Description

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.¹ The plant grows to a height of up to 1 metre (3+1⁄2 feet), 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.²

Alfalfa is a small-seeded crop and has a slowly growing seedling, but after several months of establishment, it forms a tough "crown" at the top of the root system. This crown contains shoot buds that enable alfalfa to regrow many times after being grazed or harvested.

Alfalfa has a tetraploid genome.³

Etymology

The word alfalfa is a Spanish modification of the Arabic word الفصفصة al-faṣfaṣa.⁴⁵

Ecology

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.⁶ 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.⁷

Owing to its deep root system, it helps to improve soil nitrogen fertility and protect from soil erosion.⁸ This depth of root system, and perenniality of crowns that store carbohydrates as an energy reserve, make it very resilient, especially to droughts.

This plant exhibits autotoxicity, which means it is difficult for alfalfa seed to grow in existing stands of alfalfa.⁹ Therefore, alfalfa fields are recommended to be rotated with other species (for example, corn or wheat) before reseeding.¹⁰ The exact mechanism of autotoxicity is unclear, with medicarpins and phenols both seeming to play a role.¹¹ Levels of autotoxicity in soil depends on soil type (clay soils maintain autotoxicity for longer), cultivar and age of the previous crop. A soil assay can be used to measure autotoxicity.¹² Resistance to autotoxicity also varies by cultivar, a tolerant one being 'WL 656HQ'.¹³

Pests and diseases

Main article: List of alfalfa diseases

Like most plants, alfalfa can be attacked by various pests and pathogens. Diseases often have subtle symptoms which are easily misdiagnosed and can affect leaves, roots, stems and blossoms.¹⁴

Some pests, such as the alfalfa weevil, aphids, and potato leafhopper,¹⁵ can reduce alfalfa yields dramatically, particularly with the second cutting when weather is warmest.¹⁶ Spotted alfalfa aphid, broadly spread in Australia, not only sucks sap but also injects salivary toxins into the leaves.¹⁷ Registered insecticides or chemical controls are sometimes used to prevent this, and labels will specify the withholding period before the forage crop can be grazed or cut for hay or silage.¹⁸ Alfalfa is also susceptible to root rots, including Phytophthora, Rhizoctonia, and Texas root rot.¹⁹²⁰²¹ Alfalfa is also susceptible to downy mildew caused by the oomycete species Peronospora aestivalis.²²

Cultivation

Alfalfa is widely grown throughout the world as forage for cattle, and is most often harvested as hay, but can also be made into silage, grazed, or fed as greenchop.²³ Alfalfa usually has the highest feeding value of all common hay crops. It is used less frequently as pasture.²⁴ When grown on soils where it is well-adapted, alfalfa is often the highest-yielding forage plant, but its primary benefit is the combination of high yield per hectare and high nutritional quality.²⁵

Its primary use is as feed for high-producing dairy cows, because of its high protein content and highly digestible fiber, and secondarily for beef cattle, horses, sheep, and goats.²⁶²⁷ Alfalfa hay is a widely used protein and fiber source for meat rabbits. In poultry diets, dehydrated alfalfa and alfalfa leaf concentrates are used for pigmenting eggs and meat, because of their high content in carotenoids, which are efficient for colouring egg yolk and body lipids.²⁸ Humans also eat alfalfa sprouts in salads and sandwiches.²⁹³⁰ Dehydrated alfalfa leaf is commercially available as a dietary supplement in several forms, such as tablets, powders and tea.³¹ Fresh alfalfa can cause bloating in livestock, so care must be taken with livestock grazing on alfalfa because of this hazard.³²

Like other legumes, its root nodules contain bacteria, Sinorhizobium meliloti, with the ability to fix nitrogen, producing a high-protein feed regardless of available nitrogen in the soil.³³ Its nitrogen-fixing ability (which increases soil nitrogen) and its use as an animal feed greatly improve agricultural efficiency.³⁴³⁵

