The cover also decreases rainfall runoff and increases water infiltration. Hairy Vetch performs best on well-drained soils and mild soil conditions. 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. For double-cropped soybeans planted into small grain stubble, insect damage is no greater than with conventional tillage. Anderson, J. R., N. L. Hubbard, F. D. Shaw, and F. W. Smith. 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 » commitment to diversity. For Austrian winter pea, the rates are 25 to 35 pounds per acre broadcast and 20 to 25 pounds drilled. The use of brand names and any mention or listing of commercial products or services in this publication does not imply endorsement by NC State University or N.C. A&T State University nor discrimination against similar products or services not mentioned. Be notified by email when this product is back in stock. Either Gramoxone Super or Roundup can be used to control existing cover crop vegetation. This seed is then naturally dispersed and can germinate late in the summer when moisture becomes sufficient. All these potential benefits are highly dependent on weather and management factors that should be considered when using cover crops. A: Wind erosion during cultivation of a Roper muck. Small grains and other grasses help control erosion caused by wind or water (Figure 3). Figure 10. Determine small grain lime and fertilizer needs based on soil test results. Grazing or hay crop. Corn yields in the piedmont are lower after small grain silage removal compared to leaving the small grain as mulch. Woollypod vetch is the earliest maturing/blooming commercially available vetch. If the legume cover crop is established early enough, adequate growth in the fall can help minimize soil erosion. Woollypod vetch can be easily grown if planted into a moist soil, in the early fall. Hairy vetch is a winter-hardy cover crop that can grow in areas that undergo a hard freeze. Raleigh, NC: Agricultural Experiment Station, North Carolina State College. Therefore, use of a soil insecticide is recommended when planting without tillage into a cover crop. Hairy vetch can become weedy if left to produce seed. Sharing the benefits of how cover crops can improve no-till farming practices through continued research, education, product development and by offering the highest quality seed and seed mixes. It has very high feed values for animals as green plants and dry matter as well as grain. Thus, they may act as a net drain rather than as a contributor of N to the system. 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. When planted alone as a winter cover crop in annual vegetable rotations, it can provide as much as 110 lbs. Legumes can supply much of the N required for many summer crops, from row crops such as corn or grain sorghum to vegetables such as sweet corn, cabbage, squash, and pumpkins (Figure 2). Plowing cover crops under early in the spring will increase the decomposition rate of the cover crop, but this early termination date also limits cover crop growth, which limits nutrient accumulation and the buildup of soil organic matter from the residue. Call to Order: We are encouraging our customers to call us at 800-352-5247 to place your orders.We can then ship your seed directly to you, or you can come pick it up at Albert Lea Seed. Rye cover crop terminated by a roller-crimper prior to planting certified organic soybeans. Hairy vetch prefers well-drained soils with a pH of 6.0-7.0, and will do poorly in clay or wet fields. For soil improvement: When sown in August, a considerable growth of rye and vetch can be plowed down the following... 2. It is essential that cover crop vegetation be thoroughly and uniformly sprayed for effective control. Several studies comparing conventional and no-till corn in eastern North Carolina have documented the potential contribution of N by legumes. Harvesting: 1. Common vetches are an annual pasture/forage/grain legume, extremely palatable at all growth stages, from early green shoots, as dry matter/hay or silage through to seedpods and seeds over summer. Winter Cover Crops: Their Effects on Corn Yields and Soil Properties. Hairy Vetch (Vicia villosa) is a short term legume commonly used for cover crops in home gardens, weed suppression, erosion control, ground cover, green manure, pasture, silage and hay. Hessian fly does not inhabit rye, triticale, barley, or oats. Seeds that have a hard seed coat can lay dormant in the soil for over five years. B: Cover crop wheat planted to protect a planned summer vegetable crop. Woollypod vetch has the potential to grow faster and earlier than hairy vetch. Figure 5. Early seeding dates are easy to meet with legume cover crops following tobacco, corn silage, spring vegetables, or, in eastern North Carolina, grain corn. However, it is also less winter hardy than hairy vetch. Another example would be the use of wheat, triticale, or barley with crimson clover. It grows slowly in the fall, but its roots grow throughout the winter and by spring, hairy vetch quickly grows into twelve-foot long vines. Mow the hairy vetch before the plant flowers in spring. Crown vetch, a perennial, spreads by rhizomes under ground as well as by seed dispersal. Generally, a grass species is combined with one or more legume species. If grown as a seed crop, hairy vetch is harvested when the lower pods are ripe to avoid shattering. 1958. Results of N response test for corn yields, Tyrrell County, 2007. One or more residual herbicides are usually applied at the same time as the knockdown herbicide. However, in a hairy vetch cover crop, increased populations of soybean cyst nematodes have been found. Hairy vetch develops best under cool temperature conditions on fertile loam soils; it is also productive on sandy or clay soils. 2. Hairy vetch is a hardy type of vetch suited to wetter soil and colder winters than other winter-active legumes. 