Paenibacillus Polymyxa

Improve your soil health and plant growth with Paenibacillus polymyxa

Paenibacillus polymyxa (Formerly called Bacillus polymyxa) is a Gram-positive, spore-forming, rod-shaped bacterium that has many beneficial properties for gardening and agriculture. This inoculant contains soil probiotics can promote crop growth by increasing root development, improving nutrient uptake, and enhancing drought tolerance. Moreover, they act as organic soil soluble fertilizers to degrade pollutants in grow media, like polycyclic aromatic hydrocarbons and heavy metals. If you want to increase your crop yields, consider using inoculant fertilizer, Novobac is a leading fermentation factory that produces high-quality inoculants for your gardening needs.

Antagonistic Activity

antagonistic activity of P. polymyxa

P. Bacillus polymyxa soil probiotics inhibits some pathogenic fungal diseases:

A. Phytophthora capsici

B. Fusarium oxysporum

C. Colletotrichum truncatum

D. Botrytis cinerea

E. Sclerotinia sclerotiorum

F. Rhizoctonia solani

Mode of Action

Nitrogen fixation: Convert atmospheric nitrogen into a form that is usable by crops. This helps to improve maintaining fertility and promoting plant growth.

Phosphate solubilization: Producing enzymes that can solubilize insoluble phosphates in farmland, making them available for uptake.

Biocontrol agent: Secrete antibiotics and secondary metabolites, including polymyxins and bacitracin, that have biocontrol activity against pathogens like Fusarium and Phytophthora species.

Rhizosphere colonization: Colonize the root zone and form symbiotic relationships with the roots.

Plant growth-promoting: Produce a range substances, including indole acetic acid (IAA), gibberellins, and cytokinins, that can stimulate nutrient uptake, and enhancing drought tolerance.

Organic soil conditioner: Degrade various polycyclic aromatic hydrocarbons pollutants. Incorporating inoculants rich in beneficial bacteria and other soil probiotics into your gardening routine can improve plant growth without the environmental damage caused by chemical fertilizers.

Benefit

Increase the availability of nutrients including nitrogen and phosphorus.
Improve structure, fertility, fluctuation and porosity as soluble fertilizer.
Increase root expansion through producing hormones like cytokinins, auxins, ethylene and gibberellins.
Decrease the activity of pathogenic fungis by producing antibiotics and promoting immunity of rhizosphere.
Nitrogen fixing ability that can converted atmospheric nitrogen into a form that is usable by plant, such as nitrates (NO3-) or ammonium (NH4+).
Improve water retention and nutrient uptake.

Application Rate

Preparation: Mix the microbe feeding fertilizer powder can be mixed with water to form a suspension, which can then be applied to the grow media or foliage.

Dosage: Recommended dosage is 2-3 kgs per hectare, can be soil drench or watering irrigation.

Application frequency: Can be applied at planting, during crop development, or at any other stage. It is also possible to reapply the soil probiotics at regular intervals at 30 days.

Optimal growth conditions: optimally grows at temperatures between 20-40°C, and in an alkaline to neutral pH environment.

For a healthy microbial ecosystem and to maintain biodiversity, it is important to use a diverse range of bacteria and fungi, including Rhizobia, Mycorrhizal fungi, Trichoderma, Azotobacter and Bacillus Subtilis.

Key factors for successful apply Paenibacillus polymyxa powder

Soil preparation: Free of harmful pathogens and other contaminants before applying it.
Watering: Kept moist but not waterlogged after application to allow it to colonize the soil effectively.
Timing: Applied at any stage of crop development, but it is generally most effective when applied in the early stages of growth when the crop is actively establishing its root system.
Compatible products: It is important to ensure that the soluble fertilizer is compatible with any other inputs, including fertilizers or pest control products.
Product quality: The quality of the bacteria being used is important for maximum efficacy. The product should be fresh and have a high bacterial count to ensure that a sufficient number of bacteria are present in the farmland.
Application method: Mixing with water or applying directly to the grow media, can also affect the efficacy. It is important to follow the instructions provided by the manufacturer to ensure that the product is being used correctly.
