Empowering Growth: How Biostimulants Are Shaping the Future of Sustainable Agriculture

28 April 2025, Israel: The quest for solutions that ensure food security while minimizing environmental impact is at the heart of modern farming. Biostimulants have emerged as key players in the shift toward more sustainable agriculture— enhancing plant health, boosting resilience, and improving productivity in ways that traditional inputs cannot.

Plant biostimulants complement traditional fertilizers by stimulating natural processes within the plant. This includes improving nutrient uptake, enhancing stress tolerance, and supporting overall vigor. These innovations offer farmers a powerful tool for addressing both the challenges of climate change and the demands of a growing global population.

The Transformative Effects of Biostimulants

The benefits of agricultural biostimulants go far beyond promoting growth. They influence plant vitality, stress resilience, root development, and even the microbial health of soils— providing a foundation for sustainable farming practices.

Boosting Plant Vitality and Crop Yields

One of the most significant advantages of biostimulants is their ability to improve plant vigor, translating into higher yields and better crop quality. These benefits are particularly valuable for high-value horticultural crops, where quality directly impacts profitability.

Recent research shows that plant stimulants can activate natural physiological processes— such as photosynthesis and nutrient assimilation— to help crops reach their full genetic potential.

“Biostimulants are essential for maximizing the genetic potential of plants,” says Dr. Eduardo Lopes Cancellier, ICL Biostimulants Agronomy Specialist.

This increased efficiency supports the production of healthier, more nutritious food while reducing reliance on synthetic inputs.

Enhancing Stress Resilience

Unpredictable weather patterns, prolonged droughts, temperature extremes, and high soil salinity are becoming more common across global farming regions. These abiotic stressors threaten crop yields and long-term food security.

Biostimulants help plants cope by enhancing their internal defense mechanisms— supporting natural metabolic pathways that regulate stress responses.

“The ability of biostimulants to enhance stress tolerance is indispensable in today’s agricultural landscape,” notes Dr. Eduardo Cancellier.

For example, ICL has developed a foliar biostimulant fertilizer—BIOZ Keep Green—designed to protect coffee trees from excessive solar radiation. In field trials, it delivered an average productivity increase of seven sacks per hectare, offering growers a reliable return on investment and improved crop resilience. ICL is also evaluating this solution for other crops.

Stimulating Root Growth and Improving Nutrient Use Efficiency

A strong root system is the foundation of healthy plant development. Biostimulants for plants play a crucial role in stimulating root growth, improving the plant’s ability to absorb water and nutrients— even in poor soil conditions.

“Improved root growth leads to better nutrient and water uptake, significantly enhancing the overall health and stability of the plant,” explains Dr. Eduardo Cancellier.

By enhancing nutrient use efficiency, biostimulants help farmers get more out of every input, contributing to sustainable production and reduced environmental impact. Two examples from ICL’s BIOZ™ line—BIOZ™ Topaz and BIOZ™ Nephrite—support natural nitrogen fixation throughout the crop cycle, helping reduce dependence on synthetic crop protection products and lowering associated carbon emissions..

Enhancing Soil Health

Healthy soil is a non-negotiable pillar of long-term agricultural sustainability. Biostimulants support soil health by stimulating beneficial microorganisms and improving nutrient cycling.

“Biostimulants enrich the soil ecosystem, making it more conducive for plant growth and resilience,” says Dr. Eduardo Cancellier.

ICLs BIOZ Diamond, a natural complex blend of biostimulants, works by boosting microbial diversity and activity. The result is stronger root systems, improved nutrient uptake, and a thriving soil environment that supports both current and future crop cycles.

Navigating Challenges with Innovation

While the potential of biostimulants is widely recognized, the path to broader adoption still comes with challenges. Scientific complexity, regulatory compliance, and cost barriers can slow innovation— but they also present opportunities for long-term impact.

Overcoming Scientific and Practical Hurdles

Each crop and environment presents unique demands. Biostimulants for seed treatment, foliar application, or soil incorporation must be tailored for effectiveness. Understanding how biostimulants interact with plant metabolism under diverse conditions requires deep scientific exploration and extensive field testing.

“Each crop and environment demands a unique approach with biostimulants,” says Dr. Eduardo Cancellier.

Ongoing research is expanding knowledge of plant-microbe interactions, stress signaling pathways, and how to optimize biostimulant application timing. Innovations like encapsulated delivery using natural polymers are already showing promise in improving field stability and performance.

Economic and Regulatory Opportunities

The regulatory environment is evolving to support biostimulant use while ensuring product safety and efficacy. For example, the EU’s Fertilizing Products Regulation (FPR) provides clear definitions and guidelines for agricultural biostimulants— pushing the industry to meet higher standards.

“Regulatory frameworks push us to prove the effectiveness of our biostimulants, aligning product development with the highest industry standards,” says Dr. Eduardo Cancellier.

ICL embraces this rigor, conducting extensive trials and submitting evidence-backed claims to meet both regulatory and farmer expectations. These efforts are part of a broader push to develop next generation biostimulants that align with environmental and market demands.

Biostimulants: A Pivotal Role in Sustainable Farming

As agriculture adapts to the challenges of climate change, resource scarcity, and the need for higher productivity, biostimulants are stepping into the spotlight. These innovative tools offer a sustainable path forward— enhancing plant performance while minimizing environmental impact.

Biostimulants are not simply alternatives to conventional inputs—they’re part of a broader shift toward regenerative and precision agriculture. From improving crop yields and stress tolerance to enriching soils and boosting nutrient efficiency, their role in modern farming is becoming indispensable.

“The potential for biostimulants to revolutionize farming is immense, and at ICL, we are committed to unlocking this potential,” concludes Dr. Eduardo Cancellier.

ICL continues to invest in biostimulant innovation through robust research, global field trials, and sustainable product development. By empowering growers with data-driven, effective, and environmentally responsible solutions, ICL is helping build a future where agriculture can thrive— responsibly and resiliently.
