Global growth, local proof: field-tested biostimulants you can trust

Trial Data

Maxstim potato field trials

Why farmers are turning to biostimulants

Across the globe, growers are turning to biostimulants to increase yields, reduce costs, and build resilience to stress. In just five years, global use has nearly doubled — and the trend shows no sign of slowing:

It’s working.

  • Global biostimulant market in 2020: $2.5 billion
  • 2025 value: $4.5 billion
  • Forecast for 2032: $9.75 – $10.25 billion in value
  • In Europe, adoption has jumped from 15–20% to 30–40% of fruit and veg acres

This isn’t a passing trend. Biostimulants have gone from a “maybe” to a “must-have”, especially when they’re field-proven, like Maxstim.

What are biostimulants, and why the rapid growth?

Unlike fertilisers, biostimulants don’t add nutrients. Instead, they make plants more efficient at using what’s already in the soil. The result? Healthier crops that can withstand drought, heat and other stressors, with improved uniformity and quality.

Maxstim’s advantage: Amphenox™ technology

Maxstim’s complex biostimulants are built with patented Amphenox™ compounds that deliver:

  • Enhanced photosynthesis
  • Better nutrient uptake and conversion
  • Improved drought and stress tolerance
  • More uniform growth and market-grade finish

Field-proven results in the UK

We’ve spent years running real-world trials across the UK, focused on crops that demand results.

Potatoes (UK, 2022-2024)

  • Up to 10.6% more marketable yield
  • £600–£885/ha in added profit
  • Skin finish improvement = premium market access
  • 36 commercial trials across 16 potato varieties
  • 4.24 t/ha average yield gain with 99.98% statistical confidence

“Every year has been tough, and every time Maxstim increased my yields.”

— Tony Parr, Suffolk potato grower

Onion Trials (UK, 2022–2024)

  • 18 trials on Red and Brown onions (e.g. Red Baron, Red Tide, Donna, Numbito)
  • 7.6% increase in marketable yield (50–80mm)
  • £400–£600/ha extra margin after product cost
  • Consistent yield even with 20% less fungicide use

Turf (Sports, Amenity & Sod Farms)

  • Denser roots and stronger recovery
  • Greener, healthier turf under wear and weather
  • Reduced synthetic nitrogen requirements

What Maxstim can deliver for you

Crop  What You Can Expect
Potatoes Bigger, more uniform tubers. Improved skin finish.
Onions Stronger roots. Better sizing. Weather resilience.
Turf Faster recovery. Better colour. Less reliance on N.

Protocols are flexible: in-furrow, pre-emergence, foliar or with starter fertiliser. We’ll help you decide what’s best for your field and timing.

Why growers are switching to Maxstim

  • Scientifically validated in UK trials
  • Compatible with integrated crop management
  • Helps reduce dependency on agrochemicals
  • Proven economic return in real-world conditions

The bottom line: this is a smarter way to grow.
