Medium Red Clover – Cover Crop April 1, 2011 by SoilGuide Leave a Comment If you are faced with depleted soil and have a season or two to enrich the soil before your desired planing, one of the best cover crops or green manures to introduce to your property is medium red clover. Greene, J.M. Decreased weed pressure, especially in spring and fall 4. Nitrogen credit for succeeding crops (average of at least 30 to 60 lbs/A for fall-planted, spring-killed stands in Michigan) 2. The effects of enhanced crude protein content of the animal diet provided by the inclusion of clovers in a grass-clover grazed pasture are well known. Addition of spring oats is an almost always a must when seeding clovers to ensure excellent winter survival of the clover. The clover is not hardy in the Northern part and does not bloom earlier like most other clovers. The change in emphasis of the USDA-ARS program at Mississippi during the 1990s resulted in a significant reduction in research with white clover in the region. Many confuse red clover with crimson clover, which produces red/crimson flowers. They are quick to establish producing high quality forage. Exp. This paper will attempt to summarize the current status of cultivars and cultivar improvement efforts in the USA Southern Region and discuss some of the factors contributing to the current status. Reports include: red clover – 77 to 260 kg N ha-1 yr-1 (Heichel et al., 1985) and white clover 62 to 332 kg N ha-1 yr-1 (Crush, 1987). Agron. Quesenberry. Baltensperger, D.D., C.E. Prine, O.C. Clovers have economic value in production agriculture primarily in three forms: 1) biological nitrogen fixed by well nodulated clover species; (2) high quality clover hay for sale (or on-farm use); and (3) increased beef production per animal unit resulting from improved protein content in diets of animals grazing clovers. Lechtenberg, and W.H. Increased soil organic matter and decreased soil erosion and surface water pollution 3. MSU is an affirmative-action, equal-opportunity employer, committed to achieving excellence through a diverse workforce and inclusive culture that encourages all people to reach their full potential. Crimson seed should be planted at a depth of 0.25- to 0.5-inch. Productivity and quality of annual and perennial clover-tall fescue mixtures. The problem with the clovers appears to be that of identifying a company that has good seed production and processing capabilities in the Pacific Northwest and a strong and diverse sales, advertising and marketing organization in the Southeast. Clovers in the Southeast USA: Why the Reduction in Use? Crimson clover is an excellent producer of nitrogen and there are some newer varieties on the market that are very winterhardy even into Michigan.Dr. Crimson clover is a real jewel among the cover crop species. 1987. cover crops, rather than the large-seeded varieties grown primarily as a food crop. A new cultivar, developed at Florida and tested as FLMR7, has enhanced resistance to RKN, and was recently approved for release by the Florida agricultural Experiment Station. 1980. P. 217-226. Dordrecht, Netherlands. As economic conditions change and the price of commercial N fertilizer increases proportional to the rising price of crude oil, the use of clovers may warrant review and reconsideration. The focus will be on the two major perennial clover species, red (T. pratense L.) and white (T. repens L.) clover, with some attention to crimson (T. incarnatum L.), and less emphasis on arrowleaf (T. vesiculosum Savi. White Clover. Crimson leaves have a more rounded tip and both stem and leaves have more hair than red clover. For example, the cultivar ‘Marathon’, bred at Madison, Wisconsin (Smith, 1994) is generally among the poorest yielding when grown at Gainesville, Florida. It forms tap roots and is useful for remediation of compacted soils. Performance and economic returns of beef cows and calves grazing grass-legume herbage. The intermediate types are typical of many pasture ecotypes with abundant flowering in spring, shorter growth habit, and a higher stolon density than large types. Dunavin, W. R. Ocumpaugh, and P. Mislevy. For example, Osceola has been successfully grown in most white clover growing areas of the USA, well north of its latitude of development. Spring oats are very quick to establish and do an excellent job of suppressing weeds as the main cover crop becomes established. Buy clover seeds online, all with nationwide delivery. Also called incarnate clover because of their blood-red blooms, crimson clover has been used as a cover crop in the United States since the mid-1800s. Red clover is not only the most widely used clover as a cover crop, but it is also one of the most widely used as a cover. The clover is an annual bloom and you must plant it each year to enjoy the best yield. Sometimes the use of clover can be viewed as an increased cost with associated risk. This crop is well-adapted a wide range of soil types and conditions. New cultivars can