Manure Slurry Seeding of Cover Crops. Therefore, there is less risk of not being able to establish other cover crops in a dry August. Berseem clover cover crops provide excellent nitrogen in soil. Unfortunately, many herbicide programs preclude successful establishment of red clover this way. Although classified as a perennial legume, it acts like a biennial and typically succumbs to disease pressure in its second growing year. Like all cover crops, crimson clover has specific management needs to ensure a good, reliable stand. What is berseem clover? Harvesting one cutting of red clover forage is possible in the fall in red clover that was established early in the year. Crimson clover (Trifolium incarnatum) is native to the Mediterranean region. No fertilizer needs to be applied to the clover in most cases. Freezing and thawing cycles will help improve seed-to-soil contact of red clover. fleabane. Managing Cover Crops Profitably explores how and why cover crops work, and provides all the information needed to build cover crops into any farming operation. For this reason, clover is an ideal candidate for cover cropprograms in many situations. Crimson clover have been used in forage applications for generations. Spring plowing is preferred because it decreases the potential for nitrogen leaching. Overseeding into standing corn immediately after sidedressing nitrogen or the last cultivation (whichever is later), or before a spring annual's emergence (oats, spring wheat) also provides a good stand. It's easy establishment and shade tolerance make it useful in several cropping sequences. Red clover’s deep roots hold the soil in place. Good varieties of medium red clover include Redland III, Cinnamon Plus, and Bulldog. Red clover is the number one choice of legumes when considering spring interseeding. Cover crops literally make a living “cover” to sustain soil life until spring planting. A red clover cover crop has several benefits, including: 1. A red clover cover crop has several benefits, including: Red clover is most commonly used in rotations between non-leguminous crops, such as corn or small grains (wheat, oats, barley, rye and spelt) followed by a spring-seeded non-leguminous crop (corn, buckwheat, oats, etc.). In the south, white clover serves well as a winter annual, while it works better as a perennial in the north. Prepared by Sjoerd Duiker, associate professor of soil management and applied soil physics, and Bill Curran, professor of weed sciences. Red clover may be the best choice for frost seeding; it is extremely cold hardy and does well in most soils and growing conditions. Crimson clover can be over-seeded in crops such as corn and used after short rotation crops such as snap beans. Spring termination is usually required when red clover is used as a cover crop to guarantee maximum nitrogen fixation. Last year our research showed that the red clover — both at the same harvest date as the alfalfa and at the 40 NDF harvest dates for each — out-yielded the alfalfa in the first harvest. The biomass can also be left to decompose in the field, thus contributing to the soil organic matter pool and the organic nitrogen reserves in the soil. Cover crops: red clover, crimson clover, hairy vetch, field peas, mustards, canola, buckwheat. This table compares the relative effectiveness of herbicides for control of some common legume cover crops. Penn State University Extension – where red clover is more commonly used as a cover crop – has some good guidelines. nitrogen per acre. The lateral roots growing off the main tap root will concentrate in the top 5 inches of topsoil. Do not attempt to establish a stand in corn treated with a pre-emergent broadleaf herbicide (i.e. If red clover is purely grown as a cover crop it can be terminated before a high-nitrogen demanding crop such as corn. Red clover was terminated by disking either in the fall (fall-killed) or spring (spring-killed). Mowing red clover and leaving the cuttings in the field allows additional nitrogen fixation. Originating in Asia Minor and southeastern Europe, it easily spread as an important sown crop throughout Europe, then in England, and finally in America. Medium red is most common. It prefers a soil pH between 6.0 and 7.2. Red clover prefers grasslands and wet meadows, where it grows up to 50 centimeters in height, producing spikes of purple-red color. It can contribute up to 60 lbs. Rye—winter rye or cereal rye—is a great cover crop to plant in the fall or early … Flowering Cover crops such as crimson clover, buckwheat, alfalfa and mustard attract bees and beneficial insects that help with pollination and insect control in the garden. They showed strong growth by the end of September. Planting Specification Guide – Cover Crop November 2011 Page 1 of 8 Cover Crop Planting Specification Guide NH-340 . Use 10 to 15 pounds per acre of red clover seed when broadcast seeding. However, this product does have its limitations when it comes to hard to control broadleaf weeds, i.e. Until sufficiently repeated trials are completed in Pennsylvania, we recommend following these guidelines from Michigan to calculate the pounds of nitrogen supplied per acre by a terminated red clover stand to the following crop: 30 + 0.30 x % stand, where 100 percent is five to six plants per square foot after at least one year of growth. Some farmers broadcast the red clover seed into corn or soybeans prior to last cultivation for weed control, thus improving red clover seed-to-soil contact. Results may differ with variations in cover crop size, temperature, and rainfall.1. An effective method of frost- seeding red clover is to mix the