Protein crops to surge says Barenbrug



Written by John Swire

Enquiries about red clover have been so strong that the company has released an updated set of guidelines to help growers sow and manage its red clover varieties most effectively.

“Soya has been trading at well over £400/t this year,” points out Mhairi Dawson, Barenbrug UK’s research and development manager.

“That’s prompted people to give more consideration to how they source their essential protein ration,” explains Ms Dawson, who is also the company’s regional manager for Scotland.

But the thinking is about more than economics, says Ms Dawson.

“Farmers are increasingly aware that we’ve a collective responsibility to reduce our carbon ‘spending’. The NFU’s pledge to deliver Net Zero by 2040 has sharpened a lot of minds.

“In talking to farmers, it’s clear that they are making more conscious decisions to reduce food miles – high, in the case of imported soya – and trying to cut back on carbon-intensive inputs such as nitrogen fertiliser.”

When it comes to nitrogen, red clover’s ability to fix more than 200kg per hectare per year is one of the factors driving its popularity. The Post-Brexit policy focus on agri-environmental issues has prompted speculation that the NVZ areas could expand, or that there will be an altogether stricter approach to nitrogen applications.

“Red clover presents an opportunity to reduce artificial nitrogen, yet maintain a high-quality forage,” Ms Dawson says.

“Defra’s recent urea fertiliser consultation has increased expectations that things will change, eventually, and I think that’s encouraged farmers to consider how they might adapt their operations, to adopt a more sustainable approach,” she adds.

Red clover’s palatability and favourable CP of 18-20 per cent makes it a good legume choice in pure grass swards, promoting increased intakes that can boost both milk yield and daily liveweight gain. And as a deep-rooted flowering species, it also has the potential to be beneficial for soil structure, building organic matter and providing a food source for pollinators.

“Red clover has the potential to be a very valuable crop for UK livestock farmers,” says Ms Dawson, “but careful management is required, to maintain its population in the sward.”

Research conducted last year amongst 200 farmers in the Netherlands, where red clover has become well-established, revealed quality, high protein yields, biodiversity and nitrogen reduction were the main factors driving adoption of the legume, and 73 per cent said they planned to continue their use of red clover as an important source of quality livestock feed.

“We also looked at the most successful farmers, those having consistent success growing red clover, to identify which management practices delivered the best results,” explains Ms Dawson. “It’s this research that has informed our new red clover management guidelines.”

Barenbrug UK– guidelines for red clover success

  • Sow in summer, not in spring.
  • Drilling rate should be a minimum of 5kg/ha.
  • Do not cut clover below Manage the growing crown very carefully.
  • Allow the crop to reach at least 3500kg DM/habefore cutting. Do not rely on any percentage of flowering figure.
  • Use no more than 100kg N/ha/annum.
  • Red clover benefits from high P & K levels, so there are no restrictions on organic manure applications.

Rejuvenating swards: Which option is best?

Maintaining grass quality during mid-season grazing is important. Farmers can maintain quality by entering ideal grazing covers of 1,300 – 1,500kg DM/ha, and grazing down to a residual of 4cm every rotation.

If you are now in a situation where cows are not cleaning out paddocks as well as they should be, leading to the development of steamy grass within the sward, here are some options.

Common options for rejuvenating swards include:

  1. Take a silage cut, probably into bales, remove the material and start again with the aftermath...
