Subsoiling is an essential operation within long-term soil management to ensure a good soil structure, root growth and increased yield stability.
Visible strips showing erratic emergence of the germinating seed are a common problem. Often this is the consequence of over-compacted subsoil at the headlands and/or in the tramlines caused by the use of heavy implements or working on waterlogged soil. The roots of the crop cannot penetrate compacted zones. This leads to an insufficient supply of water and nutrients resulting in significant loss in yield. Subsoiling breaks up compaction in the subsoil, restores the gaseous exchange capability, and is thus the first step towards successful germination and seed emergence.
