Why URB Optimizes Root Development

Problem

Weak Roots

Solution

Aerobic conditions for root development (better soil structure)

• Bacterial micro-aggregate formation

• Fungal macro-aggregate formation

• OM replenishment

Solution

Better nutrient cycling

• Phosphate Solubilization -- Often phosphate is present in a bound form unavailable to plants. URB's microbial formulation solubilizes the bound phosphate and makes it available to the plant in a usable form. Phosphate is involved in photosynthesis, respiration, energy storage and transfer, cell division, and enlargement. This helps in these ways:

  • Promotes early root formation and growth

  • Vital to seed formation

• Endophytic Bacteria are key for Plant Growth Promoting Hormones (PGPH): Endophytes stimulate radicular development (part of developmental support to overall plant growth) by producing phytohormones such as auxins [50] givverellins (GAs) abscisic acid (ABA), and ethylene (ET), or by modulating the plant's endogenous phytohormone levels.

Solution

Phytosanitation

• This bio-control function is composed predominantly of of Trichoderma strains. They generally grow on the root surface and are effective against root disease in particular, but can also be effective against foliar diseases.

• B. Subtiliis forms biofilms which are dense populations of organisms. These biofilms provide 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.

• Bacillius subtilis subsp. Spizizenii 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

Summary

Healthy root development can be understood as an outcome of two key drivers: oxygen levels of 6ppm + (well-structured substrate) + proper nutrient cycling. The fulcrum of both drivers is the required biology.

Bacteria, through the glues they secrete, create micro-aggregates , which are then formed into macroaggregates by fungi. Because Bacteria and fungi are the only organisms able to decompose materials into organic matter, which enables better soil structure, thus oxygen, water, and nutrient saturation. In short, roots need room to grow (aerobic conditions) and fuel to grow into that room (nutrients consumed). Optimized Roots = Optimized Biology.