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. Fertilizer costs vary due to market fluctuations but are generally in the range of $0.35 to $0.70/pound of N ($200 to $400/ton of 30 percent N solution). If carefully managed, hairy vetch may be grown with Bermudagrass. Raleigh, NC: N.C. Figure 1B. Individuals who use agricultural chemicals are responsible for ensuring that the intended use complies with current regulations and conforms to the product label. Timely management is required to optimize cover crop and cash crop performance. 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. A&T State University. A well-established legume cover potentially can supply 50 to 150 or more pounds of N per acre, or approximately two thirds of the N required by a corn crop and most of what is needed for grain sorghum and some vegetable crops (Table 3 and Table 5). Caesar Kleberg Wildlife Research harvested with this method is best cleaned by Institute. This vigorous, fast-growing perennial grows in 2-foot tall mounds. N.C. Due to its low C:N ratio, the plant material readily breaks down after termination. If Hessian fly is present in your area, wheat should be planted after the first fall frost. Some situations, however, require a different approach. 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). To plant hairy vetch, plow the soil as you would for any regular crop. 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. Common vetch, Vicia sativa, does not produce as much seed as hairy vetch, posing less of a risk of becoming weedy. — Read our Woollypod vetch is a cool season annual legume, comparable to many other vetches but with a few of its own unique characteristics. Cover the seeds with about ½ inch of soil, then water well. High pressure (40 to 45 pounds per square inch) will help the spray penetrate dense vegetation. This thick thatch will slow soil warming and drying and this could cause some issues in a no-till system. Woollypod vetch has been observed to survive conditions as low as 0 degrees F with no snow cover but that was without much fluctuation in the temperature. 10% - 30% vetch inclusion in a whole crop mixture with cereals and or peas. Cultipacking after broadcasting will encourage good soil/ seed contact. 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. Freeze damage has also occurred with Austrian winter pea in higher elevations (above 2,500 feet). Seed corn insects can be abundant in cover crops used as no-till mulch. If not given structure to climb, Woollypod vetch with grow across the ground forming a very thick and tangled thatch. Hairy Vetch is best grown with plants like cereal rye that enable the hairy vetch to climb up the cereal rye to allow air movement across the soil surface. I. 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). For pasture: A field of fall-seeded rye and vetch can be pastured from early May through June, then plowed and sown... 3. Proper field scouting is important in determining the need for postemergence weed control measures. Descriptions of many potential cover crop species can be found in the US Department of Agriculture publication Managing Cover Crops Profitably. It has been reported to grow … Ideal Sowing Time Be sure to obtain current information about usage regulations and examine a current product label before applying any chemical. Technical Bulletin no. Seeds may be broadcast if the soil has been disked and partially smoothed. In conservation tillage systems, the residue from the cover crop is not plowed under after the herbicide treatment and remains on the surface as mulch (Figure 1A). In the spring, if grazing continues too long, growers may find that the rough soil conditions caused by hoof traffic lessen the benefits they expected from spring no-till management. For best results, plant 3-6 weeks prior to the average first killing frost. In planting, use shallow planting depths for finer-textured, clayey soils and deeper depths for coarse-textured, sandy soils. FARM SEED SALES & PICK UP. Many farmers use smallgrain cover crops to control erosion. Rye is the easiest small grain cover crop to control with Gramoxone. A: Aerial overseeding prior to soybean leaf drop in Pamlico County. Legume and small grain cover crops under drought stress are more difficult to control. Effect of cover crop and N rate on corn grain yield (2-year average). For this reason, in milder climates it is not as vigorous as other vetches but can still give high yields if allowed to fully mature in late May. This slight yield advantage is more than offset, however, if the legume residue is left on the surface to increase infiltration of water and conserve soil moisture when dry growing conditions prevail. Figure 8. 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. A. Kranz. 1998. SmartMix is the best cover crop decision making tool in the industry. English photo. Soybeans are never harvested early enough for the seeding of legume cover crops. 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. AU Merit hairy vetch can be seeded at a rate of 10-40 lbs/acre depending on the mix or purpose. Woollypod vetch excretes root exudates that can reduce the growth of small grasses. *Based on a 1-10 scale. Use 11⁄2 to 21⁄2 pints of Gramoxone Super per acre or 11⁄2 to 2 quarts of Roundup per acre. In a wet growing season, tilling legumes into the soil may produce slightly greater yields in the crop that follows. Variation in soil temperature at 2" depth with selected cover crops. This allows establishment of the cover crop after a late-fall-harvested crop such as soybeans. As an annual legume, hairy vetch may need to be terminated either mechanically or chemically when followed by a row crop. In addition to protecting land from erosion, hairy vetch can provide spring pasture for livestock. Publication date: May 6, 2014 Crown vetch (Coronilla varia) is planted as a ground cover and grown on disturbed slopes to stop erosion. If planted to late when soils start to cool off than overall germination and results will be unfavorable. Leaving the cover crop on the surface also reduces its decomposition rate compared to plowing. Growers need to consider timing when planting winter wheat in locations where the Hessian fly may be a problem. 