Alfalfa can be sown in spring or fall, and does best on well-drained soils with a neutral pH of 6.8–7.5.³⁶³⁷ Alfalfa requires sustained levels of potassium and phosphorus to grow well.³⁸ It is moderately sensitive to salt levels in both the soil and irrigation water, although it continues to be grown in the arid southwestern United States, where salinity is an emerging issue.³⁹⁴⁰⁴¹ Soils low in fertility should be fertilized with manure or a chemical fertilizer, but correction of pH is particularly important.⁴² Usually a seeding rate of 13–20 kg/ha (12–18 lb/acre) is recommended, with differences based upon region, soil type, and seeding method.⁴³ A nurse crop is sometimes used, particularly for spring plantings, to reduce weed problems and soil erosion, but can lead to competition for light, water, and nutrients.⁴⁴

In most climates, alfalfa is cut three to four times a year, but it can be harvested up to 12 times per year in Arizona and southern California.⁴⁵⁴⁶ Total yields are typically around 8 tonnes per hectare (3+1⁄2 short tons per acre) in temperate environments, but yields have been recorded up to 20 tonnes per hectare (9 short tons per acre).⁴⁷ Yields vary with region, weather, and the crop's stage of maturity when cut. Later cuttings improve yield, but with reduced nutritional content.⁴⁸

History

Alfalfa seems to have originated in south-central Asia, and was first cultivated in Central Asia.⁴⁹⁵⁰ 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 given to cattle, but new provender is at first to be administered very sparingly, because it bloats up the cattle."⁵¹

The medieval Arabic agricultural writer Ibn al-'Awwam, who lived in Spain in the later 12th century, discussed how to cultivate alfalfa, which he called الفصفصة (al-fiṣfiṣa).⁵² A 13th-century general-purpose Arabic dictionary, Lisān al-'Arab, says that alfalfa is cultivated as an animal feed and consumed in both fresh and dried forms.⁵³ It is from the Arabic that the Spanish name alfalfa was derived.⁵⁴

In the 16th century, Spanish colonizers introduced alfalfa to the Americas as fodder for their horses.⁵⁵

In the North American colonies of the eastern US in the 18th century, it was called "lucerne", and many trials at growing it were made, but generally without sufficiently successful results.⁵⁶ Relatively little is grown in the southeastern US today.⁵⁷ Lucerne (or luzerne) is the name for alfalfa in Britain, Australia, France, Germany, and a number of other countries. Alfalfa seeds were imported to California from Chile in the 1850s. That was the beginning of a rapid and extensive introduction of the crop over the western US⁵⁸ and introduced the word "alfalfa" to the English language. Since North and South America now produce a large part of the world's output, the word "alfalfa" has been slowly entering other languages.

Harvesting

When alfalfa is to be used as hay, it is usually cut and baled.⁵⁹ Loose haystacks are still used in some areas, but bales are easier for use in transportation, storage, and feed.⁶⁰ 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.⁶¹ When using farm equipment rather than hand-harvesting, a swather cuts the alfalfa and arranges it in windrows.⁶² In areas where the alfalfa does not immediately dry out on its own, a machine known as a mower-conditioner is used to cut the hay.⁶³ The mower-conditioner has a set of rollers or flails that crimp and break the stems as they pass through the mower, making the alfalfa dry faster.⁶⁴ 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. Other bale sizes are three-string, and so on up to half-ton (six-string) "square" bales – actually rectangular, and typically about 40 cm × 45 cm × 100 cm (16 in × 18 in × 39 in).⁶⁵ Small square bales weigh from 25 to 30 kg (55 to 66 lb) depending on moisture, and can be easily hand separated into "flakes". Cattle ranches use large round bales, typically 1.4 to 1.8 m (4+1⁄2 to 6 ft) in diameter and weighing from 500 to 1,000 kg (1,100 to 2,200 lb). These bales can be placed in stable stacks or in large feeders for herds of horses or unrolled on the ground for large herds of cattle.⁶⁶ The bales can be loaded and stacked with a tractor using a spike, known as a bale spear that pierces the center of the bale,⁶⁷ or they can be handled with a grapple (claw) on the tractor's front-end loader.

