Soil compaction is a serious problem due to the impact on the yields, while this is not often connected to compacted soil. Sometimes yield is being potentially reduced by as much as 10%, especially when it occurs under crop rows or ridges. Compacted soil prevents the roots from growing so there is not enough access to the nutrients that the plant needs. Preventing new compaction during tillage and fieldwork is therefore essential. Yield reduction can come from many factors, like too low organic matter, not enough water, diseases, etc. This makes it hard to conclude where the reduction is coming from. When a farm has a lot of heavy-tillage crops one can understand that those soils have a high change of soil compaction after harvesting, here comes the benefits of cover crops. There are also ways to loosen the compacted soil with certain machines.

Is this what I was looking for?
Founded in 1987 in South Australia, Kelly Tillage has become a global leader in shallow tillage equipment. Their signature product, the Kelly Tillage System, features a diamond-shaped frame equipped with various disc chains designed for ultra-shallow tillage operations. This system helps farmers manage crop residues, control weeds, and prepare seedbeds efficiently, all while conserving soil moisture and structure.
Key Features of the Kelly Tillage System
- Versatile Disc Chains: Options like the CL1, CL2, K4, and R300 cater to different soil types and farming needs, from heavy residue management to precise seedbed preparation.
- Shallow Tillage: Operating at depths of 2–5 cm, the system minimizes soil disturbance, promoting better soil health and reducing erosion risks.
- Cost Efficiency: By combining multiple field operations into a single pass, farmers can save on fuel, labor, and time.
- Sustainability: The system supports sustainable farming practices by enhancing soil organic matter and reducing reliance on chemical herbicides.
Compaction is tire pressure
One of the most overlooked causes of compaction is tire pressure. Heavier machinery with high tire pressure exerts more force per square centimeter, compressing the soil. Even one pass with improperly inflated tires can create compaction layers 30–50 cm deep.
