No-till planting into a cover crop involves minimal soil disturbance—that is, opening only a narrow furrow for the seed. Depending on the grass and legume cover crops chosen, a reduction in seeding rate may be appropriate. Legume cover crops are most likely to be adopted in the following scenarios: One way to reduce the establishment costs of cover crops is to manage them for reseeding. Reseeding usually will not work for crimson clover planted before full-season field corn because crimson clover seed matures after corn planting dates. Woollypod vetch is a cool season annual legume, comparable to many other vetches but with a few of its own unique characteristics. Being a very versatile vetch, it can grow in many types of soil conditions including even poor fertility or sandy soils. A Florida based worldwide supplier of Lawn, Pasture and Turf Grass Seed at wholesale pricing direct to the public! Using a small grain cover crop for silage or hay will greatly delay corn planting and thereby increase the risks of drought, heat stress, and pests associated with late planting. Figure 5. To plant hairy vetch, plow the soil as you would for any regular crop. Winter annual cover crops have been used in rotation with summer crops for many years in North Carolina, but now there are some interesting new applications of this practice. Cover the seeds with about ½ inch of soil, then water well. Winter annual cover crops can be either legumes or cereals. Estimated costs associated with a legume cover crop include seed ($55/acre for hairy vetch at 25 pounds per acre), inoculation ($2/acre), planting ($8/acre), and burndown herbicide ($10/acre), for a total of $75/acre. With a very low C:N ratio the residue breaks down very quickly and will leave the soil bare throughout much of the growing season. Timing is particularly important with legumes because late seeding results in small plants with limited root systems. A. Kranz. Management decisions such as the date and method of killing a cover crop influence the amount of cover crop growth and nutrient uptake, as well as the availability of the nutrients released to a following crop by decomposition. seed will mature, but care must be taken to insure Smith, F.S., A.D. Falk, and W.R. Ocumpaugh. Drill 15-20 lbs/A hairy vetch seed 1-1.5 inches deep (use higher seeding rate when planning to terminate hairy vetch early in spring). This alleopathic reaction has been attributed to the release of phytotoxic chemicals from decomposing residue. However, it is also less winter hardy than hairy vetch. Hairy vetch can contribute up to 100 pounds of nitrogen per acre when it is well adapted. Cooperative Extension county center. The legumes best adapted to North Carolina soil and climatic conditions are crimson clover, hairy vetch, Austrian winter pea, and Cahaba white vetch. A: Cover crop wheat planted to protect stale seed beds during the winter. Many farmers use smallgrain cover crops to control erosion. Hairy Vetch is a viney, cool season legume best used in a crop rotation for erosion control or as a cover crop. Be notified by email when this product is back in stock. This species is really known for its climbing ability, even more so than common vetch. Use seed that has been inoculated with the appropriate rhizobium strain (hairy vetch/pea group Rhizobium leguminosarum biovar viceae) to guarantee nitrogen fixation. The ideal temperatures for early root growth range from 20° to 25° C (68° to 77° F). There are many combinations to choose from: using winter wheat or cereal rye; planting flat or on beds; and planting the following crop no-till, strip-till, or conventional till. Decomposition of legume residues proceeds rapidly under favorable conditions, and most of the N becomes available before the corn tassels and silks or by the time it is needed by grain sorghum or most short-season vegetable crops. Latin Name: Vicia villosa Common Names: Winter Vetch, Fodder Vetch, Sand Vetch Hairy Vetch Hardiness Zones: Perennial to zones 1-7, Annual cover crop Days to Maturity: 80-90 days (longer when left to germinate over winter) Hairy Vetch Seeding Rate: 1-2 lb per 1000 sq. Woollypod vetch excretes root exudates that can reduce the … Hairy vetch is ideal ahead of early-summer planted or transplanted crops, providing N and an organic mulch. A lower seed cost for crimson clover (approximately $1/pound) results in a total cost of $45 per acre. Hairy vetch is a hardy type of vetch suited to wetter soil and colder winters than other winter-active legumes. 