When used as feed for dairy cattle, alfalfa is often made into haylage by a process known as ensiling.⁶⁸ Rather than being dried to make dry hay, the alfalfa is chopped finely and fermented in silos, trenches, or bags, where the oxygen supply can be limited to promote fermentation.⁶⁹ The anaerobic fermentation of alfalfa allows it to retain high nutrient levels similar to those of fresh forage, and is also more palatable to dairy cattle than dry hay.⁷⁰ In many cases, alfalfa silage is inoculated with different strains of microorganisms to improve the fermentation quality and aerobic stability of the silage.⁷¹⁷²

Production

During the early 2000s, alfalfa was the most cultivated forage legume in the world.⁷³ Worldwide production was around 436 million tons in 2006.⁷⁴ In 2009, alfalfa was grown on approximately 30 million hectares (74 million acres) worldwide; of this North America produced 41% (11.9 million hectares; 29 million acres), Europe produced 25% (7.12 million hectares; 17.6 million acres), South America produced 23% (7 million hectares; 17 million acres), Asia produced 8% (2.23 million hectares; 5.5 million acres), and Africa and Oceania produced the remainder.⁷⁵ The US was the largest alfalfa producer in the world by area in 2009, with 9 million hectares (22 million acres), but considerable production area is found in Argentina (6.9 million hectares; 17 million acres), Canada (2 million hectares; 4.9 million acres), Russia (1.8 million hectares; 4.4 million acres), Italy (1.3 million hectares; 3.2 million acres), and China (1.3 million hectares; 3.2 million acres).⁷⁶

United States

In the United States in 2012, the leading alfalfa-growing states were California, Idaho, and Montana.⁷⁷ Alfalfa is predominantly grown in the northern and western US;⁷⁸ it can be grown in the southeastern US, but leaf and root diseases, poor soils, and a lack of well-adapted varieties are often limitations.⁷⁹

In California, varieties resistant to the spotted alfalfa aphid (Therioaphis maculata) are necessary, but even that is not always enough due to constant resistance evolution.⁸⁰

Australia

Lucerne grown in Australia prior to the 1970s was from seed brought from Great Britain in the early years of colonization, with production most successful in the Hunter and Peel river valleys. Hunter River cv. was the first lucerne variety developed for the Australian environment and was bred from selections of pre-existing lucerne stands in the Upper Hunter River (New South Wales) region.⁸¹ Pest burdens from the spotted alfalfa aphid in the 1970s caused significant destruction of NSW lucerne paddocks, with surviving populations being used as parents for Hunterfield cv. (released 1983). This variety showed significant improvement of resistance to spotted alfalfa aphid.⁸²

Grazing is the most commonly used form of pasture management in Australia, with many varieties of lucerne specifically being bred for low rainfall, high grazing pressure.

New South Wales produces 40% of Australia's lucerne.⁸³ Due to the introduction of the spotted alfalfa aphid (Therioaphis maculata) in 1977 ⁸⁴ all varieties grown there must be resistant to it.⁸⁵⁸⁶⁸⁷ South Australia is home to 83% of all lucerne seed production in Australia.⁸⁸ Much of this seed industry is centred around the town of Keith, South Australia, also encompassing the neighbouring localities of Tintinara, Bordertown, Willalooka, Padthaway and Naracoorte.

Alfalfa and bees

Alfalfa seed production requires the presence of pollinators when the fields of alfalfa are in bloom.⁸⁹ Alfalfa pollination is somewhat problematic, however, because western honey bees, the most commonly used pollinator, are less than ideal for this purpose; the pollen-carrying keel of the alfalfa flower trips and strikes pollinating bees on the head, which helps transfer the pollen to the foraging bee.⁹⁰ Western honey bees, however, do not like being struck in the head repeatedly and learn to defeat this action by drawing nectar from the side of the flower. The bees thus collect the nectar, but carry no pollen, so do not pollinate the next flower they visit.⁹¹ Because older, experienced bees do not pollinate alfalfa well, most pollination is accomplished by young bees that have not yet learned the trick of robbing the flower without tripping the head-knocking keel.

When western honey bees are used to pollinate alfalfa, the beekeeper stocks the field at a very high rate to maximize the number of young bees.⁹² However, Western honey bee colonies may suffer protein stress when working alfalfa only, because alfalfa pollen protein is deficient in isoleucine, one of the amino acids essential in the diet of honeybee larvae.

