What are biostimulants and why are they crucial for potatoes?
Scientific research

In the face of rising global food demand and environmental challenges, farmers are turning to innovative, sustainable solutions to maximise crop productivity. One of the most promising tools in modern agriculture is biostimulants—natural products designed to support plant growth, resilience, and efficiency.
What are biostimulants?
Biostimulants are substances or microorganisms that enhance a plant’s natural processes, improving nutrient uptake, stress tolerance, and overall health. Unlike fertilisers, which supply nutrients directly, biostimulants work biologically to make plants more efficient at using the resources available to them.
There are two main types of biostimulants: microbial (e.g., beneficial bacteria and fungi) and non-microbial (e.g., seaweed extracts, humic acids, and flavonoid-based complexes). Flavonoid-based biostimulants, like Maxstim’s Agriculture+, have shown exceptional potential in potato farming by promoting growth and resilience in challenging conditions.
Why are biostimulants important for potatoes?
Potatoes are one of the world’s most important food crops, but they require significant inputs like water, fertilisers, and pesticides to maintain high yields. As environmental pressures grow, farmers need solutions that improve efficiency without compromising productivity.
Here’s how biostimulants benefit potato farming:
- Improved nutrient use: Biostimulants enhance the plant’s ability to absorb and utilise nutrients, reducing dependency on fertilisers.
- Stress tolerance: Flavonoid-based biostimulants protect potatoes from drought, temperature extremes, and other stresses, ensuring stable yields in variable conditions.
- Sustainable yield increases: Studies, including recent scientific research by Maxstim, show significant yield boosts with biostimulants—up to a 33% increase in tuber weight in controlled trials.
By combining these benefits, biostimulants not only improve productivity but also help reduce environmental impact, making them essential for sustainable potato farming.
A future with biostimulants
As the agriculture industry strives to balance productivity with sustainability, biostimulants are emerging as a game-changing innovation. They are empowering farmers to grow more resilient crops, produce higher yields, and reduce resource consumption. For potatoes, a staple crop feeding millions globally, biostimulants are more than a tool—they’re a necessity for securing future food supplies.
