The Rants’ soil is also on the receiving end of the multiple benefits of white and crimson clover cover crops. Depending on the type, plants grow just 6 to 12 inches tall, but thrive when mowed or grazed. The best of 36 varieties tested in north-central Mississippi for cover crop use were ARAN, GRASSLAND KOPU and KITAOOHA. White clover should be drilled at 3-9 pounds per acre, and broadcasted at 5-14 pounds per acre. 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. A terrific green manure as it fixes up to 170 pounds of nitrogen per acre and attracts beneficial insects. The co-chair of the Dodge County Farmers for Healthy Soil & Healthy Water talks about strip-cropping and interseeding cover crops at a field day in the summer of 2020. They add organic matter to the soil and add nitrogen in a slow-release way. White clover stores up to 45 percent of its N contribution in its roots, more than any other major legume cover crop. However, only intensive irrigation and mowing prevented moisture competition. N/A when killed the year after establishment. Does well interseeded, frost seeded, or in a cover crop mix; There are many other types of clover including berseem, alsike, sweet, red, balansa, etc. White clover performs best when it has plenty of lime, potash, calcium and phosphorus, but it tolerates poor conditions better than most clovers. Thanks to cover crops such as white and crimson clover taking center stage on their two family farms, the blueberry crop is thriving and the farmers are reaping significant rewards. Its perennial nature depends on new plants continually being formed by its creeping stolons and, if it reaches maturity, by reseeding. It grows slowly while shaded as it develops its root system, then grows rapidly when it receives more light. During early stages of development and growth, a grower needs to make sure the white clover is not outcompeting with any cash crops for light, nutrients and moisture. MERIT ladino clover was the most efficient of eight major legumes evaluated in a Nebraska greenhouse for N2 fixed per unit of water at 50° F. Ladino clover, as well as hairy vetch and fava beans (Vicia faba) were the only legumes to grow well at the 50° F temperature (334). While rye, an annual cover crop, required tillage in fall before planting and in spring to kill and incorporate, perennial white clover could be grown for two or more years without tilling. They managed the farm until retirement without going into debt—something of an accomplishment during that period—but the operation never really took off. The large (Ladino) types produce the most N per acre of any white types, and are valued for forage quality, especially on poorly drained soil. White clover should be drilled at 3-9 pounds per acre, and broadcasted at 5-14 pounds per acre. Early screening of different cover crops led Rant to further test crimson clover, a winter annual cover crop that not only grows well in fall and spring, but also shows great potential to reseed itself, further reducing costs. Use higher seeding rates (5 to 9 lb./A drilled, 7 to 14 lb./A broadcast) when you overseed in adverse situations caused by drought, crop residue or vegetative competition. So which ones are for you? Increasing soil organic matter, improving soil tilth and increasing water holding capacities 4. Poor seed establishment and lagging clover growth in the drier year created weed problems, especially with perennial competitors. 66 to 72, for ranking and management summary. I see my fields as one unified system, and the biology of the soil in the inter-rows is as important as the soil and fertility up and down my blueberry rows.”. Mutch and Michigan State researcher Rufus Isaacs are helping to elucidate other management aspects of clover cover crops, such as whether honeybees and native bees such as mason bees and sweat bees are attracted to clovers. Compacted soils are a problem for blueberries, which prefer loose, friable soil. If not cut or grazed to stimulate new growth, the buildup of vegetation on aged stolons and stems creates a susceptibility to disease and insect problems. Seeding about 40 days before the first killing frost is usually enough time. Sow 1/4 pound per 1000 square feet; 6–10 pounds per acre. Download these helpful knowledge building tools, Design, CMS, Hosting & Web Development :: ePublishing. Value-added forage. To safely overwinter white clover, leave 3 to 4 inches (6 to 8 inches for taller types) to prevent frost damage. - 2000 lb. Michigan blueberry growers find that it improves pollination, as does crimson clover (see Clovers Build Soil, Blueberry Production. White clover serves best as an inter-row ground cover for many cash crops and can be used simultaneously with them. It reduces compaction and dust while protecting wet soil against trauma from vehicle wheels. Broadcast inoculated seed over the soil at a rate of one-half pound per 500 square feet