Today, the alfalfa leafcutter bee (Megachile rotundata) is increasingly used to circumvent these problems.⁹³ As a solitary but gregarious bee species, it does not build colonies or store honey, but is a very efficient pollinator of alfalfa flowers.⁹⁴ Nesting is in individual tunnels in wooden or plastic material, supplied by the alfalfa seed growers.⁹⁵ The leafcutter bees are used in the Pacific Northwest, while western honeybees dominate in California alfalfa seed production.⁹⁶

M. rotundata was unintentionally introduced into the US during the 1940s, and its management as a pollinator of alfalfa has led to a three-fold increase in seed production in the U.S. The synchronous emergence of the adult bees of this species during alfalfa blooming period in combination with such behaviors as gregarious nesting, and utilization of leaves and nesting materials that have been mass-produced by humans provide positive benefits for the use of these bees in pollinating alfalfa.⁹⁷

A smaller amount of alfalfa produced for seed is pollinated by the alkali bee, mostly in the northwestern US. It is cultured in special beds near the fields. These bees also have their own problems. They are not portable like honey bees, and when fields are planted in new areas, the bees take several seasons to build up.⁹⁸ Honey bees are still trucked to many of the fields at bloom time.

The rusty patched bumble bee, Bombus affinis, is important to the agricultural industry as well as for the pollination of alfalfa.⁹⁹ It is known that members of this species pollinate up to 65 different species of plants, and it is the primary pollinator of key dietary crops, such as cranberries, plums, apples, onions, and alfalfa.¹⁰⁰

Varieties

Considerable research and development has been done with this important plant. Older cultivars such as 'Vernal' have been the standard for years, but many public and private varieties better adapted to particular climates are available.¹⁰¹ Private companies release many new varieties each year in the US.¹⁰²

Most varieties go dormant in the fall, with reduced growth in response to low temperatures and shorter days.¹⁰³ 'Nondormant' varieties that grow through the winter are planted in long-season environments such as Mexico, Arizona, and Southern California, whereas 'dormant' varieties are planted in the Upper Midwest, Canada, and the Northeast.¹⁰⁴ 'Nondormant' varieties can be higher-yielding, but they are susceptible to winter-kill in cold climates and have poorer persistence.¹⁰⁵

Most alfalfa cultivars contain genetic material from sickle medick (M. falcata), a crop wild relative of alfalfa that naturally hybridizes with M. sativa to produce sand lucerne (M. sativa ssp. varia). This species may bear either the purple flowers of alfalfa or the yellow of sickle medick, and is so called for its ready growth in sandy soil.¹⁰⁶ Traits for insect resistance have also been introduced from M. glomerata and M. prostrata, members of alfalfa's secondary gene pool.¹⁰⁷

Most of the improvements in alfalfa over the last decades have consisted of better disease resistance on poorly drained soils in wet years, better ability to overwinter in cold climates, and the production of more leaves. Multileaf alfalfa varieties have more than three leaflets per leaf.¹⁰⁸

Alfalfa growers or lucerne growers have a suite of varieties or cultivars to choose from in the seed marketplace and base their selection on a number of factors including the dormancy or activity rating, crown height, fit for purpose (i.e., hay production or grazing), disease resistance, insect pest resistance, forage yield, fine leafed varieties and a combination of many favourable attributes. Plant breeding efforts use scientific methodology and technology to strive for new improved varieties.

The L. Teweles Seed Company claimed it created the world's first hybrid alfalfa.¹⁰⁹

Wisconsin and California and many other states publish alfalfa variety trial data. A complete listing of state variety testing data is provided by the North American Alfalfa Improvement Conference (NAAIC) State Listing, as well as additional detailed alfalfa genetic and variety data published by NAAIC.

Genetic modification

Roundup Ready alfalfa (RRA), a genetically modified variety, was released by Forage Genetics International in 2005. This was developed through the insertion of a gene owned by Monsanto Company that confers resistance to glyphosate, a broad-spectrum herbicide, also known as Roundup. Although most grassy and broadleaf plants, including ordinary alfalfa, are killed by Roundup, growers can spray fields of Roundup Ready alfalfa with the glyphosate herbicide and kill the weeds without harming the alfalfa crop.