1998. If legumes are used, an early burndown is likely to reduce the amount of legume N available to the next crop. Anderson, J. R., N. L. Hubbard, F. D. Shaw, and F. W. Smith. Hairy Vetch performs best on well-drained soils and mild soil conditions. Cover crop growth can be terminated by tillage, rolling, or herbicides. Growing Organic Hairy Vetch Cover Crop Garden Seeds. *Based on a 1-10 scale. For Austrian winter pea, the rates are 25 to 35 pounds per acre broadcast and 20 to 25 pounds drilled. Mix with cereal rye for increased weed suppression and increased winter survival of hairy vetch; Soil health benefits: source of nitrogen, increases weed control; Slow-growing cover crop so seed early for best growth; Not a good option for grazing. No-Till Farm and Garden Cover Crop Mix Seeds - 1 Lbs - Blend of Gardening Cover Crop Seeds: Hairy Vetch, Daikon Radish, Forage Collards, Triticale, More Visit the Mountain Valley Seed Company Store 4.4 out of 5 stars 384 ratings An innovative system that has shown promise in other southeastern states is to allow crimson clover to reseed itself naturally. This surface mulch enhances summer rainfall infiltration, reduces soil water evaporation, and provides weed control by early shading. FARM SEED SALES & PICK UP. With careful management, this system can work for full-season no-till corn if strips of crimson clover are allowed to mature, produce, and disperse seed (as discussed in the “Legume N Economics” section, below). Corn yields in the piedmont are lower after small grain silage removal compared to leaving the small grain as mulch. Woollypod vetch has the potential to grow faster and earlier than hairy vetch. The Heart of Organic Growing Those who buy organic food often describe organic farming and gardening in the negative: as growing crops without using synthetic … Green Manures Read More » Hairy vetch is a winter-hardy cover crop that can grow in areas that undergo a hard freeze. At a Wayne County site, the thin crimson clover cover stand on the left was planted late (November 19), whereas the plot on the right was planted as recommended on October 12. If planted in the spring, weed competition could be an issue and the vetch should be allowed to grow to at least memorial day to justify your investment. The nonlegumes rye and triticale provide maximum erosion protection during fall and winter because of their rapid growth rates. Some producers may find the late maturity of WinterKing reduces the potential for undesired seed propagation found in earlier maturing cover crop varieties. If a legume cover crop contributes 100 pounds of N/ acre, the legumes would cost the equivalent of a typical inorganic N fertilizer (30% N as UAN solution) priced at $275 to $450/ton for crimson clover and hairy vetch, respectively (Figure 9). However, do not delay corn planting to allow additional growth of legume cover crops. Beltsville, MD: Sustainable Agriculture Network. Wind erosion can be severe in cultivated organic and sandy soils of this region (Figure 3A). Thus, they can reduce crop growth unless sufficient inorganic N is applied (Figure 2). In many areas of North Carolina, nutrient management is becoming increasingly important as farmers do their part to protect surface waters from nutrient loading. Best prices on grass seed guaranteed! As previously discussed, seeding depth varies from 1⁄2 to 11⁄2 inches, depending on soil texture. For both hairy vetch and Cahaba white vetch, the rates are 20 to 30 pounds per acre broadcast and 15 to 20 pounds drilled. Seed pea vetch. Hairy vetch is a winter annual legume and one of the most productive at nitrogen fixation. This thick thatch will slow soil warming and drying and this could cause some issues in a no-till system. When grown for hay, vetch is generally cut when the first pods are set. * Dry matter and N accumulation were significantly reduced if planting was delayed until November following harvest of a maturity group 5 soybean (P<0.05). The extent of soil erosion control provided by cover crops during the fall, winter, and early spring depends largely on when the crop is established (Figure 5). In contrast to legume cover crops, small grain covers can reduce available soil N early in the growing season. Freeze damage has also occurred with Austrian winter pea in higher elevations (above 2,500 feet). For this reason, fertilizer N application rates should reflect both cover crop and summer crop potential constraints, with attention being given to timing and placement of fertilizer N to promote high yields (Table 6). In general, planting late (late October to November) in the piedmont and mountains will increase the risk of winter kill. Cover crop residue usually does not promote a higher population of nematodes in no-till corn. Woollypod vetch has the potential to grow faster and earlier than hairy vetch. B: Water erosion on sloping land. 2. Rye cover crop terminated by a roller-crimper prior to planting certified organic soybeans. This vigorous, fast-growing perennial grows in 2-foot tall mounds. Woollypod vetch can be more sensitive to cold weather fluctuations than some other vetches. Management to achieve sufficient cover crop biomass entails planting in September or October and killing about April 1 in the east and in mid- to late April in the piedmont and mountains. Seeds that have a hard seed coat can lay dormant in the soil for over five years. Drilling depth can be up to an inch lower, if planted early but if broadcasting is the method used than a shallow incorporation