Determining the optimum maturity stage to terminate cover crops can be challenging because it often involves tradeoffs among the different benefits provided by cover crops. The suggestion has been made that in a mixture the larger-seeded species planted to such a depth will break open the seed furrow as they germinate and allow the smaller-seeded species to then emerge. Some species have narrow or restricted seeding windows in the fall to achieve successful establishment. In soils with moderate nitrogen levels, a mixture of a legume and nonlegume can work well, as the nonlegume will take up the soil nitrogen, protecting it against leaching, while the legume fixes nitrogen from the atmosphere, adding nitrogen to the plant-soil ecosystem. This mix contains broadleaf and grass species, providing diversity and a balanced diet for livestock. It is important to remember that cover crops can host crop pests, serving as a "green bridge" between cash crops. Use a hand broadcaster to sow 2.5 lbs of Winter Mix seed per 1,000 sq ft of soil. Thanks. The starting point for developing mixtures is understanding the strengths and weaknesses of individual cover crop species. Cool-season species with winter annuals are used from mid-August through October. Nutribuilder is a three way mix of annual ryegrass, crimson clover, and cover crop radish.

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. Fall Green Manure Mix: A blend of winter-killed and winter-hardy cover crops. The tube from the large seed box (corrugated tube) deposits seed at the front of the disc opener for placement at the bottom of the furrow. Figure 1. Navigating the maze of complementary growth periods is a sure way to hone down the list of cover crop species that will perform well together in a mix. WINTER WHEAT WINTER WHEAT. These are all types of legume and are a great choice for sowing before nitrogen-hungry brassicas such as cabbage.

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. Because forage radish has the tendency to outcompete other species in a mix, segregating the radishes and companion species into different rows allows the companion species to establish. For example, if a mixture of cereal rye and red clover is allowed to mature for too long, then the cereal rye can become excessively lignified, potentially leading to nitrogen immobilization in the following cash crop. The small box, sometimes called the legume or grass-seed box, is optimized for small-seeded crops. These factors, amongst many others, help nutrient availability, water holding capacity and weed suppression. Combined, Bill and James have 12 years of experience growing cover crops. Figure 4. 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.

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.". 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. Although legumes can take up soil nitrogen, they do so less aggressively than grasses and brassicas.
