Nitrogen-rich maize fields are undersown with grass

When your maize stops growing in late summer, you risk losing your nitrogen. That's when you need a well-established grass crop beneath the maize plants. Grass greatly reduces nitrogen loss. It can also help you meet your EU greening programme.

Tried-and-tested technique

Recent trials supported by DLF show that grass sown beneath maize helps maintain soil quality and nitrogen levels, with no loss of maize yield. The trials, which lasted three years, show that in Danish conditions three grass species – perennial ryegrass, cocksfoot, and tall fescue – grow well beneath maize without harming the main crop. The trials also identified the best time and method of seeding that produces the best outcome.
