Broadcast the seed during the spring period (March or early April) when the snow cover has melted off but the soil surface is going through the daily freeze-thaw cycle. Overgrazed pastures or pastures with thin stand or bare spots tend to have the highest germination success due to the seed to soil contact and lack of competition from surrounding plants. 70% Climax Timothy 15% Alsike Clover 15% Wildcat Double Cut Red Clover . Often frost seeding is done to introduce or increase the stand of a forage legume species into an established grass stand; legumes typically have a higher success rate for establishment. Contact your local Extension office for any assistance. Other legumes and timothy can be frost seeded with slightly less success than clovers. Ingredients. Red Clover and Birdsfoot Trefoil make a good mix for seeding as Red clover often only produces for 2 years; once the Red Clover stand declines the Birdsfoot Trefoil is established enough to be the dominant legume. Below are the suggested seeding rates in pounds per acre. There are many resources available for those new to frost seeding. Iowa producer experience has been best when legume seed is broadcast on the thinnest, least vigorous pasture areas. Success has also been improved where the previous grass stand has been heavily grazed, thus, exposing more areas of bare soil. Frost seeding can be an efficient and cost effective way to reseed or introduce new forage species to pastures and hay meadows. This mixture may be planted with a small grain. If planted with a winter grain, the timothy is seeded with the grain in the fall, and the legume is planted early the following spring.

That's 2.56 million seeds per acre (90 acres) or 57 … Freeze-thaw cycles then provide shallow coverage of the seed, which help shield from early spring rains. While frost-seeding is the easiest and likely the least expensive pasture seeding approach, using a drill for more precise seed placement and seeding when soil conditions are more supportive of quick germination usually provide better and more uniform stand densities. Timothy is popular in the northern half of Pennsylvania and most of New York State because of its natural adaptation to moist, cool environments. Our recent cycles of warm weather and snow have been somewhat of a nuisance; however, for those of you with a thin stand of vegetation in your pasture or hay field, this weather may be a great aid in frost seeding these areas.

Same thing with clover in the pasture. Birdsfoot Trefoil is slower to establish than Red Clover; however, overtime trefoil stands improve. Red clover has been the most consistently successful forage species to establish using frost-seeding. Frost seeding will return legumes to the pastures; dividing the pasture into at least four paddocks will provide forages time to rest and regrow through the growing season.

Once you have seeded the pasture, the work isn’t completely over. Another good time is December, after all the growth has stopped for the year. Species such as reed canarygrass and timothy which have very small seeds are especially sensitive to seeding depth and seeding failures are usually a result of placing the seed too deep, especially with no-till seedings. The main advantage to frost seeding is the ability to establish desirable species into an undisturbed sod at a low per acre cost. Frost seeding should not be done when the ground is covered with snow as quickly melting snow causes the seed to wash away. Frost seeding is a popular option to improve forage yield and quality of pasture and hay land. Though no-till drilling has more guarantee of success, frost seeding is an easy operation while you have time in the off season, and if managed correctly and timed properly, has good likelihood of success. In general, the heavier the soil and the higher the moisture content, the shallower the seed should be placed. It is also important to use high-quality seed and the correct planting rate to guarantee a good stand. Rotationally grazing is the best way to improve a stand for the long term.
