In planting, use shallow planting depths for finer-textured, clayey soils and deeper depths for coarse-textured, sandy soils. B: Cover crop wheat planted to protect a planned summer vegetable crop. This vigorous, fast-growing perennial grows in 2-foot tall mounds. 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). Harvesting: 1. This species is really known for its climbing ability, even more so than common vetch. May have some allelopathic properties, so it is best to allow 2-3 weeks between incorporating and seeding of small-seeded crops. With a small grain cover crop, killing it seven to fourteen days before corn is planted can reduce potential soil water depletion. By combining grass and legume cover crops, farmers also can gain the benefits of nitrogen scavenging, high biomass production to build organic matter, biological nitrogen fixation, and moderated nutrient release, compared to a legume-only cover crop. However, do not delay corn planting to allow additional growth of legume cover crops. Variation in soil temperature at 2" depth with selected cover crops. 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. High pressure (40 to 45 pounds per square inch) will help the spray penetrate dense vegetation. In contrast, rye reduced corn yields unless sufficient nitrogen fertilizer was applied. However, either of these practices would remove most of the nitrogen and mulch from the system because nitrogen is concentrated in the top growth. 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. Woollypod vetch is a cool season annual legume, comparable to many other vetches but with a few of its own unique characteristics. The following general cultural practices are applicable to all legume cover crops: Planting dates. 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. Allowing the cover crop to grow until later in the spring will improve nutrient accumulation in the cover biomass, but it may reduce the ability of microbes to decompose residues for short-term use. Cultipacking after broadcasting will encourage good soil/ seed contact. 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. Hairy Vetch does an excellent job in soil tilth in the top few inches in the soil, often creating the illusion of planting in a cloud due to the soil’s looseness. Freeze damage has also occurred with Austrian winter pea in higher elevations (above 2,500 feet). 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). *Based on a 1-10 scale. by Eric Sideman, Ph.D. 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. AG-439-58. Some situations, however, require a different approach. seed will mature, but care must be taken to insure Smith, F.S., A.D. Falk, and W.R. Ocumpaugh. Timely management is required to optimize cover crop and cash crop performance. Use seed that has been inoculated with the appropriate rhizobium strain (hairy vetch/pea group Rhizobium leguminosarum biovar viceae) to guarantee nitrogen fixation. Raleigh, NC: N.C. Seedlings are especially vulnerable to damage from sandblasting during cool, dry springs, when growth rates are slow. Crimson clover grows faster in the spring, thereby maturing and obtaining peak dry matter production approximately three to four weeks ahead of hairy vetch. 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. Seeding rates and depths vary with legume species (Table 2). — Read our 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. Small grains and other grasses help control erosion caused by wind or water (Figure 3). A: Cover crop wheat planted to protect stale seed beds during the winter. 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.
