The dry conditions in parts of the state in 2022 put extra stress on pastures. Consequently, some pastures may have been grazed shorter than cattlemen would have liked. Additionally, nitrogen prices continue to rise as well as all costs associated with pasture management. As we head into the 2023 growing season, here are some considerations to help improve over-grazed and thin pastures, boost forage production, and help to manage pasture management costs.

For pasture stands that are on the thinner side, frost seeding or interseeding this spring can help to thicken stands up and be a longer-term solution to increase productivity. Now, not every pasture is ready for frost seeding or interseeding as its important to consider things like previous herbicide use, soil fertility and soil pH. Taking the time to properly plan and prepare will help with the success, and this ICM Blog “Still Time to Start Prepping for Pasture Renovations in 2021” addresses in more detail what should be done prior to any frost seeding or interseeding.
Early March can be a great time for frost seeding, whereas if you are planning on interseeding, that is typically done sometime between mid-March and early May. Read more on frost seeding and interseeding in the ICM Blog “Frost Seeding and Interseeding Considerations for Pastures This Spring.”
