What is the main purpose of a cover crop?

A cover crop slows the velocity of runoff from rainfall and snowmelt, reducing soil loss due to sheet and rill erosion. Over time, a cover crop regimen will increase soil organic matter, leading to improvements in soil structure, stability, and increased moisture and nutrient holding capacity for plant growth.

Why do farmers grow cover crops?

Cover crops help prevent soil erosion, regulate moisture, attract pollinators, assist in weed and pest management, serve as mulch and the source of green manure and organic matter, and are used for grazing or forage. Depending on the types of cover crops, they add or uptake nitrogen.

What are cover crops and why are they grown?

In agriculture, cover crops are plants that are planted to cover the soil rather than for the purpose of being harvested. Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosystem—an ecological system managed and shaped by humans.

What are the disadvantages of cover cropping?

A cover crop disadvantage for commercial farmers is cost. The crop must be planted at a time when labor as well as time is limited. Also, there is the additional cost of planting the cover crop and then tilling it back under which means more labor.

Can I eat cover crops?

Forage radish, rape (or Canola), and sugar beets are other non-legume cover crops that can be eaten. So far all of the cover crops mentioned have been grown as annuals, that need to be replanted each year. A couple of perennial plants that can be used as edible cover are pigeon peas and moringa.

How are cover crops used to improve soil fertility?

Cover crops are able to increase soil organic matter by protecting the soil surface from erosion, adding biomass to the soil (especially below the soil surface), and creating a habitat for microorganisms like fungi that contribute to the soil biology and provide more pathways for nutrient management in the soil ...

What do you do with cover crops in the spring?

Cover Crop Removal

Till both expired and living crops into the soil 3 to 6 weeks before spring planting⁷, making sure you till living crops before they produce seeds. The best time to add soil amendments is after removing fall crops, when the soil is bare.

Do you harvest cover crops?

After they have grown, cover crops are not harvested but instead tilled into the soil, where their nutrients can then benefit the garden. To do so, cut the cover crop in the spring a few weeks prior to planting your garden.

What is the fastest growing cover crop?

These fast-growing crops are used primarily to suppress weeds and add organic matter. Common choices are sudangrass (or sorghum-sudangrass) and buckwheat. Both grow rapidly if there is sufficient warmth, moisture and fertility.

Will deer eat cover crop?

Deer may browse on many of the species planted as cover crops. ... Small mammals such as rabbits, field mice and voles can feed on cover crops and any seeds they produce.

Which is strip farming?

Strip cropping is a method of farming which involves cultivating a field partitioned into long, narrow strips which are alternated in a crop rotation system. It is used when a slope is too steep or when there is no alternative method of preventing soil erosion. ... The forages serve primarily as cover crops.

What is a good summer cover crop?

Buckwheat is usually the star of summer cover crops, taking just 30 days to start bringing benefits to your soils. It's a great option for those without a plan, especially if soil is left bare after a harvest with no planned succession.

What is no-till cover crop?

In no-till cover crop systems, the known benefits of cover crops are maximized by allowing them to grow until shortly before planting the vegetable or other cash crop, and by managing the cover crop without tillage. ... they die down naturally in time to plant summer vegetables.

Which crops improve soil fertility?

Whether grown as pulses for grain, as green manure, as pastures or as the tree components of agro-forestry systems, a key value of leguminous crops lies in their ability to fix atmospheric nitrogen, which helps reduce the use of commercial nitrogen fertilizer and enhances soil fertility.

Do cover crops help with compaction?

Deep-rooted cover crops can provide a less costly and longer-lasting solution to compaction issues. A four-year research study on soil compaction at Ohio State University showed that soils compacted with a 20-ton grain cart yielded better when soybeans were grown after cover crops compared to using annual subsoiling.

What is contouring in farming?

Contour farming is the practice of tillage, planting, and other farming operations performed on or near the contour of the field slope. ... Tillage and planting operations follow the contour line to promote positive row drainage and reduce ponding.