flounder and fail for lack of either production or marketing. Southern Pasture & Forage Crop Improvement Conference. Miller, and C.J. Univ. The question then becomes, why aren’t producers utilizing these plants to a greater extent. Crimson plants have dark green leaves and grow to a height of 1-3 feet. Pederson, G.A., and G.E. The legume cover crop system used no commercial fertilizer, no insecticides and herbicides on only two occasions—once to-spot spray Canada thistles and once as a rescue treatment for soybeans. Clovers are rapid growing biennials or short-lived perennials. Assuming yields of 8,000 lbs acre-1 and a selling price of $160 ton-1 for good quality red clover hay, the value of hay if all the 10 million USA acres of red clover were harvested for hay could be as high as $6.4 billion. A. J. Prod. In a dry spring, kill the cover early to avoid water stress on the succeeding crop. Red clover is also good for weed suppression. 2000. Planning for cover crops after winter wheat. Reference to commercial products or trade names does not imply endorsement by MSU Extension or bias against those not mentioned. Steer performance on tall fescue pastures. It has been used for a cover crop as far North as northern Maine. J. As with all cover crops, killing time for crimson clover is determined by the planting date for the succeeding crop and/or soil moisture. Ball Clover. If sufficient growth occurs in the fall, frost-killed crimson provides many cover crop benefits, including protection against soil erosion and contributions to soil organic matter. Persistence of selected white clovers in closely grazed tall fescue and bermudagrass sods. 1991. The base germplasm for this selection program was a diverse collection of USA and European cultivars and local ecotypes including ‘Flame’ (Baltensperger, et al., 1987). is a medium red clover adapted to the central region of the United States. Crimson Clover Information. Registration of ‘Marathon” red clover. Selection for reduced winter dormancy response has improved the production potential of red clover in the lower south. Freedom! It is also evident that substantial research is available to document the value of clovers for various applications. Thus, crimson clover can be planted early in spring or fall for weed control, or overseeded in corn at second cultivation or in soybeans at leaf drop. Inoculate the seed with Rhizobium inoculant for true clovers when planting in a field in which a nodulated true clover has not been grown in the last three years. A wide range of clover species available developed specifically for cover crops including berseem clover, crimson, red, white, and Persian clover. For example, red clover is a 1991. A long term reseeding population was collected in north Florida in 2000 and 2001, and preliminary evaluations are underway to identify superior plants in this population for potential development of an improved cultivar. 1996. Forage legume breeeding and evaluation at Auburn University in the last 16 years. Heichel, G.H., D.K. Other extensive research has documented that inclusion of clover in the sward of endophyte infected fescue pastures will ameliorate the toxic effect of the ergovaline alkaloids produced by the endophyte (McMurphy, et al., 1990). Click for a hub of Extension resources related to the current COVID-19 situation. Cultivars from this research are moving toward commercial status and Dr. Bouton will provide more details in his presentation. Fla. Ag. N/A. As with many cover crops, crimson clover seed germinates better and requires lower seeding rates when drilled than when broadcast. Iowa State University Press, Ames IA. Dunavin, and P. Mislevy. Strasia. Recent white clover research at Florida has focused on selection for RKN resistance in an Osceola type. clover. The current low level of use of clovers would suggest that farmers in the southeast USA have determined that economics often favor alternatives to growing clovers. Crop Sci. to extend the production season from as early as January into late June or July in the southern parts of this region. 34:1125. 1995. In M.J. Barker and W.M. Along with detailed management information on the most commonly used species—including grasses, grains, brassicas and mustards, and legumes—Managing Cover Crops Profitably offers chapters on the role of cover crops in […] Kluwer Academic Publishers. Conversely, although Cherokee may yield well in the seeding year in Kentucky it does not go dormant in the fall early enough and may initiate regrowth too soon in the spring resulting in winter killing and poor yields in the second year. Both red and white clover are perennial legumes high in protein and fiber that are widely used as forage for animal grazing and pastures. Production response and economic returns from five pasture programs in north central Florida. In general, research has shown beef average daily gains on grass clover mixtures equivalent to those on grass alone fertilized with 120 to 150 lbs N acre-1 (Hoveland, et