is suggested. However, situations occur that make weed control very difficult under no-till management. Surface residue cools the soil considerably during the spring, with late-summer differences between the cover and bare soil lessening as the corn crop begins to shade the soil. Technical Bulletin no. This seed is then naturally dispersed and can germinate late in the summer when moisture becomes sufficient. Crimson clover productivity has been much lower on poorly drained soils, with N accumulations of less than 25 lb/acre in some recent field trials. In Figure 2, maximum yield was attained with both 104 lb fertilizer N/acre and with 54 lb fertilizer N/acre plus vetch; thus, vetch appears to supply the equivalent of 50 lb N/acre. Soybeans are never harvested early enough for the seeding of legume cover crops. Planting methods are the same as those described for legumes. Hairy vetch tends to be more winter hardy than the others and generally can be planted later. Determine small grain lime and fertilizer needs based on soil test results. Growth correlates with growing degree days (units of average daily temperature compared to a base at which no growth takes place) which are calculated for hairy vetch using a base temperature of 4° C (39.2° F). 1 = Poor : 5 = Average : 10 = Excellent. 10% - 30% vetch inclusion in a whole crop mixture with cereals and or peas. It can also be used in feed as hay, silage or grazing due to its high crude protein content. commitment to diversity. Either Gramoxone Super or Roundup can be used to control existing cover crop vegetation. Crown vetch (Coronilla varia) is planted as a ground cover and grown on disturbed slopes to stop erosion. Mixture Sowing Rate Advice. Hairy vetch is not a crop that would planted as a monoculture if your goal is to build organic matter. Kamprath, E. J., W. V. Chandler, and B. A&T State University. Cooperative Extension prohibits discrimination and harassment regardless of age, color, disability, family and marital status, gender identity, national origin, political beliefs, race, religion, sex (including pregnancy), sexual orientation and veteran status. Surface residue (from a cover crop or previous crop) helps conserve soil moisture during the spring/summer growing season by reducing water evaporation from the soil surface before the protective full crop canopy has been established. Consult the North Carolina Agricultural Chemicals Manual for the appropriate residual herbicide combinations. Legumes grow only a limited amount during fall and winter, which makes them a poor choice for grazing during this period. In addition to protecting land from erosion, hairy vetch can provide spring pasture for livestock. A wide range of planting dates exists for most legumes (Table 1), although early plantings obtain the best results. Limited research indicates that these soils respond to subsoiling even with the presence of a cover crop mulch. Harvesting can be made easier if the seed crop is sown with 10–15 kg oat seed/ha. Hairy vetch prefers well-drained soils with a pH of 6.0-7.0, and will do poorly in clay or wet fields. Seed corn insects can be abundant in cover crops used as no-till mulch. Proper field scouting is important in determining the need for postemergence weed control measures. Positive yield responses in corn have been documented when planted after Woollypod vetch and there is no known hazards of increasing insect pest issues. When cereal rye is planted early in the fall alone and in mixtures, it can greatly reduce available soil nitrogen that can be subject to leaching during the wet winter months. Do note that a cover crop depletes soil moisture during active growth, and it may be difficult to obtain adequate corn stands during dry spring seasons. The forage produced is palatable when green but palatability will greatly increase as it's dried down. The following general cultural practices are applicable to all legume cover crops: Planting dates. For pasture: A field of fall-seeded rye and vetch can be pastured from early May through June, then plowed and sown... 3. Nevertheless, few if any, large commercial farmers have adopted legume cover crops to supply N, probably because of cost (see next section) and management reasons. When the summer crops are grain sorghum or warm season vegetable crops, planting dates can be more flexible. When allowed to overwinter, the extra growth aids in smothering out weed competition and protecting the soil. Variation in soil temperature at 2" depth with selected cover crops. Descriptions of many potential cover crop species can be found in the US Department of Agriculture publication Managing Cover Crops Profitably. Two or more cover crop species can be combined in a single planting to realize the benefits of each. Erosion caused by wind and water are much greater on bare ground than on a surface protected by a cover crop. Vetches have the ability to offer substantial improvements in soil fertility, structure and organic matter as well as offering a