inoculated red clover seed with liquid nitrogen fertilizer and top-dress the mix onto winter small grains in March or early April. Red Clover. Cutting red clover may stimulate new growth and, hence, additional nitrogen fixation. With the potential to produce 100 + lbs. As a forage crop, red clover is seeded in spring sometimes alone and sometimes with a companion crop such as oats. Status Please consult the PLANTS Web site and your State It also serve as a habitat for beneficial predators. Contributing up to 120 pounds of soil nitrogen for the following crop rotation, Reducing soil erosion and surface water pollution, Increasing soil organic matter, improving soil tilth and increasing water holding capacities, Reducing grass and broadleaf weed pressure, Serving as a forage and/or pasture species, Frost-seeding into an established winter annual (wheat, barley, rye or spelt) is the most common method. Red clover can also simply be broadcast in corn or soybeans without cultivation. Several studies have shown that the nitrogen benefit from the legume is similar whether it is incorporated or left on the surface as mulch. With a 100 percent stand, 60 pounds of nitrogen per acre would be contributed by the red clover to the following crop. Tolerance of shade allows red clover to be used effectively as a cover crop under silage corn. Red clover may be the best choice for frost seeding; it is extremely cold hardy and does well in most soils and growing conditions. In this case, using 6 to 10 pounds of seed per acre is recommended. Its ability to handle both shade and heat make it ideal for this. Why do we need this? Selecting Cover Crops . Its easy establishment and shade tolerance make it useful in several cropping sequences. Entering your postal code will help us provide news or event updates for your area. With the potential to produce 100 + lbs. • Red clover (Trifolium pretense) (Figure 7) is a short- lived perennial cover crop, but it is sometimes used in annual crop rotations when there is a longer win- dow for cover cropping. ), it’s a good idea to review or at least acknowledge some of the core weed science ideas due to the similarities between weeds and cover crops. Red clover is also considered as a medicinal plant. Its ability to handle both shade and heat make it ideal for this. Red Clover. The earlier the red clover is established, the more benefits it can be expected to produce the following year. Red clover is a useful forage crop and often harvested for hay. Red clover prefers grasslands and wet meadows, where it grows up to 50 centimeters in height, producing spikes of purple-red color. Widely grown biennial used for Nitrogen addition and hay crops. Broadcast 10-12 lb/A of seed (any cultivar). It is a legume and has been used as a cover crop like white clover. it does, like most clovers, perform poorly in hot weather unless seeded into a crop canopy. sativum An excellent fast-growing cover crop that can be planted almost any time of the year. j Email us about this product. If it survives through the winter it can be terminated mechanically. Mammoth Red clover will fix up to 70-110 lbs. Michigan State University Extension programs and materials are open to all without regard to race, color, national origin, gender, gender identity, religion, age, height, weight, disability, political beliefs, sexual orientation, marital status, family status or veteran status. It is important to minimize the time that the seed and inoculant are in the fertilizer solution to maintain viability of the seed and bacteria. Reducing grass and broadleaf weed pressure 5. Legumes: crimson clover (Trifolium incarnatum) red clover (Trifolium pratense) hairy vetch (Vicia villosa) Austrian winter pea (Pisum sativum subsp. Red clover (Trifolium pratense) is Michigan's most common cover crop. Select fields that have relatively good weed control, as clover seedlings do not compete well with established weeds. The main control methods are: The amount of nitrogen contributed by the red clover will depend on the density of the stand and the time of year that the clover was killed. Seeding rate should be 6 to 15 pounds per acre (lower rate if drilled; higher when broadcast). Drilling after harvesting silage or high-moisture corn, or with a winter or spring annual using a "grass box" attached to the drill. Product Description: Trifolium pratense var. Red clover is primarily used for hay, pasture, silage, and soil improvement. The lateral roots growing off the main tap root will concentrate in the top 5 inches of topsoil. Full-season, over-wintered red clover can produce 2 to 4 T dry matter/A and fix 70 to 150 lb. Ratings are based on labeled application rates. However, leaving the mulch at the surface will provide better erosion control and will lead to better soil quality. Apply nitrogen fertilizer uniformly and at application rates based on proven small grain yields. It is common for a good red clover stand to provide 80 to 100 pounds per acre of nitrogen fertilizer equivalent. They recommend the following: “An excellent herbicide program to terminate a red clover stand prior to planting corn is one pint of 2,4-D LVE and one pint of dicamba (Banvel or Clarity). Red clover does best on well-drained soil, but it also tolerates poorly drained soil. Cover crops can provide a wonderful habitat for the pollinators that help keep your garden thriving. The drawback of mixtures is that the red clover experiences competition from the companion crop and is likely to produce less growth. Kim Cassida and Jerry Lindquist – Michigan State University Extension . Apply 2,4 D and/or dicamba 7 to 14 days prior to or 3 