Green Manure Cover Crop

DescriptionGreen Manure Cover Crop Mixture  Our Green Manure Cover Crop mix serves a multifaceted role in soil improvement and agricultural sustainability. Here’s an informative breakdown of its benefits and best practices for utilization:Versatile Use: This cover crop mix can be employed in two key seasons – either as a late-season and winter cover crop or as a short-lived spring cover crop.Soil Enhancement: When planted, it fosters vigorous growth that not only loosens the soil but also enhances drainage capabilities. This is especially valuable in areas where soil compaction is a concern.Erosion Control: During the winter months, this cover crop serves as an effective erosion control measure, preventing soil loss due to harsh weather conditions.Nutrient Enrichment: One of its primary advantages lies in its ability to add essential nitrogen, nutrients, and organic matter to the soil. This enriches the soil’s fertility and overall health, promoting better crop growth in subsequent seasons.Weed Suppression: By covering the soil, this mix helps control weed growth, reducing competition for nutrients and sunlight.Ideal Planting Time: For optimal results, consider planting this mix in orchards, vineyards, or in crop rotation with vegetables and field crops. Timing is crucial – aim for early spring or a window from mid-September to October (15-45 days before the first frost) to ensure the crop establishes itself before freezing temperatures set in.Pollinator-Friendly: The vetches in this mix serve a dual purpose as they are excellent pollinator plants. They attract honeybees and beneficial predatory wasps, contributing to overall ecosystem health.Sowing Rate: To achieve the best results, sow the Green Manure Cover Crop mix at a rate of approximately 1 pound per 500 square feet.Winter Hardiness: The mix includes winter rye, oats, vetches, and Austrian Peas, all of which are winter-hardy. They continue to grow even in near-freezing temperatures, forming a robust network of roots and sturdy stalks that enhance the soil’s organic matter.Fertilizer Reduction: Thanks to the nitrogen-fixing properties of vetches and Austrian Peas, you’ll find that you need less supplemental fertilizer when using this mix, reducing your environmental impact.Maintenance: To prevent volunteer plants from sprouting up in the next season, it’s advisable to mow or incorporate (till under) the crop after flowering, but before seed production. Aim to till under about one month before you plan to plant your main crops.In summary, the Green Manure Cover Crop mix isn’t just a cover crop; it’s a strategic tool for soil enhancement, erosion control, and sustainable agriculture. Its careful selection of winter-hardy components and nitrogen-fixing plants makes it an invaluable addition to your farming or gardening practices. Green Manure Cover Crop Mix Seeding Tips:Contents:  (inoculated)                                                               Percent               Nitrogen accruement* Austrian Winter Peas    Pisum sativum subsp. arvense               30%                    3.3 lbs/1000 sq. ft.

This video from “Gardens That Matter” explains the basics (the why, when, and how) of cover crops.“When fresh plant material decomposes in the soil, its carbon-to-nitrogen ratio becomes low, allowing the nitrogen to be easily released into the soil chemistry by bacteria. Nitrogen accumulation is greater with legumes, which have nitrogen-fixing Rhizobium bacteria growing in nodules on the legume roots.Microorganisms decompose plant material and the plant material itself produces substances that glue soil particles together. These substances include slime, mucus, and fungal mycelia, which contain gums, waxes, and resins. They aggregate soil particles, thereby enhancing the tilth, porosity, and water holding capabilities of the soil.”Source: Colorado State University – CMG Garden Notes #244
