What does conservation tillage primarily aim to achieve?

Conservation tillage primarily aims to reduce soil erosion, which is crucial for maintaining soil health and preventing the loss of valuable topsoil. This practice minimizes the disturbance of soil from traditional tillage methods by leaving a significant amount of crop residue on the field. The remaining residue acts as a protective layer, reducing the impact of rainfall on the soil surface and helping to prevent runoff. By keeping the soil intact and covered, conservation tillage not only protects the soil structure but also promotes water infiltration and retention. This method is beneficial for sustainable agriculture as it enhances soil quality, supports biodiversity, and contributes to overall ecosystem health.
