Crimp mulching is a no-till farming technique that uses a roller-crimper to crush, flatten and crimp cover crops to create a protective mulch mat over the soil. A roller-crimper is a wide cylindrical drum with blades attached to it in various patterns to press the crushed plant stems into the ground. This technique can be used effectively with a wide range of annual cover crops, such as cereal grains and legumes.
There are numerous benefits to crop crimping as a no-till and mulching service. When compared to mowing, crimping reduces the likelihood of the cover crop regrowth, because it effectively crushes the plant’s vascular tissue. Additionally, since the plant remains intact, it decomposes slower, proving to be more effective at weed control because of the uniform structure of the mulch mat. Furthermore, this technique conserves moisture in the soil, and saves it from degradation common with tilling practices.
Arnold’s Custom Seeding maintains a fleet of custom-built roller crimper machines that are more than capable of meeting your crop crimping needs. Our crews will come to your farm at the end of your cover crop’s growing cycle. Our team will ensure the rollers effectively terminate your crop, so that an effective mulch mat is created. We can outfit our crimping equipment so that the roller is in the front, and a seed hopper is in the back to plant the next crop simultaneously with the crimping pass.
