No-till farming is widely recognized for conserving soil and water while lowering production costs. However, over time, challenges can develop in long-term no-till systems. These include the rise of herbicide-resistant weeds, soil compaction, and the uneven distribution of soil nutrients like carbon and phosphorus.
To address these concerns, Dr. Humberto Blanco, a soil expert from the University of Nebraska, shared his research findings during the June 2025 Soil Health Digital Café. His presentation focused on the role of strategic tillage—an occasional, carefully planned soil disturbance—within long-term no-till practices.
According to Dr. Blanco’s research, strategic tillage can be a helpful tool. It may break up compacted soil layers, making it easier for plant roots to grow. It can also help mix soil nutrients more evenly, which can support healthier crops. In addition, it has the potential to manage stubborn weeds that no longer respond to herbicides.
The research showed that when done properly, strategic tillage does not undo the benefits of long-term no-till systems. In fact, it can improve soil structure and water movement, helping to maintain soil carbon levels while improving crop yields.
This approach is not meant to replace no-till farming but to enhance it when problems arise. It should be used carefully and based on research and local field conditions.
Overall, strategic tillage may offer farmers a way to strengthen their no-till systems while preserving the soil’s health. Dr. Blanco’s insights remind us that sustainable agriculture can still adapt when challenges emerge, using science-based solutions to support long-term success.