to 5 days after corn planting if corn seeds are planted at least 1.5 inches deep. Using these numbers, we estimate that in 2011/12 red clover fixed 72 lb N/ac by the time of fall termination and 98 lb N/ac by the time of spring termination. Red clover is a perennial legume and useful in rotation with non-legume crops as a soil nitrogen contributor. We did not measure how much of red clover biomass N was taken up from the soil and how much was fixed, but other studies found that about 75% of N in undersown red clover was from N fixation (Drinkwater and Schipanski, 2011). Large plant with big leaves makes it an ideal grazing crop. Emergence occurs in just 7 days which is faster than most other legumes but the seedling growth is still slow. It makes an excellent cover or green manure crop and improves soils greatly. Use a crop scout to determine if a soil insecticide is justified. Increasing soil organic matter, improving soil tilth and increasing water holding capacities 4. Establishing a dense stand is critical to realizing a red clover cover crop's full value. It prefers a soil pH between 6.0 and 7.2. Red Clover is also utilized in any mixes where the cover crop will also be used for grazing or forage. ; Broadcast inoculated seed over the soil at a rate of one-half pound per 500 square feet of garden. The moldboard plow is most effective in terminating a red clover stand. It is … of nitrogen, it is a nice addition to mixes. For cool-season cover crops (planted in late summer/fall), annuals are the way to go. The plant is said to have originated from a wild strain native to Syria, Lebanon and Israel which is now extinct. Follow label guidelines. Michigan mammoth is scarce and is often sold out by March, so order early to ensure delivery. For example, red clover is a good crop to plant in July or August for termination the following spring. 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. Michigan mammoth has been shown to perform better than the other red clovers when frost-seeded into well-fertilized wheat (Table 1), but is not as productive a forage crop as June clover. MAMMOTH RED CLOVER. For example, red clover is a good crop to plant in July or August for termination the following spring. Red clover: Managing Cover Crops Profitably (SARE Handbook Series Book 9) by Andy Clark (2007, 3rd ed.) Make sure the nozzles have an orifice large enough to keep them from becoming clogged up. Again, use a post-emergence broadleaf program instead of establishing a clover stand in corn treated with a pre-emergence broadleaf herbicide (i.e. Thus, a stand of two plants per square foot would represent a one-third (33 percent) stand, which would be expected to contribute 40 pounds of nitrogen per acre. The cover crops were interseeded in soybean at 0 or 2 wks after planting soybean in 2002 and killed with herbicide before planting corn in 2003. Perennial cover crops such as red clover (Trifolium pratense) are slow growing and are best used in orchards and vineyards. Red clover seed may be applied with urea if the mixing and application operations are uniform. 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. Cover crop establishment was considered similar with both methods. Red clover’s deep roots hold the soil in place. Red clover can be used as a cover crop that provides many benefits such as fixing nitrogen (N) to meet needs of the following crop, protecting soil from erosion, improving soil tilth, competing with weeds, as well as supplying forage needs. Glyphosate rate in lbs ae/acre; 0.5 lb paraquat = 2 pt Gramoxone Inteon; 0.195 lb clopyralid = 5 oz Hornet, 78.5 WDG, or 6.7 fl oz Stinger 3S. So, check seeding depth in the field, especially when using a no-till drill. Biomass of red clover and radish after grain harvest was higher than annual ryegrass and the biomass of the red clover the subsequent spring was higher than the annual ryegrass. It is winter hardy in USDA Hardiness Zone 4, which means red clover survives the winter in all of Pennsylvania. undersown in an arable silage crop, or after a cereal grain crop. Do not plant soybeans after dicamba application. Broadcasting red clover seed into soybeans just before leaf fall (when soybean leaves start to turn yellow) has been proven a successful method. Prepare the garden so you can seed the clover six to eight weeks before the average first frost date in the area. The best winter cover crops differ from region to region, by growing zone and the crop's winter hardiness, but from a management perspective there are basically two types, winter-killed and winter-hardy, along with a third, blended type of the two. Canadian-grown mammoth clover does not tolerate the increased shading and competition from well-fertilized wheat, but works well when seeded with oats. Ohio-grown mammoth clover should perform nearly as well as Michigan grown mammoth in well-fertilized wheat. Red clover is also considered as a medicinal plant. Cover crops may be used in any size garden—from a 4’x4’ raised bed to a large farm or open field! It is quicker to establish than mammoth and grows back well after it is cut. Red clover season and termination times The plant is not tolerant of extreme heat or cold but thrives in moderately dry to extremely wet regions. If their many benefits haven’t convinced you to do away with sprays and chemicals forever, then maybe a look at some of the best cover crops – and how to incorporate them into your garden plan – will do the trick. Clover seedlings are resistant to frost, so the seed can be broadcast as early as soil conditions permit. Management. The cover crops were planted with a no-till drill in mid-August.
