Red clover is considered a short-lived legume, but new modern varieties are productive for three full seasons after establishment. Under what circumstances can they become a problem? Genevieve provides forage and cover crop research and marketing support for King's AgriSeeds Inc. in Lancaster County, PA. She has also worked on organic vegetable farms and as an intern in agricultural field trials at the Rodale Institute. Red Clover (Trifolium pratense) Red clover is a short-lived perennial with an upright growth habit that may be used as pasture or as a hay crop. One word of caution: moldy sweet clover often has high levels of dicoumeral (i.e., warfarin, rat poison), which is a vitamin K antagonist and ultimately can lead to internal bleeding and death. Red clover is the most popular forage crop to reseed – by far. You will need to suppress the grass until the clover becomes established.

One review suggest that clover grown under nutrient stress can have higher levels of formononetin (the main phytoestrogen of concern in red clover). Plant into a well-prepared, firm seedbed, up to ¼ inch deep. Five hundred dollars is a lot of money! It can be good to graze it in early spring, since the red clover is high in magnesium and complements lush spring grasses that can have a deficiency and lead to grass tetany. Some livestock producers have tried to feed red clover seed to their ruminant livestock in hopes that it would pass through the digestive tract and establish by feces deposition. The PREVAL MEADOW FESCUE in this blend is an improved variety that has excellent palatability and digestibility.Preval is high yielding with good regrowth. Seed is broadcast on pastures or hay fields which have been grazed or mowed short. animal stress: animals that are stressed because of management issues are more prone to succumb to secondary influences that otherwise would probably not be a problem. Clover root weevil remains a pest of white clover throughout NZ, particularly in Northland where the biocontrol wasp hasn’t established. Other researchers have found no adverse impacts. Anything you can do to correct these problems will enhance the establishment and longevity of your legumes. Red clovers remain productive later into the summer, however. Wow! At ground level, it is an excellent way to supply your grasses with some N (replacing on average 60 lb/A of N) and red clover is one of the easiest legumes to do this with. Once established, your stand should be fertilized with N if red clover makes up less than 30 percent of the grass-clover stand. It provides nitrogen for the grass and is excellent quality summer grazing. While these pastures provide good quality forage over a long portion of the year, they can be improved. Red clover can be grazed at pre-bloom to early bloom, about a 30-35 day interval, depending on the time of year. Red clover seed is less costly than alfalfa, but Undersander recommends using the hardiest varieties when establishing a new stand. Regarding seeding methods: whatever your particular approach, you can increase your odds of success by keeping in mind, matching the species you choose to your own farming context. Nitrogen will not kill clovers, but it stimulates grass growth and increases the potential of the clover being shaded out by the grass. Yes, apparently some people even seek milk from cows fed red clover. Early flowering red clover types include common medium red clover, suitable for 2-3 hay cuttings per year. Bradley knows cows prefer to graze clean grass versus a weedy mixed pasture. Clovers can be planted alone or in mixtures for numerous reasons: they produce an abundant crop, fix nitrogen, and grow in a wide range of soils and climates. Be sure to get the best information you can about varieties. Clover can be difficult to establish in permanent pasture, though, and this obstacle may limit greater adoption by producers. In a second study, cattle were fed red clover hay at 15 and 30% of the diet, normalized for protein. Generally, they are good ones to get rid of. What about the impact of red clover on swine reproduction? Red clover is tolerant of a wider range of soils than alfalfa – including some heavier soils with lower pH conditions – and the small seed broadcasts easily. Yes, but it seems to be extraordinarily rare, and I am not aware of any instances of this being formally documented in the U.S. I have never seen data that describes the extent to which this impacts total N fixation rates or overall pasture productivity. Due to a long-growing season, red clover typically is the highest yielding clover in areas of adaptation. Sweet clover is often used in wheat systems where frost-seeding is carried out. The majority of cattle in Tennessee graze tall fescue or orchardgrass pastures. Seeding three to six pounds of red clover every one to three years is a common practice to maintain a robust red clover stand. Scary. From http://vernon.edu. Pasture: 1 … Avoid using ryegrasses on sandy soil and soils with poor fertility. While he affirms the reality of the problem on subterranean clover in Australia, he has never seen it in the Eastern U.S. That said, the bacteria clovers need for N-fixation are probably already in most soils in VT.  Theoretically, over the years rhizobia can become less ‘effective’ at fixing nitrogen. Thanks to Genevieve of Kings Agriseeds for helping us out with this! Grazing pre-bloom won’t hurt the clover. It seems to me that this is where human psychology comes in. Newer varieties that have been selectively bred to have low levels of phytoestrogens cause little or no reproductive disturbance. Clover is a common weed in horse pastures. Associated with high levels of N fixation. The plant tissue tends to contain less lignin, making it more digestible. The benefits of establishing clover in grass pasture are well-known. Look for varieties that are resistant to northern and southern anthracnose, powdery mildew, and root and crown rots. Does Red Clover Cause Infertility in Sheep?

