Why every Welsh farm should set a goal to increase soil organic carbon

Published

on

REDUCING soil disturbance, growing cover crops and increasing plant diversity will help Welsh farms better cope with future climate challenges.

As the industry moves towards utilising more sustainable food production techniques, the goal of every farm should be to increase soil organic carbon, insists Neil Fuller, an expert in the science of soil management.

At a recent Farming Connect soil health event at Treathro Farm, a beef farm near Strumble Head, Pembrokeshire, where David and Debbie Best are trialling different soil management practices, Mr Fuller said soil health offered significant sustainability and productivity outcomes for farm businesses.

As a starting point, he recommended getting an active measurement of the health of farm soils – its biological, physical and chemical health.

From microscopic fungi and bacteria to earthworms and beetles, soil contains billions of organisms.

“Most are beneficial to crops and perform a variety of functions, from breaking down organic matter and improving soil structure and drainage,’’ said Mr Fuller.

Many will also act as predators for pests, reducing the need for chemicals.

Earthworms are good indicators of soil health as they are sensitive to pH, waterlogging, compaction, rotations, tillage and organic matter.

Their numbers and distribution across a field can reveal what is going on under the surface.

Mr Fuller brought this message to life with a ‘soil safari’ by examining different soils and worm activity under a high-powered microscope and shared on a big screen.

Farm soils should have three types of earthworms – surface, topsoil and deep-burrowing earthworms.

Small surface worms live and feed on surface litter and organic amendments, topsoil earthworms are found in the topsoil, forming horizontal burrows that mix the soil and mobilise nutrients, and deep-burrowing earthworms make deep, vertical burrows.

While most soils have topsoil worms, the absence of surface and deep-burrowing worms suggest that the soil has been overworked and soil functioning is compromised.

Mr Fuller said the physical structure of the soil also needs to be considered.

If soil is compacted, there is less room for plant roots to grow and for air and water to circulate.

Compacted soils have lower infiltration and drainage rates, as well as reduced biological activity, plant root growth and yields.

They are also less able to cope with weather extremes, warned Mr Fuller.

Chemical properties are also important to soil health. Maintaining the optimum pH level and adequate supply of plant nutrients helps to support crop growth.

At Treathro, the Bests are working with Farming Connect to examine the impact of different management techniques and sward types on soil microbiology.

There are four trial fields: in one the Bests are rotational grazing their Red Devon suckler herd on permanent pasture and in another they intend to grow a minimum tillage herbal ley.

The other two trial sites are a field of perennial ryegrass and white clover used for haylage and a cliff-top field that is an SSSI and only lightly grazed by ponies.

Non Williams, Farming Connect Carbon Specialist Officer, said the average soil carbon stock in the top 10cm of soil was founds to be highest in the cliff top field, at 62.2 tonnes a hectare (t/ha), while in the rotationally grazed permanent pasture it was 51t/hectare (ha).

In the field used for haylage, it was 45.7t/ha and 41.7t/ha in remaining field.

Dr Williams said that at greater soil depth, 30-50cm below ground, the average soil carbon stock was highest – 30.4t/ha – in the perennial ryegrass and clover field used for haylage.

The project is also examining the levels of beneficial bacteria, fungi, protozoa and nematodes in the soil at Treathro.

Lynfa Davies, Farming Connect Biodiversity Specialist Officer, said this had shown that there were very dominant levels of beneficial bacteria.

Ideally fungi levels should be higher but she suggested low levels were typical of many agricultural soils.

“This can be improved through regenerative practices such as using deep-rooted leys using min-till methods which allow fungi to proliferate,’’ said Ms Davies.

Using less artificial fertilisers and increasing soil carbon will also help, she added.

But she warned that improving soil health is not a rapid process.

“It is important to remember that building soil health takes time and it may take several years before significant changes are seen,’’ said Ms Davies.

Benefits of breeding for wool quality explained as global demand rises

Published

on

AS GLOBAL demand for sustainable textiles continues to grow, wool is presenting farmers with a renewed opportunity to increase revenue by improving flock quality.

Competition shearer and sheep farmer Matt Smith has been working for several years to enhance the value of wool from his Romney flock. However, he believes it could take another decade before he achieves the level of fleece quality needed to deliver a significant uplift in returns.

Sheep farmer: Matt Smith

“We have invested heavily in genetics, particularly to improve micron density within the flock,” he said. “High-quality wool is in demand for premium, sustainable clothing, and better micron density combined with a higher comfort factor will always attract stronger prices.”

While his flock already produces wool that commands a good return, Smith believes there is further potential—particularly with the introduction of new technology that allows more precise measurement of wool quality.

“I have been fortunate to trial a new handheld device from Woven Optics, which measures micron and comfort factor in real time,” he explained. “It has allowed me to clearly see how breeding decisions are influencing wool quality.”

Developed in Australia, the Woven Optics device is designed for use in a range of conditions and has proven to be an accurate on-farm testing tool. In the UK, the company has partnered with Heiniger to bring the technology to farmers.

“I have been working with Hefin Rowlands from Heiniger to monitor our Romneys using the device,” Smith added. “While it represents a significant investment, it is small compared to what we already spend on genetics.”

He believes the technology offers farmers a practical way to track improvements and better understand how breeding choices impact wool value.

“It is an enabler,” he said. “Having the ability to test wool on farm in seconds could help shift the industry back towards prioritising wool as a key genetic trait.”

