Quick Answer
Yes, legumes can be interseeded into established hay fields to enhance soil fertility, increase forage quality, and promote biodiversity, but the timing and technique are crucial for success.
When to Intersede
Interseding legumes into established hay fields is best done in the fall or early spring when the existing hay is not actively growing. This allows the legume seeds to germinate and establish themselves before the hay crop resumes growth. A general rule of thumb is to seed legumes 4-6 weeks before the first cutting of hay in the spring or 6-8 weeks after the final cutting in the fall.
Techniques for Interseding
To intersede legumes, use a drill seeder or a no-till planter to sow seeds at the same depth and spacing as the existing hay crop. A drill seeder is ideal as it allows for precise seeding and minimal disruption to the existing hay. The seeding rate for legumes can vary depending on the species, but a general rule of thumb is to seed at 10-15 pounds per acre. It’s essential to choose a legume species that is compatible with the existing hay crop and soil type.
Management Considerations
After interseding legumes, it’s essential to manage the hay field to promote the growth and establishment of the legumes. This may involve adjusting the mowing height, frequency, and timing to allow the legumes to compete with the existing hay. Additionally, it’s crucial to monitor soil moisture and fertility levels to ensure the legumes are receiving adequate nutrients. By adopting these techniques and management practices, small-scale hay producers can benefit from the advantages of legume interseding while maintaining a productive and diverse hay field.