Whether you buy your seed pre-inoculated or purchase a liquid or peat-based inoculant from your seed dealer, it is a good idea to inoculte. Agronomically, mixes are always stronger than monocultures, and allow other species to persist and spread (depending on the species) as the clover thins. Defined as the edible parts of plants, other than separated grain, that provide feed for grazing animals or that can be harvested for feeding (Allen et al. For the sake of simple calculations, let’s say that the cost of VNS seed is about $2/lb, and the cost of a named variety is about $3/lb. If you want to keep up with all the other things Dan Hudson is doing, check out his blog: http://agronomator.wordpress.com, NEXT ARTICLE →Take the Drudgery Out of Soil Testing. He’s … We do not grow subterranean clover in the Northeastern United States. Leave your animals on lousy pasture all night – make sure they are good and hungry the next morning. Time of year: Australian research suggests that formononetin levels in red clover are higher in the spring and taper off after flowering. Because red clover tolerates more shade, it works well with grasses for pasture mix. It also is considered one of the most efficient legumes in nitrogen fixation from the air. Some researchers in the U.K. and Australia have documented impacts of red clover on ewe reproduction. Many other grass species can also work using non-conventional establishment methods, but success will be generally be lower than with the ryegrasses. Broadcast rates for the two clovers are 5 and 10 to 15 lbs/acre, respectively. It is very drought tolerant, but prefers soils with a more neutral pH. Vasodilation and ADG improved at both levels. The going rate is $10 per acre. In the spring when early grass growth begins, you can graze or clip it back (flash grazing to reduce competition from other species works well). Cattle Master Hay / Pasture This excellent blend of grass is easy to dry and ideal to mix with Clover and Alfalfa. It is not as drought-tolerant or easy to dry as alfalfa, however. While variety not state (VNS) clover can be just fine, you have NO IDEA what you are getting. Fescue-medium red clover Medium red clover has many advantages as a companion legume with fescue. Most of the time in this region, sweet clover is a part of a diversity of grasses, sedges, legumes and forbs on rangeland or pasture and doesn’t result in bloat. It is best to grow red clover in combination with a grass. Clover Seed varieties are also commonly used in agricultural cover crop applications to sweeten the … White, red, berseem, balansa and crimson clovers are safe additions to any pasture or hayfield, but the closely related alsike clover has been connected to health problems in livestock. Either that or they run out of money. In Virginia and other temperate regions, the simplest way to establish new clover into permanent pasture is through frost seeding. Since this is a contact killer, it must be done after grass breaks dormancy in spring green-up, when it’s actively growing. The most important take away from the no-till seeding trial was that hayfields and pastures can be economically rejuvenated using no-till seedings. If it has happened ever, it is probably the result of some combination of the following factors: Chemical structure of formononetin. Subterranean clover From: calphotos.berkley.edu.

This is long, but there have been a lot of great questions on this topic, and I wanted to address them sooner than later because the frost seeding window will probably be very narrow this year. Red clover Fescue If you want to see a full review of the literature on the subject go to: A review of the effect of legumes on ewe and cow fertility. In the cattle used in these studies they found increased vasodilation and a one-pound improvement in average daily gain (ADG). The conclusion of the paper is that more work needs to be done. The clover provides competition for more desirable grasses, and can even choke out the grasses you are trying to grow. The total cost of the VNS seed: $1,000; and the named variety: $1,500. Seeding rate for drilling is 3 to 5 lbs/acre for ladino and 8 to 10 lbs/acre for red clover. Use higher seeding rates of the clover to compete with the grass. One theory is that because ‘clover disease’ exists, it can be a convenient scapegoat for reproductive problems that are more likely related to other husbandry problems occurring on the farm. Absolutely! There has been almost no research done on this subject in the U.S.  See:Sheep Infertility from Pasture Legumes (Australia). Soil pH should be above 6. Add to that the cold, rainy conditions persisting in Missouri, and the condition is set for a bloat season. Avoid fertilizing with N, which will stimulate competitive grass growth. If frost seeding in late winter, you can use a disk or field cultivator to disturb the sod first, reducing grass competition and leaving more soil exposed for the clover seed to come into contact with.

My understanding is that if you have 50% grass or more, it is very rare. Bloat is the result of the formation of a stable foam in the rumen that ultimately prevents eructation (belching). What has practical experience suggested? The yield potential of red clover is excellent and red clover varieties can have higher forage yields than alfalfa. White clover is not as quick to establish, but because it spreads by stolons, what might look like a poor seedling density can turn into a great stand of white clover over a year or two. proportion: if you feed you animals only one species of plant (or even sometimes if you are heavily skewed in toward one species), your animals are more likely to develop any theoretical problems associated with that species.
