Soybeans grown in Canada are typically grown as part of a crop rotation (corn-soybeans-wheat).
There are a number of benefits to growing crops in rotation, such as:
- Reducing disease, pest and weed pressure
- Protecting against erosion and building soil structure
- Good crop rotations will provide consistent yields
- Increased profit potential for producers
In addition, many growers also use no-till or minimum tillage in their operations. In Canada, approximately 55 percent of soybeans are no-tilled. An additional 15-20 percent is minimum tilled. Minimal tillage and no-till management practices are helpful in promoting soil health. These management practices reduce erosion and increase organic matter and the presence of earth worms.
Another advantage of soybeans is that similar to legumes. Soybeans can “fix” the nitrogen they need from the air. Microbes that colonize the roots of the soybean plant take nitrogen from the air and convert it into a form the soybean can use to grow. This means that soybeans require little in the way of purchased nitrogen fertilizers, which is advantageous to producers.