Legal issues in the US

In 2005, after completing a 28-page environmental assessment¹¹⁰ the United States Department of Agriculture (USDA) granted RRA nonregulated status¹¹¹ under Code of Federal Regulations Title 7 Part 340,¹¹² which regulates, among other things, the introduction (importation, interstate movement, or release into the environment) of organisms and products altered or produced through genetic engineering that are plant pests or that there is reason to believe are plant pests. Monsanto had to seek deregulation to conduct field trials of RRA, because the RRA contains a promoter sequence derived from the plant pathogen figwort mosaic virus.¹¹³ The USDA granted the application for deregulation, stating that the RRA with its modifications: "(1) Exhibit no plant pathogenic properties; (2) are no more likely to become weedy than the nontransgenic parental line or other cultivated alfalfa; (3) are unlikely to increase the weediness potential of any other cultivated or wild species with which it can interbreed; (4) will not cause damage to raw or processed agricultural commodities; (5) will not harm threatened or endangered species or organisms that are beneficial to agriculture; and (6) should not reduce the ability to control pests and weeds in alfalfa or other crops."¹¹⁴ Monsanto started selling RRA and within two years, more than 300,000 acres were devoted to the plant in the US.¹¹⁵

The granting of deregulation was opposed by many groups, including growers of non-GM alfalfa who were concerned about gene flow into their crops.¹¹⁶ In 2006, the Center for Food Safety, a US non-governmental organization that is a critic of biotech crops, and others, challenged this deregulation in the United States District Court for the Northern District of California.¹¹⁷ Organic growers were concerned that the GM alfalfa could cross-pollinate with their organic alfalfa, making their crops unsalable in countries that ban the growing of GM crops.¹¹⁸ The District Court ruled that the USDA's environmental assessment did not address two issues concerning RRA's effect on the environment,¹¹⁹ and in 2007, required the USDA to complete a much more extensive environmental impact statement (EIS). Until the EIS was completed, they banned further planting of RRA but allowed land already planted to continue.¹²⁰¹²¹ The USDA proposed a partial deregulation of RRA but this was also rejected by the District Court.¹²² Planting of RRA was halted.

In June 2009, a divided three-judge panel on the 9th U.S. Circuit Court of Appeals upheld the District Court's decision.¹²³ Monsanto and others appealed to the US Supreme Court.¹²⁴

On 21 June 2010, in Monsanto Co. v. Geertson Seed Farms, the Supreme Court overturned the District Court decision to ban planting RRA nationwide as there was no evidence of irreparable injury.¹²⁵ They ruled that the USDA could partially deregulate RRA before an EIS was completed. The Supreme Court did not consider the District Court's ruling disallowing RRA's deregulation and consequently RRA was still a regulated crop waiting for USDA's completion of an EIS.¹²⁶

This decision was welcomed by the American Farm Bureau Federation, Biotechnology Industry Organization, American Seed Trade Association, American Soybean Association, National Alfalfa and Forage Alliance, National Association of Wheat Growers, National Cotton Council, and National Potato Council.¹²⁷ In July 2010, 75 members of Congress from both political parties sent a letter to Agriculture Secretary Tom Vilsack asking him to immediately allow limited planting of genetically engineered alfalfa.¹²⁸¹²⁹ However the USDA did not issue interim deregulatory measures, instead focusing on completing the EIS. Their 2,300-page EIS, published in December 2010, concluded that RRA would not affect the environment.¹³⁰

Three of the biggest natural food brands in the US lobbied for a partial deregulation of RRA,¹³¹ but in January 2011, despite protests from organic groups, Secretary Vilsack announced that the USDA had approved the unrestricted planting of genetically modified alfalfa and planting resumed.^132133134 Secretary Vilsack commented, "After conducting a thorough and transparent examination of alfalfa ... APHIS [Animal and Plant Health Inspection Service] has determined that [RRA] is as safe as traditionally bred alfalfa."¹³⁵ About 20 million acres (8.1 million hectares) of alfalfa were grown in the US, the fourth-biggest crop by acreage, of which about 1% were organic. Some biotechnology officials forecast that half of the US alfalfa acreage could eventually be planted with GM alfalfa.¹³⁶

