| Sumario: | Excessive conventional tillage can degrade important aspects of soil quality and health over time. Strategic tillage offers a focused solution to address priority soil limitations with minimal disturbance. This chapter reviews the current science on how strategic tillage affects key soil physical, chemical, and biological factors relevant to soil function and crop yields. In contrast, strategic tillage involves the targeted, occasional, and shallow use of tillage equipment to address specific observed soil constraints without general field disruption. Potential advantages of strategic tillage discussed include improved soil structure, increased infiltration and rooting depth, better incorporation of amendments, disruption of compaction, enhanced soil biological activity and carbon storage, increased nutrient availability, and improved crop yields. To minimize disturbance and maintain soil function, strategic tillage should be integrated with other conservation practices like cover crops and crop rotation. Criteria for selecting appropriate tillage equipment and practices based on crop, soil, and climate factors are explored. Ongoing site-specific evaluation and refinement of strategic tillage practices using crop yields and soil analysis is emphasized. Despite needing more research, strategic tillage shows promise as a precise soil management approach that maximizes productivity and resilience while balancing periodic focused tillage with principles of soil health. |
