Phosphate replacement proposed

FUNGI could be used as a ‘bio-fertiliser’ with the potential to replace unsustainable mined phosphate in future, according to new research from the University of Cambridge.
The study shows that the interaction of roots with a common soil fungus changes the genetic expression of rice crops, triggering additional root growth that enables the plant to absorb more nutrients.
In addition to causing extra root growth, the mycorrhizal fungus also extends within crop roots, blooming within individual plant cells.
The fungus grows thin tendrils called hyphae that extend into surrounding soil and pump nutrients, phosphate in particular, straight into the heart of plant cells.
Plants ‘colonised’ by the fungi get between 70 to 100% of their phosphate directly from these fungus tendrils, an enormous mineral boost.
The researchers hope that the fungi could be used as a ‘bio-fertiliser’ that ultimately replaces the need to mine phosphate from the ground for industrial fertiliser.
Finding a replacement for mined phosphate is a critical problem as the fertiliser can cause pollution, and the big phosphate mines are now depleted to the point where they are expected to run out in the next 30 to 50 years.
“The big question we are trying to answer is whether and how we can make use of the biofertiliser capacity of mycorrhizal symbiosis in modern and more high input agricultural settings, meaning more intensive farming methods. We need alternatives to phosphate fertiliser if we are to feed growing populations,” said Dr Uta Paszkowski from the University of Cambridge’s, who co-authored the research.
Cereal root architecture involves a few big, thickset roots called crown roots, from which all the smaller lateral roots spread out into the different layers of soil.
Researchers found that plants colonised by mycorrhizal fungi have a different genetic expression which causes the cell walls within crown roots to soften, triggering the growth of many more lateral roots which are able to suck in more nutrients, contributing to a healthier plant with a higher yield.
This is in addition to the phosphate provided by the fungal tendrils, which in effect act as extra roots themselves (in return for which, the fungus absorbs carbohydrate from the plant).
“Plant roots that have the capacity to explore the widest soil area absorb the most nutrients as a consequence and so are likely to have a greater crop yield. By finding out which parts of the genome are responsible for the best plant root systems we can start breeding for the best root architecture,” said Ms Paszkowski.
“Designer crops with the best possible root systems will mean greater crop yield, which means more people fed.”
The main hurdle for researchers to overcome is the self-regulation of plants, which means the fungi cannot be tested on an industrial scale alongside traditional fertiliser.
“Plants monitor their own nutritional state. If a plant has enough phosphate it will not allow fungus to enter root – so at the moment it’s one or the other. We are working on ways to circumvent this blockage so we can allow symbiosis to contribute in agricultural practices in better developed countries,” said Ms Paszkowski.
Mycorrhizal fungi are extremely common in all soils around the world, and are an ingredient in many ‘bio’ plant foods found in domestic garden centres, but have yet to be used for industrial agriculture.

A PEMBROKESHIRE man has been found not guilty of breaching a restraining order after being accused of referencing a protected individual in a Facebook post.

Philip Stoddart, 58, of Monkhill Farm, St Ishmaels, appeared at Haverfordwest Magistrates’ Court on Monday (Jan 20) to face the charge. The prosecution, led by Ann Griffiths on behalf of the crown, alleged that between December 4 and December 13, 2023, Stoddart made a Facebook post that, by inference, referred to a person he was prohibited from contacting under a restraining order imposed by Swansea Crown Court on April 16, 2021.

The restraining order, issued under Section 360 of the Sentencing Act 2020, barred Stoddart from making any form of contact with her.

Prosecutors argued that the Facebook post constituted a breach of the order, contrary to Section 363 of the same act.

Stoddart denied the allegations and entered a not guilty plea during a prior hearing on October 1, 2024.

Magistrates Professor N. Negus, Mr. J. Steadman, and Mrs. J. Morris presided over the trial, which concluded on Monday.

After reviewing the evidence, the bench found Stoddart not guilty, dismissing the case.

The dismissal brings to a close legal proceedings that had been ongoing for over a year.

FARMERS in Wales are being called to apply for the next round of funding for on-farm trials.

The Farming Connect initiative, which has funded projects such as growing lucerne in Brecon, is inviting applications for the Try Out Fund.

The new application window opens on January 27, 2025, and will run until February 17.

Successful applicants will be awarded up to £5,000 to help fund trials that experiment with new ideas on their farms.

The last round of funding supported several projects, including integrated pest management at a pick-your-own strawberry enterprise.

Menna Williams, the Farming Connect project lead, said: “Farming Connect has developed the Try Out Fund to address specific local problems or opportunities with the aim of improving efficiencies and profitability within agricultural businesses whilst protecting the environment.”

She added: “There are many changes on the horizon for agriculture, and now is a great time for farm businesses to explore an idea that could benefit them, allowing farms to tackle ‘real’ problems or check if a research idea works in practice.”

The fund is open to individuals or groups of up to four farmers and/or growers in Wales who have identified a local or specific problem or opportunity.

Ms Williams said: “Because these ideas are initiated by farmers themselves, they are really passionate about them, giving them 100 per cent effort right from the start.”

Projects should focus on enhancing production efficiencies and profitability while ensuring environmental protection through adherence to sustainable land management principles.

A guidance handbook is accessible on the Farming Connect website, providing support for farmers in outlining their projects and completing the application process.

To apply, individuals must be registered with Farming Connect and capable of finishing their projects by January 2026.

Ms Williams explained: “Funding can be used for technical assistance, sampling, testing and other reasonable expenses such as those relating to short-term hire of specialist equipment or facilities directly relating to the project.”

The findings will be shared with other producers in Wales by collaborating with a Farming Connect team member.

Interested parties can apply on the Farming Connect website.

WITH Farming Connect-funded trials ranging from growing lucerne in Brecon to establishing sunflowers as a companion crop with maize, farmers are being invited to apply for the next round of funding from the initiative that brought these projects to life.

The new application window for the Try Out Fund opens on 27January2025 and will run until 17 February. Successful applicants will be awarded up to £5,000 to help fund on-farm trials that experiment with new ideas. The last round of funding saw farmers supported for several projects including integrated pest management at pick your own strawberry enterprise.

Project lead Menna Williams of Farming Connect said the aim is for farmers to compare different treatments or management systems – the project is not intended to fund new equipment she stressed.

“Farming Connect has developed the Try-Out Fund to address specific local problems or opportunities with the aim of improving efficiencies and profitability within agricultural businesses whilst protecting the environment,’’ she said. “There are many changes on the horizon for agriculture, and now is a great time for farm businesses to explore an idea that could benefit them, allowing farms to tackle ‘real’ problems or check if a research idea works in practice.’’

The fund is open to individuals or groups of up to four farmers and/or growers in Wales who have identified a local or specific problem or opportunity.

“Because these ideas are initiated by farmers themselves, they are really passionate about them, giving them 100% effort right from the start,’’ said Ms Williams.

Suitable projects must aim to improve production efficiencies and profitability whilst protecting the environment by aligning with sustainable land management outcomes. A guidance handbook is available on the Farming Connect website to help farmers scope their project and complete the application form.

Applicants must be registered with Farming Connect and be able to complete their projects by January 2026.
