Species with similar growth forms are likely to compete with each other, while species with differing growth forms are more likely to be complementary (Figure 1). This cover crop mix contains 2 different seed varieties that work in concert to produce an abundance of green manure, weed suppression, and nitrogen fixation. For instance, legume cover crops with greater biomass and nitrogen content will supply more nitrogen, and a greater flower density in a cover crop stand will attract more pollinators. Certain species are highly competitive against other species in a mix, including forage radish, canola (Brassica rapa), oats, sorghum-sudangrass, and cereal rye. Nitro Brand™ Cover Crop Mix (Planted at 28.5 lbs./Acre.) But all the options of species to plant can be overwhelming. Start Mixing Phacelia can be sown in late summer in milder areas – or wait until spring if winters are cold where you are. Allowing legumes to grow to the flowering stage generally maximizes nitrogen accumulation of the cover crop, but allowing a legume to flower for too long can cause a decline in nitrogen content as nitrogen is transferred to maturing seeds. The selection of complementary growth periods and forms in the species of a mixture will allow for uniform termination of all species; however, several strategies exist to manage asynchrony when it arises. A final approach that has been used, which is more time and equipment intensive than other approaches, is to seed the large-seeded species to depth with a drill and then make a second pass with a broadcast seeder, broadcasting the small-seeded species onto the soil surface and then firming in the seedbed with a cultipacker. Benefits of Crimson Cover-All Mix. Forage radish provides excellent erosion control in the fall, but soil is left bare in spring after winter-killed residues decompose. Hardiness Zones: Annual cover crop use Days to Maturity: Mixed varieties, 30-70 Days Cover Crop Mix Seeding Rate: 2-4 lb per 1000 sq. Just as a cover crop mixture must meet the specific needs of a cropping system, the appropriate timing and method of termination is often specific to the cropping system. The only possibly option is to sow a flush of mustard leaves, which would give leaves for picking and then you could dig that in. Clover, White: Strong growth in cool weather, fixes nitrogen, good to mix in with other grains or intercrop with winter … Planting mixtures in one pass by splitting the species according to seed size and planting depth has been the most effective strategy at obtaining optimum seeding depths for various species in a mixture. Determine the appropriate seeding mix and planting method, being sure to keep extremely competitive species at a low seeding rate. Achieving this balance can be difficult because certain species are highly competitive, causing the desired services of the less competitive species to go unrealized. Generally the green manures you can eat - e.g. Cover crops, or green manures, are a great way to protect ground that would otherwise lie bare over winter. Easy-to-manage cover crop. Use a spade or hoe to dig out trenches about two inches (5cm) deep. It combines the deep rooting of the ryegrass, the scavenging action of the radish, and the nitrogen production of the clover to produce a great crop growing environment. However, management of the cover crop before seed set or a plan to manage "volunteer" cover crops resulting from those that set seed should be in place before allowing cover crops to flower. Dig the cover crop into the ground at the end of winter and it will rot down to add valuable organic matter, helping to feed the plants that follow. Rapid growth of the winter-killed species in the fall will increase nitrogen uptake, weed suppression, and erosion control in the fall. Illustrated in Figure 2 are some of the important points about achieving good weed suppression with cover crop mixtures. Cool-season species with winter annuals are used from mid-August through October. Identify the top three desired cover crop services for a specific field or farm. This approach sometimes works, and it may be the only solution for drills with a single seed box. $3.50 - $9.95. However, under a different management approach, maintaining a longer flowering period before terminating the cover crop may be desired to provide resources to beneficial insects. Fall/winter cover crop mix seeding - posted in Cover Crops and Related: I have read everything I could find and am now sold on the cover crop concept for our pastures for the next several years. Generally, cover crops in organic systems can be terminated with various combinations of a moldboard plow, flail mower, disc, and/or cultimulcher. Purchasing Cover Crop Seed When purchasing cover crop seed, choose cover crop species adapted to local growing conditions (Bodner et al. Cover crops also help to reduce erosion and can even prevent weeds! SPRING COVER CROP MIX Our Spring/Summer Base Cover Crop mix is a blend of cowpeas/mungbeans, sorghum sudan, broadleaf forages and legumes to fill a dual purpose role of providing nutritional and economical grazing as well as being a soil builder. Under nitrogen-deficient conditions, canola growth is limited (C), reducing its weed suppression compared to canola with sufficient nitrogen available (G). In a drill with one seed box, vertical baffles between openers, spanning front to back of the drill box, can be created with cardboard and duct tape. We planted the same four-species cover crop mixture (cereal rye + canola + Austrian winter pea + red clover) at farms in different counties across Pennsylvania to observe how the mixture performed. One way to buffer against the loss of a desired service is to increase redundancy in the mix with additional species that perform the same functions or exhibit similar growth characteristics. Grow cover crop garden heirlooms from seed such as annual Austrian Field Pea, Hard Red Winter Wheat, Triticale, Daikon Radish, and more. We start wiht cool-season species for the early spring planting dates of March through April. Fall cover crop mix is a ready-to-sow green manure perfect for renewing soils. Late Summer or Early Fall Plant. A legume cover crop planted in a soil with high nitrogen levels will grow well, but it will be less competitive against nitrogen-hungry weeds and not prevent nitrogen leaching as well as a nonlegume would. I’ve just cleared my garlic plot and would like a recommended green manure. Total cover at 30 days after planting (DAP) averaged 62% for all of the cover crop mixes, which was almost twice that of the weedy control at only 35% cover (Figure 1). Planting date recommendations from Cover Crop Solutions, LLC, when available and personal experience otherwise. Characteristics, ability to provide various services, and recommended planting date windows for nonlegume winter cover crops commonly used in temperate cropping systems.