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. Residual weed-control methods for no-till crops planted into a cover crop are similar to those used for conventional planted crops, with the obvious exception of the use of cultivation for weed control. Managing winter-annual legumes as nitrogen sources for no-tillage corn on sandy Coastal Plain soils. Subterranean clover is a warm-weather winter cover crop, and it will typically complete … 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. It is possible to broadcast seed at 20-30 lbs/A and use a light disking or field cultivation to improve seed to soil contact. This vetch has been observed to produce more biomass than many other vetches and fixation of N could even start within a week of emergence. Kamprath, E. J., W. V. Chandler, and B. Cooperative Extension, College of Agriculture and Life Sciences, NC State University. Seedlings are especially vulnerable to damage from sandblasting during cool, dry springs, when growth rates are slow. Wind erosion can be severe in cultivated organic and sandy soils of this region (Figure 3A). In addition, the potential for conserving soil moisture may be reduced if the cover crop is removed for silage, leaving less mulch and reducing the following corn yield (Figure 8). Seed pea vetch. On coastal plain soils, supplemental N (25–35 pounds per acre) may be needed to obtain adequate top growth. Aerial seeding of rye into soybeans just before leaf drop has been marginally successful. When growing a winter rye and legume mixture, the rate of winter rye seeding should be reduced to no more than a bushel per acre to allow space for the legume to grow. * 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). Depending on the grass and legume cover crops chosen, a reduction in seeding rate may be appropriate. Planting about a quarter of your garden to cover crops each year can add fertility, reduce erosion, help break pest cycles, and much more. 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 Careful management can prevent this problem. when future price increases or supply fluctuations make N fertilizers less attractive; if farmers want to take advantage of soil physical property benefits provided by cover crop residues. Limited research indicates that these soils respond to subsoiling even with the presence of a cover crop mulch. Though not as cold tolerate as hairy vetch, it can survive in freezing conditions for several days. Managing Cover Crops Profitably. The ideal temperatures for early root growth range from 20° to 25° C (68° to 77° F). 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. Cooperative Extension. Handbook series book 9. Active cover crop growth in the spring, before the summer crop is planted, offers continued erosion control compared to bare ground. Crimson clover grows faster in the spring, thereby maturing and obtaining peak dry matter production approximately three to four weeks ahead of hairy vetch. Sorghum Sudan (Sweet Six Dry Stalk BMR) - Hybrid. With hard seed potential, seed can germinate over the course of several years and this would be a concern in fields that will be planted to a commercial cereal grain crop. Hairy vetch is a winter annual legume and one of the most productive at nitrogen fixation. It can also be used in feed as hay, silage or grazing due to its high crude protein content. Winter annual legumes can be grazed or cut for hay before the summer crop is planted. N.C. Studies have shown some tolerance to glyphosate. A newly developed alternative for certified organic farms that provides similar residue conservation without herbicides involves cover crop termination using a roller-crimper (Figure 1B). Thus, they can reduce crop growth unless sufficient inorganic N is applied (Figure 2). 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. ... Cover Crop Seed Mixtures. This field is for validation purposes and should be left unchanged. Figure 6. Known as a prolific N producer, it has the potential to fix up to 250 lbs N/A if able to overwinter from a fall planting. In contrast, rye reduced corn yields unless sufficient nitrogen fertilizer was applied. Tolerates temperatures below 0°F if planted early enough to get established, and goes dormant in cold weather making most of its growth in late spring. For both hairy vetch and Cahaba white vetch, the rates are 20 to 30 pounds per acre broadcast and 15 to 20 pounds drilled. 3. In many areas of North Carolina, nutrient management is becoming increasingly important as farmers do their part to protect surface waters from nutrient loading. All of these plants have similar heights, so deleterious shading would be at a minimum compared to using taller rye and shorter crimson clover. 7.5 - 22.5kg per acre / 18.75 - 56.2 kg per ha. Fields heavily infested with johnsongrass, bermudagrass, or nutsedge should not be planted to cover crops until adequate weed control has been achieved. NC State University and NC 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. North Carolina Agricultural Chemicals Manual. When hairy vetch, common vetch, crimson clover, and Austrian winter pea were planted in a mixture with cereal rye, spring oats, or winter wheat, the cereal rye/hairy vetch mixture had 30 to 45 percent less residual inorganic soil nitrogen than legume-only plots. AG-439-58. Harvest the seed as soon as the plants, pods and seeds are dry enough to thresh. What puts vetch in the weed category is that the hairy vetch, an annual, drops its seed early and once established it’s very difficult to eradicate. 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).