The National Corn Growers Association,¹³⁷ the American Farm Bureau Federation,¹³⁸ and the Council for Biotech Information¹³⁹ warmly applauded this decision. Christine Bushway, CEO of the Organic Trade Association, said, "A lot of people are shell-shocked. While we feel Secretary Vilsack worked on this issue, which is progress, this decision puts our organic farmers at risk."¹⁴⁰ The Organic Trade Association issued a press release in 2011 saying that the USDA recognized the impact that cross-contamination could have on organic alfalfa and urged them to place restrictions to minimize any such contamination.¹⁴¹ However, organic farming groups, organic food outlets, and activists responded by publishing an open letter saying that planting the "alfalfa without any restrictions flies in the face of the interests of conventional and organic farmers, preservation of the environment, and consumer choice".¹⁴² In addition to House Agriculture Committee Chairman Frank Lucas, Senator Debbie Stabenow (Chairwoman of the Senate Agriculture Committee) and Senator Richard Lugar strongly supported the decision, respectively stating that it would give growers "the green light to begin planting an abundant, affordable and safe crop"¹⁴³ and give farmers and consumers the "choice ... in planting or purchasing food grown with GM technology, conventionally, or organically".¹⁴⁴ In a joint statement, US Senator Patrick Leahy and Representative Peter DeFazio said the USDA had the "opportunity to address the concerns of all farmers", but instead "surrender[ed] to business as usual for the biotech industry".¹⁴⁵

In March 2011, the non-profit Center for Food Safety appealed the deregulation decision,¹⁴⁶ which the District Court for Northern California rejected in 2012.¹⁴⁷

Safety concerns

Alfalfa sprouts may contain microbiological pathogens, mainly from Salmonella or E. coli, which have caused numerous food product recalls and illness outbreaks, putting sprouts into a "high risk" category for food safety.^148149150 People with weakened immune systems, such as the elderly, pregnant women, or those taking prescription drugs affecting the immune system, should not eat sprouts.¹⁵¹

With long-term human consumption of alfalfa seeds, several safety concerns and medication interactions may result, including possible reactions similar to lupus erythematosus, an autoimmune disease.¹⁵²

Other concerns are for women during pregnancy or breast-feeding, hormone-sensitive conditions (such as breast, uterine, and ovarian cancers), and for people with diabetes.¹⁵³ Alfalfa may interact with warfarin (e.g. Coumadin), birth control pills (contraceptive drugs), and estrogens.¹⁵⁴

Toxicity of canavanine

Raw alfalfa seeds and sprouts are a source of the amino acid canavanine. Much of the canavanine is converted into other amino acids during germination, so sprouts contain much less canavanine than unsprouted seeds.¹⁵⁵ Canavanine competes with arginine, resulting in the synthesis of dysfunctional proteins. Raw unsprouted alfalfa has toxic effects in primates, including humans, which can result in lupus-like symptoms and other immunological diseases in susceptible individuals.¹⁵⁶¹⁵⁷ Stopping consumption of alfalfa seeds can reverse the effects.¹⁵⁸

Phytoestrogens and effect on livestock fertility

Alfalfa, like other leguminous crops, is a source of phytoestrogens,¹⁵⁹ including spinasterol,¹⁶⁰ coumestrol, and coumestan.¹⁶¹ Because of this, grazing on alfalfa during breeding can cause reduced fertility in sheep and in dairy cattle if not effectively managed.¹⁶²¹⁶³

Coumestrol levels in alfalfa have been shown to be elevated by fungal infection, but not significantly under drought stress¹⁶⁴ or aphid infestation.¹⁶⁵ Grazing management can be utilised to mitigate the effects of coumestrol on ewe reproductive performance, with full recovery after removal from alfalfa.¹⁶⁶ Coumestrol levels in unirrigated crops can be predicted practically using weather variables.¹⁶⁷

Nutrition

Raw alfalfa seed sprouts are 93% water, 2% carbohydrates, 4% protein, and contain negligible fat. In a 100-gram (3+1⁄2-ounce) reference amount, raw alfalfa sprouts supply 96 kilojoules (23 kilocalories) of food energy and 29% of the Daily Value of vitamin K. They are a moderate source of vitamin C, some B vitamins, phosphorus, and zinc.

Sprouts

Sprouting alfalfa seeds is the process of germinating seeds at the immature stage for use as a garnish on various food preparations, such as salads. Although sprouts may be grown in soil, they are more commonly germinated in a soilless medium using drums, trays or racks.¹⁶⁸