For soils with excessive nitrogen levels, nonlegumes that are aggressive at scavenging soil nitrogen should be used. This means we can work Watch the cover crop growth and be sure to terminate at the right time. In some cases, excessive biomass production by species in a mixture can lead to challenges for cover crop termination and incorporation and for planting the following crop, as well as reduce the efficacy of other species in the mix. Winter field beans are always a good one for overwintering - very hardy and would be dug in before you need to plant in April/May. To sow a cover crop, start by roughly digging the ground over. In some cases, excessive biomass production by species in a mixture can lead to challenges for cover crop termination and incorporation and for planting the following crop, as well as reduce the efficacy of other species in the mix. Fall cover crop mix is a ready-to-sow green manure perfect for renewing soils. On the disc opener of this grain drill, the tube from the small seed box (smooth tube) deposits seed behind the disc opener for shallow seed placement. Nationwide distributors of cover crop seeds, forages, biological and custom seed mixes. Use cover crops to build organic matter, fix nitrogen, draw nutrients from the soil, prevent erosion, and break pest and disease cycles. These resources are all vital in supporting predatory and parasitic insects and spiders. Alternating row configurations can easily be sown in one pass using a drill with two seed boxes. For other considerations when providing resources to promote natural enemies, such as optimal distances between insectary strips and crop fields, see the eXtension article "Farmscaping: Making Use of Nature's Services.". Nitrogen released rapidly following winter-kill of these species is subject to leaching losses. Tour of cover crop demonstrations plots.

Read on or watch our video to discover exactly how to do it. longipinnatus) can suppress weeds and reduce compaction in the fall, but because it winter-kills, it does not provide a living root system or residue cover in the spring. At Green Cover Seed, we went beyond the three sisters and compiled a mix of over 40 different seeds. If providing resources for conserving pollinators and other beneficial insects is desired, differences in flower morphology such as shape, size, and color will influence the types of beneficial insects that are attracted to a particular cover crop. Adaptive management based on rainfall patterns and cover crop growth is crucial to optimize cover crop water use and retention. Cover Crops Cover cropping is a cost effective way to improve your soil. (Refer to Tables 1 and 2 as needed.) Why do we need this? Make sure to research the best cover crops to use if your farm or fields struggle with pest infestations. However, not all cover crop species provide the same benefits. N-Vest ® Forager Mix is a combination of Oats, Winter Rye, and Turnips. Prolific salads such as mache or corn salad may also be grown this way. “Cereal rye was the only crop to consistently survive over the winter in our trials.” Single vs. Mustard is a particularly good cover crop for clay soil, where it can be dug in before winter so frosts have a chance to break the soil up. This dynamic tradeoff between grasses and legumes allows the cover crop to adapt to the nitrogen management service needed most. For example, in Northeastern organic reduced-tillage systems, studies found that cereal rye/hairy vetch mixtures often required multiple roller-crimper passes to prevent seed production because of differences in the maturity timing of each cover crop (see Cover Crop Rollers for Northeastern Grain Production ). The flowers are stunning and a major draw for bees and hoverflies, so consider leaving a small patch to flower to attract them. Combined, Bill and James have 12 years of experience growing cover crops. When species with different seeding depths are mixed together, there are several strategies that can be used to aid in successful establishment of each species. Figure 4. Shepherd Seeds is an independent small grain seed specialist based Lincolnshire. Applying this idea to cover crop mixtures, we expect that selecting a small number (three to five) of complementary species and managing them to achieve even biomass production in the mixture will provide multiple cover crop functions. Our mix designs follow the seasons in which you choose to seed the cover crop. Below are our recommendations of fall-winter cover crop. Allowing species such as hairy vetch (Vicia villosa) or canola to flower for too long may also result in viable seed set, possibly creating an undesirable seed bank in the soil. Add your own thoughts on the subject of this article: Over the years we have developed and modified cover crop seed mixes for specific goals that many producers have in common, serving as proven solutions. If any have severe drawbacks, drop that species from the mix. As nitrogen availability decreased, the presence of Austrian winter pea in the mixture increased. The e-mail does not appear to be correct. Customized cover crop mixes can be valuable on your operation. When seeded in the summer, red clover is slow to establish and prone to weed invasions. Alternatively, another example could be to switch the grass in your mixture from cereal rye to a later maturing grasslike triticale (x Triticosecale), wheat (Triticum aestivum), or spelt (Triticum spelta)--thus increasing the likelihood of synchrony between the cover crops in the mixture and reducing nitrogen immobilization that could occur from the incorporation of highly lignified stems. Penn State College of Agricultural Sciences. By tailoring the selection of cover crop species to meet farm management objectives, understanding complementarity between species, and following some basic management guidelines, an endless array of cover crop mixtures can be designed and implemented in any farming system.
