Building Soil Health: No-Till Corn into Alfalfa in Calumet County ๐
In 2025 Nick Dallmann no-till planted corn immediately after harvesting the first crop of alfalfa. While this may sound like a straightforward practice, itโs an excellent example of soil health principles in action. By planting corn without tilling, Nick minimizes soil disturbance, helping to preserve soil structure, organic matter, and microbial life. At the same time, this approach maximizes the presence of living roots in the soil, which support nutrient cycling, improve water infiltration, and feed beneficial soil organisms. ๐ช๐ฑ๐ง๐ชฑ๐
For those implementing this practice, careful attention is key. Farmers should monitor soil trench closures closely to ensure good seed-to-soil contact, which is critical for uniform germination. Additionally, farmers should keep an eye on pest pressures, because planting into living residue can sometimes create favorable conditions for certain insects or diseases. ๐ With careful management, no-till planting corn after alfalfa can be a powerful tool for building long-term soil health while maintaining productive crops. ๐ฝ
