction layer beneath the surface, which is crucial for maintaining soil health.