Smith argues that this shift is not just about profitability, but also about animal health and long-term sustainability.

“In recent years, breeding has focused heavily on carcass weight to meet market demand for larger cuts of meat, and wool quality has been overlooked,” he said. “That has had unintended consequences.”

Drawing on his experience as a contract shearer across the UK, Smith has observed a decline in fleece quality in many flocks.

“I am seeing more yellowing in fleeces and a stronger odour, which can increase susceptibility to fly problems,” he said.

He warns that neglecting wool quality may also be contributing to a growing reliance on chemicals, antibiotics and anthelmintics—raising concerns about resistance and animal welfare.

“As a sheep breeding nation, we risk forgetting how important wool quality is to overall sheep health,” he added. “Changes in fleece condition, combined with warmer temperatures, can increase flystrike risk. By breeding for better wool, we can reduce these issues and cut reliance on pharmaceuticals.”

Smith believes that embracing technology such as the Woven Optics device could help reverse current trends.

“Breeding in the wrong direction is not sustainable,” he said. “By improving wool quality, farmers can produce healthier, more valuable sheep. The tools are now available, and the opportunity is there to restore wool as a priority within UK sheep farming.”

205-unit storage site at Pembrokeshire farm submitted to planners

Published

on

A CALL to allow a Pembrokeshire farm to keep a storage facility for more than 200 caravans, boats, cars and farm machines as a form of diversification has been submitted to county planners.

In an application to Pembrokeshire County Council, Mr & Mrs Davies, through agent A.D Architectural Design Consultants Ltd, seek retrospective permission for a farm diversification scheme to accommodate the storage of caravans, boats, cars and farm machinery in four of eight agricultural sheds and on hard-standing concrete courtyards at Froghall Farm, Spittal.

The works were completed back in 2019.

A supporting statement accompanying the application said: “At present, four of the eight shed structures on the site form part of the caravan and boat storage scheme, with additional touring caravans stored externally on the concrete courtyards.”

It said the storage provision was split as follows: Shed 1 – farm workshop, and 30 caravans, motorhomes, boats & cars; shed 2 – 16 caravans; shed 3 – 28 caravans, motorhomes, boats & cars – 28; shed 8 – cubicle shed, 11 units of farm machines, motorhomes & caravans; courtyard storage of 120 touring caravans, for an overall storage of 205 units.

The statement added: “It would take place in an accessible location, would incorporate sustainable transport and accessibility principles and would not result in a detrimental impact on highway safety or in traffic exceeding the capacity of the highway network; access road is a no-through road with no increase in traffic due to the nature of development.

“There won’t be a constant stream/flow of traffic as the site’s used for storage. Our client offers a towing service to sites in and around Pembrokeshire, which is used by 45 per cent of their customers, who are unable or prefer not to tow themselves. This gives our client control over the flow of traffic.”

The application will be considered by county planners at a later date.

Plans to rebuild arson hit building at farm with one of largest sheep flocks in Wales

Published

on

A CALL to rebuild a fire-damaged Pembrokeshire farm building, as a family home to help manage one of the largest sheep flocks in Wales, has been submitted to the national park.

In the application to Pembrokeshire Coast National Park, D B Davies and Sons through agent Harries Planning Design Management, with a supporting statement by Reading Agricultural Consultants Ltd, seek permission to renovate an existing fire-damaged dwelling, together with the conversion and extension of outbuildings to form an agricultural worker’s dwelling at Mynydd Du, Rosebush.

The supporting statement through Reading Agricultural Consultants Ltd says Mynydd Du is part of a wider holding which includes Eisteddfa Fawr and land around the village of Brynberian, the farms approximately six km apart, with land under control of the applicant amounting to some 1,500 acres, with a further 3,000 acres of Preseli mountain common land also used; the land accommodating a 5,000-ewe flock with 10 suckler cows and followers.

It says DB Davies & Sons Unlimited, has five partners: the two Davies brothers, Berian and Ken; their wives; and Berian’s son, Dyfed.

Berian and Ken are in their late 70s, with most of the heavy work on the farm is undertaken by Dyfed.

Dyfed and his wife Megan are first language Welsh speakers, living some 10 km away in Nevern, while Berian and Ken, and their wives, live at Eisteddfa Fawr, Brynberian.

The dwelling at Mynydd Du, where most sheep are now wintered, is structurally sound and repairable but has been unoccupied since 1990, and was subject to arson circa 2013, the statement says.

It says Dyfed works full-time on the farm, alone with increasing frequency as the older business members are above retirement age, working “long hours out of necessity to undertake all the work associated with one of the largest flocks of sheep in Wales”.

“His working hours are extended further due to the fact that he lives remote (6kms) from the main block of land at Tyllosg, where Mynydd Du is situated in the centre of the farm. Travelling back and forth several times each day during lambing and other times during poor weather, to check on flock welfare is an arduous task and can be dangerous, particularly if driving when tired during inclement conditions.”

The statement adds: “The application seeks permission to repair the fire damaged dwelling at Mynydd Du and bring it back to serve a useful purpose to enable Dyfed to closely monitor the ewes, not only at lambing, but throughout the year when the flock is grazing on the adjacent common land.

“It will also enable Dyfed to be with his partner and young child on a more regular basis than simply at the end of a long day when he is away from their current home, tending the sheep at Mynydd Du.”

The application will be considered by park planners at a later date.
