What does high compaction in soil reduce?

High compaction in soil primarily reduces air circulation. Compacted soil has densely packed particles that create smaller pore spaces, limiting the movement of air within the soil. The reduced air circulation negatively impacts soil health by restricting the availability of oxygen to plant roots and beneficial microorganisms essential for processes like decomposition and nutrient availability. This lack of oxygen can hinder root growth and reduce the overall vitality of plants.

While high compaction can also affect water retention and nutrient absorption, the most direct and immediate consequence of compaction is the reduction of air circulation within the soil structure. Proper airflow is crucial for maintaining a healthy soil ecosystem, supporting plant development and optimizing growth conditions.
