Q: What is Bacillus megaterium and how does it support crop growth?

A: Bacillus megaterium is a naturally occurring, high-performance phosphate-solubilizing bacterium (PSB) and plant growth-promoting rhizobacterium (PGPR). It improves soil fertility, increases nutrient bioavailability, and boosts crop yields by releasing bound phosphorus, enhancing root development, and promoting overall plant vigor. As a trusted biofertilizer and soil probiotic, it reduces the need for chemical fertilizers, supporting sustainable and regenerative farming practices. Applied Biotech Industries offers bulk supplies to commercial agricultural operations.

We serve large-scale farms, agricultural distributors, fertilizer companies, and agricultural businesses looking to integrate beneficial microbes into their soil health programs.

Q: Does Applied Biotech Industries manufacture Bacillus megaterium?

A: Yes. Applied Biotech Industries produces Bacillus megaterium using precision-controlled fermentation technology. Our process ensures consistent microbial counts, optimal shelf-life stability, and superior viability, providing a reliable microbial inoculant solution for sustainable agriculture.

Q: In what form is Bacillus megaterium available, and how is it applied?

A: Bacillus megaterium is available as a highly concentrated dry powder with 100 billion CFU per gram, ensuring maximum viability and effectiveness. While supplied as powder, many customers formulate it into liquid biofertilizers, biostimulants, and microbial soil amendments. It’s versatile for use in fertigation, drip irrigation, compost enrichment, and seed treatments, accommodating a variety of farming methods and crop systems.

Q: Is Bacillus megaterium a genetically modified organism (GMO)?

A: No. Bacillus megaterium is a naturally occurring, non-GMO soil bacterium. We cultivate this strain without genetic engineering and adhere to strict quality controls, ensuring it meets the requirements of organic and sustainable agriculture.

Q: Can Bacillus megaterium be used in certified organic farming?

A: Yes. Bacillus megaterium is frequently used in organic agriculture as a natural soil probiotic and biofertilizer. It enhances nutrient uptake, promotes microbial biodiversity, and supports plant health without synthetic chemicals. However, always confirm compliance with your organic certification body.

Q: How does Bacillus megaterium improve soil fertility?

A: Bacillus megaterium boosts soil fertility through multiple beneficial actions:

• Phosphate solubilization: Converts bound phosphorus into plant-accessible forms.
• Nutrient cycling: Enhances nitrogen and micronutrient availability.
• Root development: Stimulates stronger, deeper roots for better nutrient and water absorption.
• Organic matter breakdown: Accelerates decomposition, recycling nutrients back into the soil.
• Soil microbiome support: Promotes beneficial microbial communities, improving long-term soil health.

Q: Can Bacillus megaterium be mixed and applied with fertilizers?

A: Yes. Bacillus megaterium is compatible with liquid and granular fertilizers. When tank-mixing, always fully dilute fertilizers in water first, then introduce Bacillus megaterium. Avoid mixing it directly with pesticides, fungicides, or bactericides, as these may harm microbial viability. Ensure continuous agitation during application for even distribution.

Q: Which crops benefit the most from Bacillus megaterium applications?

A: Bacillus megaterium effectively supports a wide range of crops, including:

• Row crops (corn, wheat, rice, barley): Improves phosphorus availability and root strength.
• Fruits and vegetables (tomatoes, citrus, strawberries): Enhances nutrient uptake and resistance to stress.
• Legumes and oilseeds (soybeans, peanuts, sunflower): Increases nitrogen efficiency and plant vigor.
• Leafy greens (lettuce, spinach, kale): Boosts micronutrient absorption and leaf quality.‍
• Specialty crops (coffee, cocoa, tobacco): Promotes robust root systems and rhizosphere health.

Q: How is Bacillus megaterium applied in agricultural settings?

A: Bacillus megaterium is versatile, compatible with several agricultural application methods:

• Soil drench: Delivers microbes directly into the root zone.
• Drip irrigation: Provides targeted, efficient microbial inoculation.
• Seed treatment: Ensures early colonization and improves seedling vigor.
• Compost and organic amendments: Accelerates organic matter decomposition and nutrient cycling.

Q: Is Bacillus megaterium safe for the environment?

A: Absolutely. Bacillus megaterium is a naturally occurring, eco-friendly agricultural microbe. It promotes sustainable farming by reducing dependency on chemical fertilizers, enhancing soil biodiversity, and supporting healthy crop systems without environmental harm.
