Good structure in the subsoil primarily improves what aspect of plants?

Good structure in the subsoil primarily improves root elongation, which is vital for overall plant health and development. When the subsoil has a well-structured composition, it allows roots to penetrate deeper and spread out more effectively. This deep root growth is essential for accessing water and nutrients that may be present further down in the soil profile, especially during dry periods when topsoil moisture might be limited.

Additionally, well-structured subsoil reduces compaction and enhances aeration, creating a more favorable environment for roots to grow. This can lead to stronger, healthier plants that have a better ability to withstand environmental stresses. Root elongation is directly linked to the overall vigor of plants, affecting their capacity for nutrient absorption and their resilience to pests and diseases.
