ISU Extension and Outreach University of New Hampshire fact sheets ‘Hay and Haylage Production with Selected Forage Species’, and ‘Pasture Production with Selected Forage Recommended Hay and Pasture Forages for Michigan . The more efficient seed placement provided by a no-till drill allows many of our more productive perennial forage grasses to also be successfully established by interseeding. Many restoration projects are completed in the summer and require fall seeding. This is an eOrganic article and was reviewed for compliance with National Organic Program regulations by members of the eOrganic community. A seeding delay into late spring to improve growing conditions often also leads to a greater competition from the existing grass sod. of N per acre should be applied in mid-winter to increase winter and spring forage production. If it is feasible to harvest the spring growth as hay, this is another option for allowing plants to develop a sufficient root system before grazing.
