Are Biosolutions The Future Of Sustainable Agriculture?

Farmers in the UK are between a rock and a hard place. On one side, the global population continues to grow at an alarming rate and farmers must work harder to feed these hungry mouths. On the other, the pressure of climate change not only impacts our ability to farm but also places huge demands on cutting the environmental footprint of agriculture. With these competing demands, farmers must find smarter solutions to continue to farm effectively and profitably.

One of the most talked-about developments that are part of the solution to this problem are biosolutions. These natural or nature-derived products help to support plant growth, boost the resilience of crops and, critically, reduce the need for synthetic chemistry.

But, what exactly are biosolutions and are they the future of sustainable farming in the UK? In this blog we ask what are biosolutions? Why biosolutions matter for UK agriculture?

What are the benefits of biosolutions? And, what are the challenges of using biosolutions? Crucially we also explore the different types of biosolutions and their uses across your farm.

What are biosolutions in agriculture?

Definition and scope of biosolutions

Biosolutions are a varied and growing group of agricultural products that are derived from naturally occurring microorganisms, plant extracts, or biological processes. They work by triggering the natural mechanisms within the plant or soil to boost natural defences rather than using chemicals that directly attack pests or diseases.

Biosolutions products include biostimulants, biocontrol solutions and biofertilisers and all of them use biology as the driving force to enhance the efficiency of crops and soils. Unlike the majority of synthetic products which are specifically designed for a single purpose, biosolutions can provide a range of benefits. This is because they work to strengthen the crop’s natural biology and this helps to boost resilience, nutrient uptake, and soil function over time.

How biosolutions differ from conventional crop protection

While traditional crop protection solutions have chemicals that act directly on the challenges facing plant, like targeting a pests nervous system, biosolutions take a different approach. Instead of attacking the pest directly, a biosolution will support the plant to strengthen its natural defences. This includes making it stronger by making more nutrients available and promoting soil health or initiating the plant’s own defence mechanisms before disease or pests can take hold.

However, for now, biosolutions can’t completely replace the conventional chemistry most farmers know and understand. Instead, biosolutions act as a compliment to these inputs but bring significant benefits as it enables farmers to reduce input intensity, improve efficiency, and extend the life of existing chemistry.

Why biosolutions matter for UK farming

Driving more sustainable crop production

Every farm in the UK is facing huge pressure to improve sustainability, whether that’s from the Government or food groups who rely on the supply chain to help them meet ambitious net zero targets. From reduced emissions to improved soil health and biodiversity gains, biosolutions can be a valuable tool in a farmers arsenal as they provide a relatively simple route to achieving these goals without having to make major changes to existing agricultural operations. Biosolutions are key to working in harmony with natural processes and this means you can maintain, or even grow, your productivity while making measurable improvements in your environmental impact.

Supporting net zero and environmental goals

The UK Government has a big ambition for the country to be net zero by 2050 and the UK agricultural sector also has a target to reach net zero emissions ten years earlier than that. This means agricultural priorities and standards are being reshaped dramatically but biosolutions will play a major role in our net zero future.

Products that help to boost nutrient uptake, enhance soil carbon sequestration or reduce the amounts of inputs will all help to directly reduce greenhouse gas emissions. Similarly, these new biological pest controls can limit the need for repeated chemical applications in the field, lowering fuel use and the associated emissions.

With many farmers either required to meet environmental targets from their supply chain or being engaged in environmental stewardship schemes, biosolution technologies also align with the direction of policy which aims to create greater biodiversity, improved soil health, and cleaner watercourses.

Reducing reliance on synthetic chemistry

As regulations tighten, fewer and fewer crop treatments are becoming available to farmers. This challenge is also coupled with the approval of new products becoming increasingly complex and taking much longer to get to market. This means farmers have fewer options to combat the disease and pest pressures facing their crops. With biosolutions, farmers have new ways to diversify their pest and disease management strategies.

By complimenting the available chemicals, or even offering alternatives, farmers can find new ways to help their crops thrive and survive or extend the life of the chemistry in the field.

From a public relations perspective, biosolutions are another key bonus. There is growing consumer demand for reduced chemical use and more environmentally responsible practices in food production. Biosolutions are a positive story in this respect, offering natural solutions that bring a range of environmental benefits and boost public confidence in the food chain.

The main categories of biosolutions

While the biosolutions market is expanding rapidly, most products fall into three main categories. These are …

• Biostimulants to enhance crop growth and resilience Biostimulants do exactly what they say on the tin and stimulate the plant’s natural biological processes. This can take many forms from enhancing nutrient uptake, improving stress tolerance, fighting disease or boosting yield potential. These biostimulants aren’t a replacement for fertilisers, but help to make nutrient use more efficient, reducing the need for expensive applications. For farmers, this means crops a better prepared to face the increasingly variable weather conditions battering the UK agricultural sector and they also get a much more efficient return on their inputs.
• Biocontrol solutions for pest and disease management Biocontrol products make use of natural enemies or biological mechanisms to manage pests and diseases. This might include beneficial fungi that suppress soilborne pathogens or bacteria that prevent disease establishment on leaves. These products are becoming more sophisticated and can be integrated effectively into existing IPM strategies - particularly in protected crops, and increasingly in broadacre systems as innovation develops.
• Biofertilisers and soil health products This group of biosolutions are dedicated to boosting beneficial microorganisms that improve nutrient cycling and soil structure. They unlock the nurtrients that are already present in the soil and help make them readily available to the crop. These nutrients are released in a way that helps to create steady, balanced growth in the crop. With fertiliser costs crippling many farms, biofertilisers and microbial soil enhancers help farmers to make their resources go further while also helping to improve the long-term health of the soil, protecting the future of the farm.

