The Benefits of Growing Lucerne Alfalfa to Dairy Cows

  • Clicks:

Lucerne is a popular crop across the continent but remains an almost untapped protein resource in the UK. However, it has huge potential in dairy diets to help displace imported soya and help UK farmers become self-sufficient in homegrown protein.

Rhian Price speaks to a grower and a dairy farmer seeing good results from feeding the legume.

Grower Case Study: Simon Gittins, Wykey Farm, Shropshire

Arable farmer Simon Gittins started growing lucerne four years ago and is so impressed with the crop he hopes to double the amount grown to 81ha (200 acres) in the next couple of years.

Mr Gittins grows 1,275ha (3,150 acres) of eight different crops and reckons lucerne has the potential to be the most profitable of all.

“Lucerne is bang on message in modern UK agriculture,” he says. ”It’s a legume so there is no need for sprays or nitrogen fertiliser. You are basically going zero-till for four years.”

Farm Facts: Wykey Farm, Shropshire

Farming 1,275ha (3,150 acres), half owned with the balance contract-farmed or on various rental agreements

Growing wheat, rape, maize, sugar beet, hybrid rye, lucerne, grass, forage rye and turnips.

He has a 1.9MW anaerobic digester and is installing a second ground-source heat system this year to take the farm’s total renewable drying floor capacity up to 5.6MW.

This is used to dry all of the farm’s cereals and OSR as well as grass and lucerne to produce high-protein, highly digestible hay. This is baled and sold locally.

“I think we will see a move towards providing more homegrown protein to displace high-food-mile soya from South America,” he says.

Establishment

Mr Gittins grows the varieties Timbale and Galaxy. Seed is planted into free-draining soils in late spring, following crops of hybrid rye, forage rye or grass.

“Establishment is critical with lucerne. We create a stale seed-bed and then drill conventionally, ensuring the field is firm and level.”

He says it is a low-cost crop to grow. Establishment and variable costs equate to £247/ha (£100/acre). Harvesting and baling takes it up to about £618/ha (£250/acre).

Solid digestate is applied at a rate of 25t/ha, primarily for potash, before sowing, or to already-established crops before first cut in the spring. This provides all the potash the plant requires for that season, with little else applied because the crop fixes its own nitrogen.

Harvest

Four cuts are taken annually, with a fully established crop typically yielding 11t DM/ha (4.5t/acre) at 20-25% protein.

Much of the protein (70%) is found in the leaf of the plant. This poses a problem for field-dried lucerne hay as the leaf can shatter and be left in the field.

To avoid this, Mr Gittins has fine-tuned his approach to harvesting. He mows it and picks it up within 24 hours using a forage box with the knives removed.

“This ensures the leaf is retained and enables us to achieve protein analyses of 20-25%,” he says. “This is appreciably higher than most other lucerne hay on the market.”

Lucerne is taken to the drying sheds where it is spread evenly over the drying floors and stays for four to seven days until it reaches 85-90% DM.

Mr Gittins has converted former potato stores into drying sheds. Ground-source and waste heat from the AD plant are used to dry the lucerne. He uses a Welvent system which draws ambient air through heat exchangers and then forces the warmed air underneath wooden slatted drying floors, on top of which sits the crop.

The crop is baled straight from the drying floor using a Claas 3200 baler. Mr Gittins has imported a HayXit19 from Switzerland to allow stationary baling. It is the first of its kind in the world and cost about £40,000.

Before he set up the static baler, a diet feeder was used to dispense the hay in a swath on the concrete. The tractor and baler would then drive up and down picking up the lucerne.

It was a laborious process, baling only 3-4t/hr. The HayXit19 can bale six times as much – 25t/hr.

The 500kg quadrant bales are sold to dairy farmers for £200-240/t, depending on distance. They are delivered in 20t loads on lorries with curtain sides to prevent leaf being lost in transport.

This autumn the first 20ha Mr Gittins sowed four years ago will return to standing cropping. He is keen to see what impact this will have on soil fertility.

“We will be sowing wheat after lucerne this autumn. We are hoping to see a reduction in variable costs from reduced fertiliser and spray requirements, and a possible increase in yield due to improved soil health and structure.”

Advice on growing lucerne

Site Must be established into free-draining soil with a pH of 6.2-6.4 and soil indices of at least 2 for potash and phosphate.

Selecting a variety Choose a dormancy rating of 4-5 and a variety with a thin stem to promote synergistic wilting speed with the leaf.

Fertiliser Requires 8kg of phosphate and 30kg of potash per tonne grown. It fixes its own nitrogen, so it requires fertiliser only where it follows a nitrogen-hungry crop such as wheat.

Cost £1,100-1,200/ha to establish (includes seed and machinery costs). Input requirements are very low and would suit organic farms.

Establishment Requires a tight, finely compacted seed-bed. Three options for sowing: Drill it; broadcast the seed and run over it with power harrow, then roll it; or sow with a nurse crop such as spring barley (at 50-75% rate) to help it outcompete weeds. When the barley is 7.5-10cm, lucerne should be drilled and spring barley can be whole-cropped.

Seed depth No deeper than 1cm as the seed is small and won’t emerge if deeper.

Timing Sow from 15 April onwards into warm soil.

Harvest Cut the crop no lower than 7-10cm from the base. The base is high in lignin, which can’t be digested by the cow. Wilt for 24-36hours, weather dependent. Can be baled or clamped.

Additive Crop is high in protein, so an additive is recommended to rapidly bring down pH.

Persistency 4-6 years.

Expected yield 12-14t DM/ha at 18-25% protein.
