Frost seeding offers several potential advantages when properly implemented. This can result in uneven seeding. Annual lespedeza can provide a drought-tolerant warm-season option in some areas. Freeze-thaw cycles then provide shallow coverage of the seed, which help shield from early spring rains. Frost seeding can be an effective, low-cost method to introduce new forage species into an existing sod or to maintain the species makeup of pastures. A large body of research has reported the relationship between temperature and growth in alfalfa Identifying Base Temperature for Alfalfa Germination: Implications for Frost Seeding Timing of seeding for new alfalfa establishment is critical to the success of the emerging crop and for the future success of the stand. Frost Seeding Red Clover in Iowa. Alfalfa is extremely cold tolerant at emergence and this can give a false sense of security, but as the plant develops to two trifoliate leaves, frost sensitivity becomes greater and it may be killed by exposure to 26°F for as little as 4 hours until it reaches the three trifoliate leaf stage. Broadcast seeding in late winter, or frost seeding, is a widely used strategy to bolster pasture productivity or add new species to the forage mix. Frost seeding legumes can be very successful when performed correctly using the best suited species. Overseeding, in particular, adds to the cost. Typical frost-seeding rates for both red and white clover range from 2 to 6 pounds per acre. What have you guys done in the past that has & has not worked? The use of certified seed of improved varieties coupled with good grazing and fertility management will ensure good establishment and production for years to come. The down side of alfalfa is a built in autotoxicity that allows existing alfalfa plants to kill any new germinating alfalfa seed. Over time, some farmers have learned planting alfalfa in the fall instead of the spring can make a significant difference in alfalfa yield and development the following year. Iowa State recommends broadcasting 10-15 lbs/ac onto frozen ground and the seeding method is likely going to be dictated by what equipment you have available. alfalfa will probably go dormant earlier than here and not be there much for hunting season unless you find some colder varieties.There may be better options.Lots of guys from up that way on deerhunterforum.com and allthingshabitat.com Grasses that have worked occasionally for frost seeding are the small seeded ryegrass or hulled orchard grass. Alfalfa should be frost-seeded on well drained soils with near neutral pH … See how we employ frost seeding to help fill in those perennials for lush, full food plots. The danger of freezing actually is greater after alfalfa reaches the third or fourth trifoliate leaf stage, or about 4 inches … Other legumes suited to frost seeding include white clover, birdsfoot trefoil and potentially alfalfa. These may include: establishment of forage in undisturbed sod, reduced labor, energy and cash expense compared to conventional tillage methods, the ability to establish forages with minimal equipment investment, and little, if any, “non-grazing” period. Then would it be possible to broadcast a brassica and oats blend in for a bigger fall attraction? If you feel strongly about having some alfalfa, you can include a little with the clover as you frost seed – 2-3 pounds/acre along with 3-4 pounds of clover – but know that you may not see the alfalfa. Frost seeding is an economical, effective way to improve the quality and quantity of pastures and is one of the most cost effective and energy efficient seeding methods. You should frost-seed in January or February to allow freezing and thawing to work the seed into the soil. Frost seeding is the process of broadcasting seed onto existing stands while the ground is still frozen with the purpose of thickening the stand or introducing new plant species. Grass species are much more difficult than legumes to frost seed successfully. Birdsfoot trefoil is another option and is often frost seeded in a mix with red clover. Frost seeding switch right before a snow is good,frost seeding alfalfa will probably work.I like to plant mine in late sept early oct in Kansas.In Wisc. Some clover species are also not appropriate for pastures and/or this early-season time frame. Small-seeded forages such as clovers do not spread as wide as people expect. tify when and where frost seeding alfalfa can be most effective. Frost seeding has proven to be an effective way to improve pasture quality and yield. Frost seeding. If there is existing alfalfa in a field, putting more alfalfa seed into the ground is counter productive. Very young alfalfa seedlings can tolerate temperatures maybe as low as 20 degrees. Additionally, if you decide to try alfalfa, don’t seed it into existing alfalfa (because of autotoxicity concerns). Red and white clovers are the most commonly used and establish well with frost seeding. Frost Seeding - posted in Alfalfa/Hay: Ok, it's getting to be that time of year when some of us are going to be thinking about frost seeding. According to Steve Orloff, extension educator with the University of California – Davis, the biggest advantage to a fall seeding is: It favors root growth over shoot growth. Some clover species are also not appropriate for pastures and/or this early-season time frame. Additionally, if you decide to try alfalfa, don’t seed it into existing alfalfa (it is autotoxic). Providing good seed-soil contact and limiting plant competition is key to frost seeding success. This is useful because legumes often do not persist as long as grasses when seeded together, and frost-seeding is an effective way to maintain the legume proportion without needing to re-establish the … Temperature is a critical component of most developmental pro - cesses in plants including germination. Freeze-thaw cycle needed Frost seeding is … Some wilting can be visible about 24 hours after frost or some yellowish or brownish discolouration 3 or 4 days later. The important thing is minimizing the risk with this risky seeding. Frost seeding by broadcasting forage seed on frozen ground is a simple, low cost method of improving the yield and quality of older, thinning, “run out” pastures. Alfalfa is extremely cold tolerant at emergence and this can give a false sense of security, but as the plant develops to two trifoliate leaves, frost sensitivity becomes greater and it may be killed by exposure to 26°F for as little as 4 hours until it reaches the three trifoliate leaf stage. Frost seeding is thought to be the simplest and least expensive method of seeding; however, it can also be inconsistent with a success rate of only about 60%. I have an alfalfa/timothy field that I seeded last spring that due to weather didn't turn out the best. Grasses that have worked occasionally for frost seeding are the small seeded ryegrass and orchard grass, or hulled orchard grass. Alfalfa came in real nice but no grass at all. Though not as reliable as seeding with a drill, frost seeding has still been proven as effective and budget friendly. Actually doing the seeding isn’t that tough. Frost seeding is an easy way to get legumes started in your pasture, grain field, or even in a declining stand of alfalfa. Seed Selection, Legumes: Alfalfa, clover, and trefoil can all be successfully frost seeded. Frost seeding alfalfa (Medicago sativa L.) can be convenient and economical for establishing or renovating forage stands; however, premature seedling emergence triggered by unusually warm temperatures followed by fatally cold temperatures can lead to seedling mortality and stand failure.
