This winter’s erratic weather, swinging from –30°F wind chills to unseasonably warm temperatures in the 50s, has left many wanting spring and ready to get back in the fields. Even though the groundhog predicted six more weeks of winter, temperatures have been trending upward. Over the next week, highs are expected to stay above freezing during the day and drop below freezing at night. These natural freeze–thaw cycles signal the slow transition into spring.
These conditions open an opportunity to thicken forage stands through frost seeding. Frost seeding involves broadcasting or overseeding legumes into a thinning pasture or small grain stand.