weed and disease break for cereals in a crop rotation. This method will work in North Carolina where the following crop is midsummer vegetable crops (pumpkins), grain sorghum, or tropical silage corn (late spring establishment). Seed crimson clover at 20 to 25 pounds per acre broadcast and 15 to 20 pounds drilled. North Carolina Agricultural Chemicals Manual. Other management factors in a no-till system are similar to practices used with conventional tillage. N.C. This means using a spray volume of 20 to 60 gallons per acre for Gramoxone and 10 to 30 gallons of water per acre for Roundup. Grazing or hay crop. Hairy vetch has consistently performed well in these trials, and crimson clover is also promising on well-drained sites (Figure 2; Table 3). If small grain must be planted before frost, consider choosing an alternative small grain. Managing Cover Crops Profitably. If Hessian fly is present in your area, wheat should be planted after the first fall frost. Use 11⁄2 to 21⁄2 pints of Gramoxone Super per acre or 11⁄2 to 2 quarts of Roundup per acre. Cereals or small grains that are best for North Carolina are rye, wheat, barley, triticale, and oats. 129. Hessian fly does not inhabit rye, triticale, barley, or oats. Common vetch, Vicia sativa, does not produce as much seed as hairy vetch, posing less of a risk of becoming weedy. Several studies comparing conventional and no-till corn in eastern North Carolina have documented the potential contribution of N by legumes. Sorghum Sudan (Sweet Six Dry Stalk BMR) - Hybrid. Woollypod vetch is the earliest maturing/blooming commercially available vetch. In some instances, the effectiveness of both Gramoxone and Roundup on actively growing legumes has been enhanced by the addition of 2,4-D amine (1⁄2 to 1 pint per acre) or Banvel (1⁄2 pint per acre tank-mixed). Application Rate: 1 lb/1000 sq ft or 30-40 lb/acre In other cases, producers plant it with winter annual grasses, especially small grains. Cooperative Extension, College of Agriculture and Life Sciences, NC State University. Winter Cover Crops: Their Effects on Corn Yields and Soil Properties. Figure 3. Cooperative Extension is based at North Carolina's two land-grant institutions, For corn following a small grain cover crop, special consideration must be given to fertilization, especially with regard to the N source, placement, and timing of application. With an overall rate of 75 kg per acre / 187.5 kg per ha. Planting about a quarter of your garden to cover crops each year can add fertility, reduce erosion, help break pest cycles, and much more. Raleigh, NC: N.C. ... Cover Crop Seed Mixtures. With the early harvest and the open fall this year, there is enough time for a cover crop to be seeded and to have adequate growth to provide some benefits. Broadcast the seed over the soil at the rate recommended on the seed package – usually 1 to 2 pounds of seed for every 1,000 square feet of garden space. Figure 7. In contrast, the presence of a cover crop, particularly rye, has had a beneficial effect on weed control by suppressing germination of many large-seeded broadleaf weeds. They then harvest the forage for hay or silage. Spray solutions for Gramoxone can be water, nitrogen solution, or clear fertilizer solutions and must contain a nonionic surfactant. Even if economic factors do not favor the use of legume cover crops to supply N, farmers may be interested in building organic matter, enhancing available soil moisture, and benefiting the complex ecosystem effects that are often associated with legume and grass cover crops. In strip tillage systems or with banded herbicide applications, a crimson clover cover crop can be managed so that a proportion of the stand is allowed to continue growing and produce viable seed. Crimson clover, in particular, can be established quite easily with this method. Aerial seeding of rye into soybeans just before leaf drop has been marginally successful. This field is for validation purposes and should be left unchanged. of nitrogen per acre to a following spring crop. Cover crops in a conservation tillage planting system provide erosion control during the winter while the plant is growing and mulch for the soil surface during the summer in the form of crop residue. An example of crimson clover and hairy vetch cover crops. Raleigh, NC: Proceedings of the 1990 Southern Region Conservation Tillage Conference. 1990. Thus, they may act as a net drain rather than as a contributor of N to the system. Terminate before seed production to avoid hard seed Remember, though, that late seeding dates may sacrifice some soil erosion protection. Cultipacking after broadcasting will encourage good soil/ seed contact. In Figure 9, prices can fluctuate dramatically, but current total production cost estimates are $60–$75/acre/year for hairy vetch, $45–$60/acre/year for seeded crimson clover, <$30/acre/year for self-reseeding crimson clover, $40–$60/acre/year for winter pea, and $300–$400/ton for an inorganic fertilizer with 30% N as a UAN solution.