of garden. Its extensive root system breaks up compaction, while the ground cover also keeps soil from running off while still holding key nutrients in place. Drill 4 to 6 lb./A when mixing white clover with other legumes or grasses to reduce competition for light, moisture and nutrients. Spring growth of fall-seeded white clover begins in mid-May in the Midwest, about the same time as alfalfa. Seeking something that will not compete with the cash crop, most farmers choose rye or sod. Common cover crops include annual ryegrass, Sudan grass, oats, buckwheat and legumes, such as peas, beans, alfalfa, clover and vetch. Crimson clover is now recognized as one of the best cover crops available. As a living mulch, white clover gives benefits above and below ground while it grows between rows of cash crops, primarily in fruits, vegetables, orchards and vineyards. Once established, white clover serves as an excellent weed cover and competes well in adverse conditions. Once established, they stand up well to heavy field traffic and thrive under cool, moist conditions and shade. Unsuppressed white Dutch clover established at asparagus planting controlled weeds and provided N over time to the asparagus in a Wisconsin study, but reduced yield significantly. To be profitable commercially, the system would require irrigation or a less thirsty legume, as well as field-scale equipment able to mow between several rows in a single pass (93). Hand mowing/in-row mulch. Living mulch fields can be overseeded with grasses or other legumes to rotate into pasture after vegetable crops, providing IPM options and economic flexibility. Mutch and Rant are studying crimson clover reseeding, another cost-saving measure, comparing mowing and tilling the crimson clover after it has set seed. Protect against pest problems by selecting resistant cultivars, rotating crops, maintaining soil fertility and employing proper cutting schedules (361). Spreading soil protector. They can also be used as a mulch. To receive the multiple benefits, manage the covers carefully throughout early crop growth—to keep them from competing with the main crop for light, nutrients, and especially moisture—while not killing them. This spacing yielded higher corn growth rates, more marketable ears per plant and higher crop yields than conventional plots without clover in an Oregon study. Intermediate types of white clover include many cultivated varieties, most originally bred for forage.

A California study showed that frequent mowing can work with careful management. Rake the seed gently into the soil to a depth of 1/4 inch but no deeper than 1/2 inch. Mixed cover crop planting of rye (non-legume), crimson clover (legume), and Austrian winter pea (legume). White clover converts vulnerable bare soil into biologically active soil with habitat for beneficial organisms above and below the soil surface. Partial rotary tillage. Leguminous plants are able to host bacteria that take nitrogen from the air and fix it in nodules on root hairs. The short and intermediate types are low biomass producers, while the large ladino types popular with graziers can produce as much biomass as any clover species. White clover can tolerate wet soil—even short flooding—and short dry spells, and survives on medium to acid soils down to pH 5.5. The lowest growing type (Wild White) best survives heavy traffic and grazing. They are generally less durable, but may be two to four times taller than intermediate types. In the heart of blueberry country in the leading blueberry state in the U.S., Richard James “RJ” Rant and his mother, Judy Rant, are breaking new ground and reaping great rewards. Clover as a cover crop for cannabis plants January 18, 2021 admin Growing Cannabis 5 White dutch clover seeds: Red clover seeds: “A cover crop is a crop … White clover serves as the premier living mulch system over any other legume. His focus on soil-building and cover crops proved key to the success of their operation, now expanded to two farms: Double-R Blueberry Farm and Wind Dancer Farms, jointly operated by RJ and his mother, Judy. White clover can also be frost-seeded early in the morning when frost is in the soil. Green manures include legumes such as vetch, clover, beans and peas; grasses such as annual ryegrass, oats, rapeseed, winter wheat and winter rye; and buckwheat. It volunteers on a wider range of soils than most legumes, but grows better in clay and loam soils than on sandy soils (120). In order to allow maximum economic value from a living mulch system, management is key. White clover’s persistence in the face of some herbicides and minor tillage is used to advantage in these systems (described below) for vegetables, orchards and vineyards. When mixing with another cover crop, drill at 4-6 pounds per acre. A surge of N within a month of tilling aided the growing corn. As with all cover crops, killing time for crimson clover is determined by the planting date for the succeeding crop and/or soil moisture. For late summer seeding, seed about 40 days before the first killing frost to allow establishment. “The reason I keep using them is because they save me time and money.”