Meet Our Microbes

While the idea of microbial inoculants for stimulating crop production is not new, careful and deliberate design of a formulation to contain multiple, naturally occurring phylogenetic groups of organisms with complementary functionalities and noticeable effects from seed to final flush, with little or no need for added chemical fertilizers and pesticides is innovative.

URB Sciences believes the design of the URB product line is better than any of its competitors since it takes a holistic, synergistic approach to boosting crop yields and decreasing inputs in a sustainable manner. The documented benefits achieved with URB are clearly better than any known competitor.

All liquid formulations are Certified Organic


Our precision engineered microbial formulation is suspended in a triple screened 12% humic acid carrier, stabilized at a balanced pH of 7.0, which allows it to effectively work in all mediums and growing systems.These humates act as a carbon food source for the microbial formulation, are high in organic matter and contain micronutrients, such as calcium, magnesium, zinc and manganese.

  • Bacillus subtilis- or B. sub, is a key beneficial plant bacteria. B. subtilis plays a role in replenishing soil nutrients through both the carbon cycle and the nitrogen cycle. To aid thecarbon cycle B. subtilis degrades thatch, pectin, cellulose and other organic materials. B. subtilis forms biofilms which are dense populations of organisms. These biofilms provides the plants with preventive colonization, sometimes called competitive inhibition. While beyond the scope of this post, preventative colonization essentially prohibits other microorganisms from forming colonies around the plant roots.

  • Bacillus megaterium- Another key beneficial plant bacteria is Bacillus megaterium. In addition to some of the benefits conferred by B. subtilis, B. megaterium is known to be a phosphate solubilizing bacteria (PSB). PSBs have several important benefits:
    -They make phosphorus more available to the plant
    -Reduce the need for traditional fertilizer applications
    -Increases uptake of water. Increases disease and drought resistance.
    -Reduce Environmental problems downstream
    -Promote sustainable growing practices.

  • Bacillus licheniformis- is a spore-forming soil organism that contributes to nutrient cycling and has antifungal activity. There is current research on B. licheniformis (strain SB3086) and its effects as a microbial fungicide.t is a gram-positive, mesophilic bacterium. It can exist in a dormant spore form to resist harsh environments, or in a vegetative state when conditions are good. High capacity of secretion of the alkaline serine protease has made B. licheniformis one of the most important bacteria in industrial enzyme production.

  • Bacillius subtilis subsp. spiziizeni - Prevents & controls Root Rot. Plant growth promoting rhizobacterium shown to synthesize antifungal peptides. This ability has led to the use of B. subtilis in biocontrol. Also proven to increase crop yields, although it has not been shown whether this is because it enhances plant growth, or inhibits disease growth. They are also capable at growing at pH values, temperatures, and salt concentrations where few other organisms can survive.

  • Bacillus pumilus- participates in a wide range of symbiotic relationships. B. pumilus can function as a plant growth promoting rhizobacteria within the rhizosphere. Additionally, B. pumilus is thought to function as a plant growth promoting endophyte.

  • Trichoderma harzianum strain T-22- Is one of the most effective strains of this fungus It is able to colonize the roots of most plant species across a wide range of soil types. This fungus is used as a biocontrol agent during crop production, and for the improvement of the rooting and acclimatization phases in plants. Using Trichoderma harzianum strain T-22 during the rooting phase results in greater shoot lengths, as well as increased numbers of leaves, roots, and stem diameters. T-22 promoted plant growth by both indirect and direct mechanisms, promotes enhanced root growth, root development, and root function by means of hormonal and biochemical signals. Highly effective on seed germination when doing undiluted URB soaks.
