You can usually reduce your nitrogen fertilizer inputs following a legume, but they are not very good at scavenging nitrogen that is left over after your cash crops. Cover crops take very little labor while also adding organic material to your soil. Because each root of the cover crop creates pores in the soil, cover crops help allow water to filter deep into the ground. In organic no-till farming, use a roller-crimper to kill the cover crop and leave the mulch on the soil surface to conserve water. Cover crops: Cover crops are an important part of sustainable agriculture. Kaspar, Thomas, et al. Although seeding and management of cover crop mixes or “cocktails” can become more complicated, planting them allows you to attain multiple objectives at once. There are many benefits the permaculture gardener can get from using cover crop planting. Cover crops can help improve soil quality, save manure nitrogen or fix nitrogen for the following crop, supply rescue forage and can lead to improved ground and surface water quality. Compared to pure stands of legumes or non-legumes, cocktails usually produce more overall biomass and nitrogen, tolerate adverse conditions, increase winter survival, provide ground cover, improve weed control, attract a wider range of beneficial insects and pollinators, and provide more options for use as forage. Cover crops enhance biodiversity on the farm and contribute to a healthier ecosystem in many ways. What is a Cover Crop? In the drought year of 2012, farmers reported even greater yield increases when they used cover crops: 9.6% in corn and 11.6% in soybeans.

Better synchrony of cover crops with crop insurance programs (since it is widely known that this can be a challenge for producers and that conservation can reduce climate risks!) Provide nutrients to the soil, much like manure does. In Michigan, for example, some potato growers report that two years of radish improves potato production and lowers pest control costs. 1918-1928., doi:10.1094/PDIS-07-16-1067-RE. The cover crop mulch can increase water infiltration and also improve moisture availability by preventing evaporation. Do you want to add nitrogen to your soil, increase organic matter to improve soil health, reduce erosion, provide weed control, manage nutrients, and/or conserve soil moisture? Cover crops are also called "green manure" and sometimes "living mulch." Winter cover crops help hold soil in place over the winter and provide ground cover. The yield benefit is often apparent after just one year of using cover crops, and farmers will start to see other benefits, such as improved soil health, after several years of using them in crop rotation.

Find out more information about cocktails and cover crop mixes in the Grass/Legume Mixes chapter of Managing Cover Crops Profitably. The roots of cover crops also provide structure to the soil to prevent compaction from the weight of snow and beating rains. It also gives weeds less opportunity to establish, meaning cleaner beds for sowing or planting in spring. This is a visible reminder that growing a food crop consumes considerable organic matter. To learn more about non-legume cover crops, read the Overview of Non-Legume Cover Crops section of Managing Cover Crops Profitably or consult with local expertise. Cover crops maintain and improve soil fertility in a number of ways. Cover crop cocktails, a mixture of several species and plant types, provide different rooting patterns and varying plant architecture to add diversity to the system. For resources on this subject, read the results of SARE-funded resesarch on the No-Till page of this topic room. Scroll down for further resources. Cover crop mixtures offer the best of both worlds by combining the benefits of grasses and legumes, or using the different growth characteristics of several species to fit your needs. Learn how you can use cover crops to slow erosion, boost soil health, scavenge and hold nutrients, improve water quality, and control pests, weeds, and diseases. Cover crops add organic matter to the soil, and add nitrogen in a slow-release way that plants can handle, leading to less nitrogen volatilization (read: waste! Improve biodiversity by increasing the variety of species in a given area. Protection against soil loss from wind and water erosion is perhaps the most obvious soil benefit, but providing organic matter is a more long-term and equally important goal. The SARE bulletin Cultivating Climate Resilience on Farms and Ranches has more information on the role of soil health in climate risk management. Is it too wet in the spring? Cover crops are commonly used to suppress weeds, manage soil erosion, help build and improve soil fertility and quality, control diseases and pests, and promote biodiversity.. The main objective of the study was to evaluate how the addition of a summer cover crop affects the subsequent winter pasture production in either a tillage or no-tillage system. This site is maintained by SARE Outreach for the SARE program and is based upon work supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, under award No. Cover Crops.

Let’s begin our discussion with the cover crop. Cover Crops – sometimes called green manures – are plants that are used primarily to help improve a location, primarily because of the advantages they bring to the soil. Non-legume cover crops include the cereals (rye, wheat, barley, oats, triticale), forage grasses (annual ryegrass) and broadleaf species (buckwheat, mustards and brassicas, including the forage radish).

Cover crops are typically grasses or legumes but may be comprised of other green plants. Most often, a cover crop is grown in the off-season before the field is needed for growing the cash crop. In essence, a cover crop readies the land for an incoming cash crop. See more. If a legume fits your cover crop objectives, seek additional information in the Overview of Legume Cover Crops section of Managing Cover Crops Profitably or with local expertise to identify the best ones for your conditions. The amount and availability of nutrients from cover crops will vary widely depending on such factors as species, planting date, plant biomass and maturity at termination date, residual soil fertility, and temperature and rainfall conditions. You will, of course, use different varieties for best results. A cover crop is a closely-grown crop that grows to reduce soil erosion, improve soil texture and increase water availability rather than for the purpose of being harvested. A cover crop is a plant that is used primarily to slow erosion, improve soil health, enhance water availability, smother weeds, help control pests and diseases, increase biodiversity and bring a host of other benefits to your farm. Grasses – Rye, Wheat, Barley, Oats, Sorghum, Corn, etc. Planting radishes will: • Retain soil moisture • Reduce erosion • Reduce soil compaction • Add organic material to the soil • Root channels allow for the soil to dry out and warm up faster in the spring • Reseeds if allowed. Cover crops should be viewed as a long-term investment in improved soil health and farm management. Since the early 1900s, farmers have used cover crops to restore fertility to worn-out land.

Determining when cover crops pay for themselves is not as simple as comparing the added first-year costs with the return on the following crop. When planted as a fall cover crop, non-legumes consistently take up 30-50 pounds of nitrogen per acre. “Coarse And Fine Root Plants Affect Pore Size Distributions Differently.” Plant Soil, vol. By stimulating biological activity in the soil, cover crops planted on a large scale can sequester huge amounts of atmospheric carbon. Find examples of farmers using cover crops to combat insect pests and weeds in the Pest Management section of this topic room. Cover crops are tilled under in late winter or early spring. Cover crop residue helps control weeds, which is especially important in organic no-till agriculture. A cover crop is any plant grown for the primary purpose of improving the soil. The huge roots can penetrate compacted subsoil, and when the plants die from cold temperatures, the rotting radishes improve the soil. There is an increasing body of evidence that growing cover crops increases resilience in the face of erratic and increasingly intensive rainfall, as well as under drought conditions. If you use no-till farming, the cover crop mulch increases water infiltration and conserves moisture into the summer. However, cocktails often cost more, can create too much residue, may be difficult to seed and generally require more complex management. One of the biggest challenges of cover cropping is to fit cover crops into your current rotations, or to develop new rotations that take full advantage of their benefits.
