What type of tillage would be used to break up compacted layers of soil?

Subsoiling is a specific type of tillage technique designed to address soil compaction, particularly in the deeper layers of the soil profile. This method utilizes a subsoiler, a specialized piece of equipment that penetrates the compacted layer without turning over the topsoil. By breaking up the compacted layers, subsoiling allows for improved water infiltration, better root penetration, and enhanced airflow within the soil, which are crucial for optimal plant growth and health.

The focus of subsoiling is on alleviating the effects of compaction that can hinder root development and water movement. This is particularly important in agricultural practices, where soil health is directly linked to crop yield and productivity. In contrast, other tillage methods such as mulch tillage, no-till, and ridge-till do not specifically target the deeper compacted layers of soil and primarily focus on other aspects of soil management, like conserving moisture or reducing erosion.