Benefits of biosolutions for farmers

Improving crop resilience to stress

Climate change and weather extremes are, arguably, becoming one of the biggest challenges facing farming today. From extreme droughts to constant deluges of rain, managing crops in these conditions is an increasing issue. With biostimulants however, we can use products such as microbial inoculants or plant extracts to help improve a crop’s ability to recover from environmental stress. These solutions help to build stronger root systems, drive more efficient nutrient uptake and create better overall vigour ensuring crops can endure the worst of the British weather to come.

Enhancing efficiency of inputs

Perhaps the biggest benefit of biosolutions is their support in improving the way plants access and use nutrients. This means biosolutions can make existing inputs work harder. By getting more yield from the same amount of nitrogen, or reducing the number of inputs required across the season, farmers can make important marginal gains that can quickly add up This ensures we can continue to farm sustainably and profitability as we move towards the future.

Supporting long-term soil health

Soil health has been a key focus for a number of years now after fears grew that the land beneath our feet was becoming exhausted. The health of the land is the very foundation of farming and biosolutions help to build soil biology. By using products such as microbial inoculants, compost teas, or organic biofertilisers, we can help to create better soil structure, increased microbial activity, and improved nutrient cycling. While these will deliver benefits to the crop in the ground now, it also delivers valuable long term benefits by creating healthier farm ecosystems that will deliver more consistent yields and greater resilience in the future.

Challenges to wider adoption of biosolutions

While it is clear that biosolutions can bring a wealth of benefits and have potential for all growing operations, there are still some practical challenges to wider use across the agricultural sector.

Ensuring consistency and reliability

Consistency in the performance of biosolutions can be an issue. This is because biological products are sensitive to environmental conditions. Temperature, moisture and soil biology can all impact performance and this means the outcome from biosoltuions can sometimes be varied. However, as research into biosolutions continues at a breakneck pace, consistency is improving. For many growers, the jury is still out and they are waiting for more data and farm-based evidence before they have full confidence in this approach.

Market development and availability in the UK

Biosolutions have soared in popularity across Europe but the UK is lagging behind at this stage. A limited number of suppliers are providing biosolutions in the UK but there are also a diverse range of products and this can make it hard for farmers to decide on the best solution. We are starting to see a rage of independent trials and knowledge-sharing networks appearing around the UK and this, coupled with trusted agronomy advice, will be key to building a strong appetite for biosolutions.

Understanding regulation and product claims

Another key challenge for the biosolutions market is a regulatory framework that is still evolving to understand and manage these products. Biostimulant products can fall under different classifications, from biostimulants and biopesticides to even fertiliser additives, and this means each will haqve a different registration pathway and different rules. This confusion makes it challenging to compare biosolutions and the claims they can make. As regulation develops, it will hopefully make it far simpler for farmers to make informed decisions.

The future of biosolutions in agriculture

Innovation and new product development

As we’ve said, the development of biosolutions is happening quickly and we are seeing a range of new solutions coming down the innovation pipeline, from next-generation microbial inoculants to digital tools that guide application timing. The good news is that a host of UK research institutions, agribusinesses and ag-tech start-ups are getting involved and that will ensure future solutions are tailored to UK conditions and crop types.

Integration with conventional agronomy practices

For biosolutions to succeed, they will need to be incorporated into existing agricultural practices rather than replace them. This means farmers need to work to understand how biosolutions fit into their nutrient programmes, crop protection plans and rotation strategies to maximise yields and protect soil health. When used as part of a holistic system, biosolutions will be a valuable tool in helping to grow or maintain yields while steadily improving environmental outcomes.

Opportunities for UK growers With the biosolutions sector now rapidly advancing in this country, it presents a great opportunity for UK farmers and growers to stay ahead both of competitors and sustainability targets. With retailers and food processors increasingly setting new environmental expectations for supply chains, biosolutions not only help demonstrate a proactive approach but also help with farm assurance and sustainability reporting.

Conclusion: A balanced approach for a sustainable future

Biosolutions are not the magic formula that will solve all of our agricultural woes or a replacement for conventional inputs. But, they are a powerful new tool for farmers and growers. They compliment and enhance existing farming practices and will be a key driver as we all work toward the new agricultural future laid out for the UK.

By integrating biosolutions into our crop management systems, farmers can improve resilience, efficiency, and sustainability, while maintaining the productivity that underpins every successful farm business. Research is moving fast and the evidence is building.

This means biosolutions will be playing a pivotal role in creating a more sustainable, regenerative future for UK agriculture. If you’d like to learn more about biosolutions, speak to your Agrii agronomist.