. It will be impossible to mow since it’s a raised bed. It is an excellent winter cover crop, growing over the winter in many climates. The variety tends to grow more quickly in fall and spring. Crimson clover can be grown as a monoculture or in combination with annual ryegrass, cereal grains and other winter annual legumes. Cover crops like FIXatioN Balansa Clover can be an important source of nutrients for the following crops. Cover crops are “green manures” when a gardener turns them into the soil to provide organic matter and nutrients. Sweetclover is used as a cover crop most commonly now in the Plains region, with little use in California. Some well known examples of allelopathic cover crops are Secale cereale (rye), Vicia villosa (hairy vetch), Trifolium pratense (red clover), Sorghum bicolor (sorghum-sudangrass), and species in the family Brassicaceae, particularly mustards. Adapted row-harvesting equipment and handpicking would be needed to make the spacing practical (139). RJ Rant took a different tack. New Zealand white clover provided good weed control for winter squash in the wetter of two years in a New York trial. These ranked high for all traits tested, including plant vigor, leaf area, dry matter yield, number of seed-heads, lateness of flowering and upright stems to prevent soil contact. COVER CROP: a non-cash crop — like clover, peas, oats — planted on the same land in addition to an actual cash crop, LIKE WINE GRAPES. Ladino and alsike are the best hay-type legumes on poorly drained soils. The loss of root and nodule tissue following stress from tillage or herbicide shock seems to release N from the clover. Late-summer seeding must be early enough to give white clover time to become well established, because fall freezing and thawing can readily heave the small, shallow-rooted plants. Select insect management measures that minimize negative impact on bees and other pollinators. Their sandy loam soils were decent but not excellent, and his research led him to focus his efforts on improving the soil by reducing tillage and planting cover crops. Taller ladino types can be grazed or harvested. The mix is 50 percent white Dutch clover, 30 percent berseem clover, and 20 percent HUIA white clover, which is a bit taller than the white Dutch. Ranking high were ANGEL GALLARDO, CALIFORNIA LADINO and widely used LOUISIANA S-1 (392). Clover Cover Crop – Mow Before Tilling? Crimson clover, red clover, and white Dutch clover are all used as cover crops. Today, it is the most common legume cover crop and forage plant for livestock in the U.S. Extremely close mowing and partial tillage that leaves any roots undisturbed will suppress, but not kill, white clover. Crimson clover (Trifolium incarnatum) is native to the Mediterranean region. Three cover crop categories exist: Grasses like cereal rye and Sudan grass; brassicas like turnips, radishes, and rapeseed; and legumes like hairy vetch and clover. All cover crops significantly reduced nitrate-N accumulations in Iowa State University (ISU) trials. He mows the field in fall, then broadcasts medium red clover early the next spring to establish a hay field and replace the berseem, which is not winter hardy (259). Choosing farming over graduate school, RJ began a quest to improve the blueberry operation and its bottom line. Crop shading. He cooperates with researcher Dale Mutch to fine-tune cover crop selection, planting methods and management options. This site is maintained by SARE Outreach for the SARE program and is based upon work supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, under award No. Although mowing (even five times) didn’t sufficiently suppress clover, partial rotary tilling at two weeks after emergence worked well. A Penn State Extension publication on management of red clover as a cover crop includes the following statement, “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. Mixes must be ordered 2 weeks prior to … White clovers are fairly tolerant of nematodes and leaf diseases, but are susceptible to root and stolon rots. 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. A white clover cover reduced levels of cabbage aphids in harvested broccoli heads compared with clean cultivated broccoli. Sweetclover was the king of green manures and grazing legumes in the South and later throughout the Midwest in the first half of this century. When mixing with another cover crop, drill at 4-6 pounds per acre. In selecting a fall-seeded N-producer, consider white clover in areas with extended cool springs. To build better soil structure, Rant is working with MSU’s Mutch to improve soil organic matter with cover crop mulches and manures.
