How long do alfalfa roots grow?
Deep-Rootedness—alfalfa roots are commonly 3-5 feet deep and can extend to 8-15 feet in some soils.
How deep does alfalfa need to be planted?
Control seeding depth. Plant alfalfa seeds three-eighths of an inch below the soil surface. In corn, precision planting is focused on seed spacing. Precision planting for alfalfa means controlling seeding depth. The goal is to establish a minimum of about 30-35 plants per square foot at the end of establishment season.
How much space does alfalfa need?
Since alfalfa roots quickly, it doesn't require deep planting—only about a half inch (1 cm.) deep. Merely sprinkle the seeds evenly onto the soil and cover lightly with dirt. Use about ¼ pound of seeds per 25 square feet and space rows about 18 to 24 inches (46-61 cm.).
Is alfalfa good for soil?
But, alfalfa also plays an essential role in soil sustainability. Not only does alfalfa help prevent soil erosion, but it also protects and improves the soil with its protective canopy, deep root system, and ability to fix atmospheric nitrogen.
What month do you plant alfalfa?
Spring alfalfa should be planted from early April to early May. The month of choice for planting spring alfalfa is April. The crop can be planted into May in irrigated situations. While planting alfalfa in the fall increases the amount of forage produced the first year, planting alfalfa in the spring is less risky.

A: Yes, alfalfa is a perennial and will grow back every year as long as it receives the proper care. Overall, it is an easy crop to grow.
What happens if you don't cut alfalfa?
Once your alfalfa does receive enough rain for regrowth it might regrow a little faster if it's cut, but it also will regrow following sufficient rain without cutting. In most cases, it's not worth the cost and time involved to shred, clip, or harvest low-yielding hay.
What do you plant after alfalfa?
The best rotational crops following alfalfa are cereal crops and annual forage grasses. Small grains can benefit from nitrogen released after alfalfa is plowed. Corn and sorghum could also follow alfalfa in those areas where rainfall is adequate or where irrigation is available.
Is alfalfa invasive?
Alfalfa has been cultivated for forage worldwide. Alfalfa may become weedy or invasive in some regions or habitats and may displace desirable vegetation if not properly managed. This species generally occurs as a weed in wildland areas of the Southwestern Region rather than as an invasive plant.
Do alfalfa pellets attract rats?
Alfalfa is particularly appealing to small animals like rabbits, and also juvenile game birds like quail and wild turkeys, who require both cover and sustenance. Therefore, if alfalfa is abundant, rats, mice, voles, and rabbits will all consume it, and consistent usage of alfalfa may boost rodent numbers in the garden.
Will alfalfa reseed itself?
Alfalfa is a crop that naturally tends to lessen its density over time because alfalfa doesn't reseed itself. Planting more alfalfa into current alfalfa fields is not recommended since alfalfa has autotoxicity characteristics. A good population/density is about 35 well-growing stems per square foot.
Does alfalfa fix nitrogen in soil?
Alfalfa fixes more nitrogen than any legume crop. In fact, a stand can fix as much as 300 pounds of N per acre per year. It uses much of this nitrogen to produce protein in the plant, which growers can harvest and feed to livestock.
How long does Alfalfa live?
Alfalfa is a perennial forage legume which normally lives four to eight years, but can live more than 20 years, depending on variety and climate. The plant grows to a height of up to 1 metre (3 feet 3 inches), and has a deep root system, sometimes growing to a depth of more than 15 m (49 ft) to reach groundwater. Typically the root system grows to a depth of 2–3 m (7–10 ft) depending on subsoil constraints. Owing to this deep root system, it helps to improve soil nitrogen fertility and protect from soil erosion. This depth of root system, and perenniality of crowns that store carbohydrates as an energy reserve, make it very resilient, especially to droughts. Alfalfa has a tetraploid genome.
What is the alfalfa plant?

Alfalfa usually has the highest feeding value of all common hay crops.
Why is alfalfa considered an insectary?
Alfalfa is considered an insectary, a place where insects are reared, and has been proposed as helpful to other crops, such as cotton, if the two are interplanted, because the alfalfa harbours predatory and parasitic insects that would protect the other crop. Harvesting the alfalfa by mowing the entire crop area destroys the insect population, but this can be avoided by mowing in strips so that part of the growth remains.
What is the name of the bales used to wrap alfalfa?
After the alfalfa has dried, a tractor pulling a baler collects the hay into bales. Several types of bales are commonly used for alfalfa. For small animals and individual horses, the alfalfa is baled into small, two-string bales, commonly named by the strands of string used to wrap it.

What is the best crop to plant with alfalfa?
Planting alfalfa with a complementary crop, such as annual ryegrass, oats, barley, or triticale can help to minimize competition with weeds during establishment.

How to plant alfalfa in grass sod?
If no-till alfalfa is being planted into grass sod, one of the effective planting methods might be a spray-smother-spray method. First, spray the growing grass sod with a non-selective herbicide.

Does alfalfa need liming?
Alfalfa does well on well-drained soil rather than wet, heavy clay soils and requires good soil pH ranging from 6.5 to 7.0. If your soil pH is lower than 6.5, symbiotic nitrogen fixation may not function properly. Thus, liming will be required to raise low soil pH to its optimum level and make better nutrient uptake.

History
Alfalfa seems to have originated in south-central Asia, and was first cultivated in ancient Iran. According to Pliny (died 79 AD), it was introduced to Greece in about 490 BC when the Persians invaded Greek territory. Alfalfa cultivation is discussed in the fourth-century AD book Opus Agriculturae by Palladius, stating: "One sow-down lasts ten years. The crop may be cut four or six times a year ... A jugerum of it is abundantly sufficient for three horses all the year ... It may be gi…

Some pests, such as the alfalfa weevil, aphids, armyworms, and the potato leafhopper, can reduce alfalfa yields dramatically, particularly with the second cutting when weather is warmest. Spotted alfalfa aphid, broadly spread in Australia, not only sucks sap but also injects salivary toxins into t…
Harvesting
When alfalfa is to be used as hay, it is usually cut and baled. Loose haystacks are still used in some areas, but bales are easier for use in transportation, storage, and feed. Ideally, the first cutting should be taken at the bud stage, and the subsequent cuttings just as the field is beginning to flower, or one-tenth bloom because carbohydrates are at their highest. When using farm equipment rathe…
