Bacillus mucilaginosus: 

Powerful Biofertilizer for Sustainable Agriculture

Bacillus mucilaginosus (formerly Paenibacillus Mucilaginosus) is a potent agricultural biofertilizer that naturally unlocks insoluble potassium (K), phosphorus (P), and silicon (Si) for plant absorption. This soil inoculant improves soil structure, boosts plant stress tolerance, and promotes root growth—offering a natural, sustainable alternative to chemical fertilizers. Benefits include:

  • Unlocks mineral-bound nutrients: Potassium, Phosphorus, Silicon
  • Boosts micronutrient availability: Fe, Zn, Mn, Cu, Ca, Mg, Mo, S
  • Improves soil structure and moisture retention
  • Enhances plant resilience to drought and environmental stress

This naturally-occurring biostimulant enhances soil fertility and crop growth. Its ability to solubilize potassium, phosphates, and silicates makes it an important tool for boosting plant nutrition while reducing reliance on synthetic fertilizers. Additionally, this plant growth-promoting rhizobacteria (PGPR) significantly enhances micronutrient availability, unlocking essential elements including Silicon, Calcium, Iron, Zinc, Manganese, Copper, Magnesium, Sulfur, and Molybdenum. This supports optimal plant metabolism and defense mechanisms against environmental stressors. 

Potassium Solubilization
Bacillus mucilaginosus functions as a potassium-solubilizing bacterium, releasing plant-available potassium from minerals like feldspar and mica. This natural process enhances soil fertility, strengthens root systems, and builds plant resilience against drought and environmental stressors. Growers incorporating our B. mucilaginosus biofertilizer into their soil management practices reduce chemical fertilizer dependence while improving soil health and crop performance.

Phosphate and Silicate Solubilization
Bacillus mucilaginosus is a bacterial biostimulant that functions as both a phosphate-solubilizing and silicate-solubilizing microorganism, offering significant benefits for agricultural applications. By breaking down insoluble phosphate and silicate minerals in the soil, it makes these critical nutrients available to plants.

This soil probiotic releases phosphorus from bound soil minerals, promoting robust root development while simultaneously unlocking silicon from insoluble compounds, enhancing plant cell wall strength. Crops experience improved disease resistance, enhanced structural integrity, and greater stress tolerance through increased silicon uptake. 

Enhanced Macro and Micronutrient Availability
The soil inoculant supports organic and sustainable farming by improving the transport and availability of many key nutrients, including:

Improved Soil Structure
This soil probiotic secretes polysaccharides that enhance soil aggregation, promoting better water retention, aeration, and microbial diversity, creating optimal conditions for plant growth.

Stress Tolerance (Drought & Heavy Metal Detoxification)
Bacillus mucilaginosus enhances plant resilience to drought stress by improving water retention and root development. It also helps detoxify heavy metals in contaminated soils by binding and transforming toxic elements, reducing their uptake by plants and promoting healthier growth in challenging environments.

Plant Growth Promotion
This plant growth-promoting rhizobacteria (PGPR) naturally stimulates plant growth by producing growth hormones (IAA, gibberellins), leading to stronger roots, faster development, and higher crop productivity.

Eco-Friendly and Sustainable
By enhancing nutrient cycling, B. mucilaginosus reduces reliance on chemical fertilizers, supporting sustainable and organic farming.
