Technical Abstract: Subsoiling is a form of deep tillage performed to alleviate compaction. Numerous soil physical properties of compacted soils are improved including total porosity, aeration, water storage, infiltration and penetration resistance (soil strength). These changed properties promote greater root growth, allow better utilization of water and nutrients by crops and often result in increased yield and improved quality. This review article interprets the technical aspects of subsoiling for understanding by the general public and describes the complexity of soil and plant interactions that must be considered by farmers contemplating the use of this seemingly simple technology.
