In the search for healthier soil, stronger crops, and lower chemical use, one name keeps coming up again and again: Bacillus amyloliquefaciens.
This remarkable soil bacterium isn’t just another biofertiliser ingredient. It’s a proven plant growth promoter, natural disease fighter, and sustainability hero, and it’s already working wonders on real farms.
Tired of watching yields suffer from poor soils, disease pressure, or climate stress?
There’s a microscopic ally already working underground to fix it , and it’s called Bacillus amyloliquefaciens.
This powerful bacterium helps your crops grow stronger roots, fight off disease naturally, and get more from every drop of fertiliser, even in poor or stressed soils.
The best part? It’s natural, safe, and already delivering results on real UK farms.
What Is Bacillus amyloliquefaciens?
Bacillus amyloliquefaciens is a naturally occurring, spore-forming bacterium found in the soil and plant roots. It’s closely related to B. subtilis but with its own unique superpowers.
In farming, it belongs to a class of microbes known as Plant Growth-Promoting Rhizobacteria (PGPR). That means it supports healthy crop growth and root development, especially under stress like drought, disease, or poor soil fertility.
Key Facts
What is it?
Bacillus amyloliquefaciens is a beneficial soil bacterium and plant growth-promoting rhizobacterium (PGPR).
Why it matters in arable farming:
It boosts plant health, improves yields, suppresses disease, and reduces the need for chemical fertilisers and pesticides.
Main benefits:
✔ Improves nutrient uptake (N, P, Fe)
✔ Produces natural antibiotics against crop diseases
✔ Helps crops cope with drought, salinity, and heat
✔ Forms protective root biofilms
✔ Safe for organic and conventional farming systems
Used in:
Wheat, barley, maize, potatoes, tomatoes, peppers, cucumbers, lettuce, and more.
Present in BactoTech products.
What Can It Do for Arable Farmers?
Here’s what makes Bacillus amyloliquefaciens so effective in field conditions:
1. Disease Control Without Chemicals
This bacterium produces a powerful mix of antibiotic-like compounds, including surfactins, iturins, bacillaene, and fengycins, that naturally suppress common fungal and bacterial diseases such as:
- Fusarium spp.
- Rhizoctonia solani
- Sclerotinia sclerotiorum
- Pythium root rot
- Potato common scab (Streptomyces scabies) (source)
2. Stronger Roots and Better Nutrient Uptake
Bacillus amyloliquefaciens solubilises phosphates, improves nitrogen use efficiency, and helps plants absorb essential micronutrients like iron and zinc. This leads to:
- Better root development
- Faster early growth
- More resilient crops in tough soil
3. Stress Tolerance in Harsh Environments
B. amyloliquefaciens helps plants tolerate salinity, drought, and heat by producing natural stress-alleviating compounds like:
- Osmolytes (to help retain water)
- ACC deaminase (reduces stress-induced ethylene levels)
- Biofilms (protect roots and improve microbial colonisation) (source)
4. Safe and Sustainable
It’s 100% natural, non-GMO, and doesn’t leave harmful residues. That means it’s:
- Safe for soil, water, bees, and humans
- Perfect for regenerative and organic farming
- Long-lasting due to its spore-forming nature (ideal for dry formulations)
Real Research, Real Results
Multiple studies back up what farmers are seeing in the field:
- Wheat and barley showed higher germination and biomass in salinity-stressed soils
- Tomatoes, lettuce, and pepper crops treated with Bacillus amyloliquefaciens had better root systems, higher nutrient content, and improved fruit quality
- In potatoes, it reduced soft rot and common scab, leading to improved yield and tuber quality (source)
Why Farmers Are Switching
Chemical fertilisers and pesticides may offer short-term boosts but often degrade soil health over time. In contrast, Bacillus-based biofertilisers like Bacillus amyloliquefaciens:
- Boost yields while reducing chemical inputs
- Improve long-term soil health
- Align with new environmental regulations
- Build resilience against disease and weather stress
Final Thoughts
Bacillus amyloliquefaciens isn’t just a helpful microbe, it’s a game-changer for modern arable farming. As part of BactoTech’s natural biopreparation lineup, it gives farmers the tools to grow strong, healthy crops while protecting the planet and future generations.
