PSI® Technology: Deep Understanding of Marine Bioactives

PSI® Technology: Harnessing the Power of Marine Bioactives

The ocean is one of nature’s most powerful yet underutilised resources for agriculture. Within its depths are marine organisms that have evolved to thrive in harsh, ever-changing conditions. Among these is the brown seaweed Ascophyllum nodosum, a unique species packed with natural compounds that can dramatically influence plant health, growth, and resilience.

PSI® Technology was developed to unlock this potential. By combining advanced science with sustainable sourcing, Brandon Bioscience has created a platform that transforms marine bioactives into precision biostimulants capable of meeting the demands of modern farming. This deep understanding of marine bioactives ensures that every product is purposeful, consistent, and designed to solve real agricultural challenges.

Why Marine Bioactives Are Vital for Modern Agriculture

Agriculture today faces unprecedented pressures: climate change, declining soil health, limited freshwater availability, and growing regulatory restrictions on fertilisers and crop protection products. Farmers are expected to increase yields while reducing inputs, a balance that is difficult to achieve with traditional tools alone.

Marine bioactives provide a natural, sustainable solution. These compounds can stimulate plant physiology at a cellular level, improving nutrient use efficiency, water retention, and tolerance to stress conditions such as drought, salinity, and heat. When harnessed correctly, they enable crops to do more with less, supporting both productivity and environmental stewardship.

From Raw Material to Precision Biostimulant

Not all seaweed-based products are the same. While seaweed has long been used in agriculture, raw extracts often lack consistency and predictable results. This is because the beneficial compounds must be carefully identified and extracted for optimal activity.

PSI® Technology goes far beyond generic seaweed extracts. It begins with sustainable harvesting of Ascophyllum nodosum, followed by proprietary extraction methods optimise the bioactives. Each stage of production is carefully monitored, ensuring that the final product contains the exact molecular profile needed to achieve targeted agronomic outcomes. The result is a precision biostimulant, backed by science, that delivers measurable benefits in the field.

The Science Behind Marine-Derived Compounds

Unique Properties of Ascophyllum nodosum

Ascophyllum nodosum thrives in intertidal zones where it is exposed to extreme stress: fluctuating salinity, intense UV radiation, and constant changes in temperature and water availability. To survive, it has unique compounds that regulate its internal water balance, repair cellular damage, and maintain energy production. These same compounds, when applied to crops, stimulate similar mechanisms, helping plants cope with agricultural stress factors.

Bioactive Molecules and Their Role in Plant Physiology

Among the most important marine bioactives are marine carbohydrates:

These include alginate, fucoidan and laminarin, each with key roles in nutrient use efficiency, improving quality traits and increasing tolerance to abiotic stresses.

By targeting these compounds, PSI® Technology enables crops to respond dynamically to environmental challenges, leading to improved resilience and performance.

Challenges in Unlocking Bioactive Potential

Marine bioactives are complex. If extracted incorrectly or inconsistently, it will result in limited and incosistent performance when applied in field. Additionally, batch-to-batch variability in raw material quality can lead to inconsistent results in the field.

These challenges have historically limited the agricultural industry’s ability to fully capitalise on seaweed’s potential. PSI® Technology was created to solve this problem, providing a standardised, scientific framework for developing marine-based products with precision and repeatability.

How PSI® Technology Maximises Bioactive Efficiency

Precision Extraction for Targeted Results

The extraction process is at the heart of PSI® Technology. Using carefully controlled parameters, such as temperature, pH, and extraction time, Brandon Bioscience ensures that the most valuable compounds are released and preserved. This approach creates extracts with defined molecular signatures, each tailored to specific outcomes like drought tolerance, salinity stress management, or nutrient use efficiency.

Consistency and Quality Through Rigorous Analysis

Every batch of product undergoes rigorous physicochemical and bioactivity analysis. This ensures uniformity across production runs and provides a direct link between the product’s composition and its field performance. For growers, this means confidence that the product will deliver reliable results season after season.

Real-World Benefits of Marine Bioactives

Improving Stress Tolerance and Crop Resilience

Field trials with PSI® Technology products have demonstrated remarkable improvements in crop resilience. For example, products targeting drought stress have been shown to increase relative water content in plant tissues, improve stomatal control, and reduce yield losses during dry periods. Similarly, products designed for salinity stress have helped crops maintain ionic balance, protecting roots and shoots from sodium toxicity.

Enhancing Nutrient Uptake and Yield

Marine bioactives also play a key role in optimising nutrient use efficiency. By stimulating root growth and upregulating nutrient transporter genes, they allow crops to absorb more nutrients from the same amount of fertiliser. This not only boosts yield but also reduces environmental runoff and waste.

Sustainability Through Marine-Based Innovation

Sustainability is at the core of PSI® Technology. By enabling crops to thrive with fewer external inputs, marine bioactive-based solutions help reduce agriculture’s environmental footprint. Sustainable harvesting practices ensure that marine resources are protected, while the reduced reliance on fertilisers and irrigation supports global goals for climate-resilient food production.

As agriculture faces increasing scrutiny from regulators and consumers alike, PSI® Technology provides a pathway to sustainable intensification, where farmers can grow more food while preserving the ecosystems that support life.

Why Deep Understanding Leads to Reliable Performance

Many biostimulant companies claim to use seaweed, but without a deep understanding of its chemistry and physiology, the results are often inconsistent. Brandon Bioscience’s approach is different. By combining decades of research with cutting-edge technology, the company has created a platform where every decision, from harvest to field trial, is driven by data and scientific insight.

This depth of understanding is what allows PSI® Technology to deliver products that farmers can trust: solutions that are effective, repeatable, and aligned with the future of sustainable agriculture.