al., 1991). Crop Sci. Avoid using it on poorly drained soils, however, due to potential disease problems. Crimson clover does best in heavy, well-drained soils and is widely grown in North and Northwest Florida. Seed germination and seedling survival require cool, but not cold, night temperatures (less than 60"F) and sufficient soil moisture. Although some germplasm testing of arrowleaf clover has been conducted at several locations, only the program at Overton, TX has been actively engaged in breeding arrowleaf clover in recent years. Manure Slurry Seeding of Cover Crops. Red clover. This can be beneficial for weed control, but may be detrimental to small seeded vegetable crops that are direct sown within two weeks after cover crop kill. There are two principal types of white clover grown in commercial agriculture, intermediate types, sometimes called Dutch white clover, and the large types, sometimes called Ladino white clover or Ladino clover. Nelson (ed) Forages Volume 1: An introduction to grassland agriculture. Primary uses include hay, silage and soil improvement – due in part to an ability to grow in a great range of soils, climates and fix nitrogen. Crimson clover grows best in cool weather, so grow it as a spring or fall cover crop. Land preparation . From the perspective of the breeders that I talk to, a major point of potential failure of new cultivars occurs after release, ie. AgriLife Extension's online Bookstore offers educational information and resources related to our many areas of expertise and programming; from agriculture, horticulture, and natural resources to nutrition, wellness for families and youth, and much more. Worley. Red clover and crimson clover don’t look anything alike. Brink. Benefits to beef cattle accrue in both improved calving percentage (Koger, et al., 1970) and improved weight gain of growing calves (Petritz, et al., 1980). As an example, red clover was estimated to be planted on as much as 35 million acres in the period 1909 to 1920, but declined to around 15 million acres in 1957, and to an estimated 10 million acres in 1995 (Taylor and Quesenberry, 1996). While this may be more effort, red clover will usually stay palatable to animals for an extra month in the year when compared to white clover. 3:208-209. A primary yield advantage of ‘Cherokee’ [developed at Gainesville, FL (Quesenberry, et al., 1993)] at southern latitudes is increased early season yield due to reduced spring dormancy (earlier spring growth) compared to cultivars developed in Kentucky, Indiana, or Wisconsin. Red clover has a life cycle of 2-3 years, by which time you may want to rotate your crops anyway. Current prices of N in the form of NH4NO3 are in the range of $225 to 250 t-1 or about $0.34 to 0.38 lb-1 N. Assuming an intermediate level of N2-fixation of 150 lb acre-1 yr-1 and a cost of $0.35 lb-1 N, the value of N fixed annually by the estimated 10 million acres of red clover in the United States would be $525 million. In contrast to red clover, the dormancy response of white clover does not seem to be as great a factor in stand persistence, although, as previously mentioned, it does influence flowering density and subsequent reseeding potential. Vance, and K.I. 740. Topics: cover crop species selection for use in mixes, seeding rates Cover crops: mixes. For this reason, clover is an ideal candidate for cover crop programs in many situations. Red clover is a short-lived perennial that is winter hardy throughout Pennsylvania. Petritz, D.C., V.L. Estimates of the amount of N fixed by perennial clovers are in the range of 100 to 300 kg ha-1 yr-1. Major Annual Clovers: Who Is Doing What in the SE USA? Agric. Mosjidis, J. Agron. Crimson clover has taller flower stems, grows more quickly and has larger seeds than the more commonly used red clover. Research at Texas has focused on development of an early flowering white clover (replacement for La S-1). produced by the cover crop inhibit growth of other plants. No research is known to have been conducted with this species in the SE USA in recent years. For example, the value of a clover crop for biological N2-fixation to add N to the soil for a companion grass or in crop rotations for a grain crop, must be weighed against the use of commercial N fertilizer for these same purposes. Crush, J.R. 1987. Tips for Interseeding Cover Crops, University of Vermont Extension Cover crops: all. Nitrogen fixation. Hybrids of Georgia ecotypes and large (Ladino) types were the most persistent in both tall fescue and bermudagrass [Cynodon dactylon (L.) Pers.] In R.F. 1985. Although several southeast USA breeding programs with clovers have been closed in the past two decades, it is evident from the above review that elite cultivars of the most important species are still being developed. In the southeast USA [Zone B (Taylor and Smith, 1995)] successful operators have used red clover in combination with crimson clover (T. incarnatum L.) and annual ryegrass (Lolium multiflorum Lam.) 29:62-65.
