How to grow Cool Season Annual Cover Crops (Fall)?

The cool season Cover crops are generally grown over the winter to protect the soil. They create a dense mat of roots that prevents soil erosion and absorbs soluble nutrients so they don’t leach away during winter rains. They also produce a considerable amount of organic matter, which improves soil fertility.
Some cool season crops are also grown during the growing season, when they are more commonly known as [green manure]. These add soluble nitrogen and organic matter to the soil, keep it covered (bare soil is easily damaged) and prevent the growth of weeds. If allowed to flower, many [cover crops] will also feed wildlife (especially pollinators) and increase biodiversity.
The nitrogen-fixing leguminous [cover crops] usually require an [inoculant]. Check with the seed company to see if you need to [inoculate] your seed; they will usually sell you both as a package deal.

Cool Season Annual Cover Crops (Fall) History
[Annual] [Cover Crops] are used to cover bare soil, to prevent it being damaged by the elements and to improve its fertility. They give us an easy way to maintain ideal growing soil for plants.
Soil Preference
Most cover crops are not too fussy about soil, as they have been selected for vigorous growth almost anywhere. If your soil is unusually [acidic] you may want to add [lime].
How to care for Cool Season Annual Cover Crops (Fall)?
Cover crops are very independent plants and don't require much care apart from watering. Since you'll be mostly growing them in winter, they don't usually require watering. Keeping the soil moist during [germination] is important though.
If you find that birds are eating the seeds you've planted, trying covering the beds with [row covers].
Generally you will incorporate the plants into the soil before they flower.
Water
Most of these crops are not particularly drought tolerant and will need regular watering in dry climates (especially when germinating and getting established). However they are mostly grown during the winter when the soil is fairly moist, so don't usually require much irrigation.
Fertilizer
You do not need to fertilize [cover crop] in established gardens, as there will be plenty of nutrients in the garden to meet their needs. Since you will be incorporating them back in to the soil, growing them doesn't remove any nutrients from the soil.
The leguminous cover crops also fix [nitrogen] and eventually add it to the soil.
Seeds
Seed Viability:
Light
Sun: min. 6 hours daily
Cover crops need full sun when growing in winter, as days are shorter and the sun is lower in the sky. If grown in summer many will tolerate light shade (though they grow best in full sun).
Conditions:Cold, Cool
Season:Short Season
Problems
Winterkill
If you plant too late in the fall your plants may not be hardy enough to make it through the winter. Of course this also depends upon your climate and the cover crop grown (each species has a different susceptibility to cold).
Cool Season Annual Cover Crops (Fall) Types
- Common Vetch
- Canola/Rapeseed
- Clover
- Hairy Vetch
- Fava Beans
- Austrian Winter Pea
- Oats
- Mustard
- Cool Season Blends
Common Vetch accumulated nitrogen in the soil, is frost hardy, and does not produce hard seeds. For this reason it makes for a great [cover crop] to grow over the winter.
Canola is a [cover crop] in the Mustard family that has been widely adapted for cool temperatures typical in temperate climates. [Brassica] cover crops are best used for erosion control and pest management. Canola is prone to all the same diseases as other Brassicas. Although it does not fix nitrogen, it is a good source of biomass when incorporated into the soil.
Often used in landscaping and erosion control for its beauty, cold and shade tolerance, and reseeding ability. Clover blocks out weeds and produces an abundance of organic matter when tilled into the soil. Fixes [Nitrogen], and is used as a [cover crop] in grain rather than row crop rotations because it matures late. Also good for pastures and can easily be overgrazed.
Best of all vetches for cold climates. Hairy Vetch--also called Sand Vetch--tolerates temperatures below 0° F if planted early enough to get established, and goes dormant in cold weather making most of its growth in late spring.
Cool Season Annual [Cover Crops] are planted in fall to protect the soil over the winter and produce an abundance of organic matter in spring. Fava Beans, also known as Bell Beans, are a superb [nitrogen fixer] and add lots of [organic matter] to the soil. The beans are also edible, but the plants are usually tilled into the soil before they are harvestable.
Sometimes called "black pea" or "field pea," Austrian Winter Peas are a great cool season annual [cover crop] that is planted in fall to protect the soil over the winter and produce an abundance of organic matter in spring. Because it's a member of the legume family, it is extremely efficient at fixing [nitrogen].
Cool Season Annual [Cover Crops] are planted in fall to protect the soil over the winter and produce an abundance of organic matter in spring. Oats are a cool season, annual cereal grain. They can be used for increasing organic matter, livestock feed, as a nurse crop for legumes and in areas where they winterkill-as a smother crop against weeds.
This fast growing plant has a tremendous root system and is commonly used to open up heavy or compacted soils.
There is a potential problem in using mustard as a cover crop and that is because it is a member of the cabbage family (Brassicaceae). This means it can act as a winter host for various cabbage pests and diseases, enabling them to survive the winter.
