A biofilm biofertilizer project offers a low-cost alternative to synthetic fertilizers

A unique suite of biofilm-forming plant growth promoting bacteria indigenous to the UK and adapted to its soils will improve soil quality and plant and crop health.

An innovative project that aims to provide UK farmers and growers with a sustainable and environmentally friendly nutrient management solution is underway following a partnership between industry experts.

The project, called ‘Biofilm Biofertiliser’, will develop a novel multi-species biofilm-based biofertiliser product that reduces the use of synthetic fertilisers by 40-50%.

By using a unique set of UK indigenous biofilm-forming plant growth promoting bacteria (PGPB), which is adapted to UK soils, it will improve soil quality and plant and crop health, resulting in a 20-30% yield increase.

Formulation types include water dispersible granules (WDG) and encapsulated options, which aim to improve nutrient availability, enhance soil health and encourage a stable biofilm with an expected minimum shelf life of up to 24 months.

Following funding from the UK innovation agency, Innovate UK, the project is being led by a consortium of partners including lead partner, Bionema Group, a world leader in developing biocontrol technology for crop protection and plant health management; CPI, responsible for process development and sample production for the UK field trials, and the UK Agri-Tech Centre, responsible for project management and dissemination/exploitation, ensuring end-user awareness and engagement.

As part of this project, three UK farmers and growers in the agricultural and horticultural sector will be provided with a nutrient management solution that offers a low-cost alternative to synthetic fertilisers, improves soil and plant health, increases crop yields by 20-30% and reduces nutrient runoff.

In addition, the innovative biofilm-based biofertiliser will be produced and manufactured in the UK, reducing reliance on imports from global suppliers.

Farmers and growers are faced with the challenge of reducing the use of synthetic fertilisers, as required by laws and regulations, while increasing food production using more sustainable organic farming methods to meet an ever-increasing global demand.

Potential impacts

Bionema’s technology will benefit farmers and growers by improving soil quality, plant health and yields, thereby integrating seamlessly into existing farming practices and leading to more sustainable agriculture, greater resilience and increased profits.

There are many economic benefits, including generating employment and income from new product formulations, establishing global partnerships and increasing export opportunities, while establishing the UK as a leader in biocontrol technology.

Farmers and growers will also contribute to reducing GHG emissions, improving air quality and reducing environmental pollution from nitrogen runoff.

In addition, the integration of technology will streamline farming practices, promoting sustainable agriculture and resilience, while innovation will boost the biocontrol and biofertilizer sector, encouraging a shift from synthetic to bio-based solutions.

The project aligns with UK and EU regulatory commitments to reduce synthetic fertilizers by 20% by 2030 and supports Sustainable Development Goals (SDGs) such as Zero Hunger, Good Health and Well-being, Responsible Consumption and Production and Life on Land.

The project plan

In the early stages of the project, partners will focus on developing, optimizing and validating formulations for the bacteria consortia, ensuring their stability, efficacy and ease of application.

The two main types of formulations that will be the focus are WDG and Encapsulation.

Laboratory testing will comprehensively evaluate the effectiveness of encapsulated WDG and PGPR formulations in promoting plant growth, enhancing nutrient uptake, and improving soil and plant health.

This evaluation includes measurement of seed germination, plant biomass, nutrient uptake, soil microbial activity, soil health indicators, and plant stress tolerance under controlled conditions.

Later in the project, the partners will look at testing the sprayability of the formulation, and this work aims to evaluate the spray characteristics, droplet size and droplet deposition on leaves of the formulations received earlier in the project.

The project combines cutting-edge expertise with conventional sprayers to evaluate spray characteristics and uses new technology to contribute to an innovative approach.

During the project, field trials for nutrient management will be conducted with the aim of evaluating WDG and biofilm-encapsulated biofertilizer formulations on various crops for efficacy and phytotoxicity on commercial farms during years two and three.

The trials will evaluate strawberries for yield, quality and health; potatoes for yield, size and vigor; wheat for yield, height and disease resistance; and ornamental plants for growth, flowering and aesthetics, compared to existing solutions.

Dr Minshad Ansari, CEO and Founder of Bionema Group, as lead SME partner for the Biofilm Biofertiliser project, said: “The Biofilm Biofertiliser project represents a significant step towards a sustainable and resilient agricultural future. By integrating cutting-edge biofilm technology with UK-specific microbial solutions, we empower farmers and growers to reduce their reliance on synthetic fertilisers whilst improving soil health and crop productivity. At Bionema, we drive innovation in biocontrol, biostimulants and biofertilisers, ensuring sustainable agricultural solutions are effective and economically viable for farmers and growers. This collaboration, supported by Innovate UK, brings together the expertise needed to transform nutrient management and set new standards for environmentally responsible farming.”

Kris Wadrop, Managing Director of Materials at CPI, said: “At CPI, we are committed to driving innovation in sustainable agriculture by supporting the development, scale-up and commercialisation of innovative technologies. The Biofilm Biofertiliser project is an exciting opportunity to develop an innovative solution to improve soil health and reduce reliance on synthetic fertilisers. By leveraging our expertise in engineering biology, formulation science and advanced manufacturing techniques, we aim to help bring this novel biofertiliser to market, helping UK farmers adopt more sustainable and productive farming practices.”

Richard Glass, Head of Innovation at the UK Agri-Tech Centre, said: “This project will provide vital support to farmers looking to increase the economic and environmental sustainability of crop production by reducing reliance on synthetic nitrogen fertilisers. This would enable a reduction in the cost of agricultural inputs, as well as reducing the carbon footprint of the cropping system. There are additional benefits with reduced field GHG emissions associated with synthetic fertilisers and improved soil health.”
