ACF-SR delivers a broad spectrum of function-focused, beneficial soil bacteria, including difficult to stabilize, non-sulfur photosynthetic species.There are 3 types of microorganisms in our microbial blends:
- Photosynthetic bacteria supply energy from light, fix nitrogen and carbon, degrade toxic chemicals, and supply organic carbon to plants for growth. These bacteria improve the efficiency and effectiveness of CO2 fixation
- Vegetative strains improve the soil by breaking down residual toxic chemicals. They also break down complex organics to provide nutrients to plants
- Bacillus spores are the most common microbial additives in any biological product. They are known to produce auxins, hormones, and other substances to promote plant vigor. They also breakdown complex organics to produce forms readily available to plants
Function Focused Bacteria
- Adding ACF-SR is really adding functions
- These functions supply extra nutrients in BIOAVAILABLE FORM
- The functions include growth hormones and digestion of complex organics
- The entire biomass benefits from the functions provided by ACF-SR
Rather than think about what species are supplied by ACF-SR, instead, realize that ACF-SR is providing the full spectrum of Plant Growth Promoting Functions. With these functions supplied by ACF-SR, the growth and diversity and health of the bio-flora is optimized.
To ensure that ACF-SR provides the full spectrum of needed functions, we grow individual bacteria species on special nutrients and under special conditions, to ensure that Plant Growth Promoting (PGP) functions are present, without genetic engineering.
Below is a fingerprint of all the DIRECT functions built into ACF-SR:
ACF-SR and Other “Biological” Products
Using our innovative growth/brewing procedures, the full range of PGP traits are not only assured in all of our products, but a super high concentration and dosage can be applied at an affordable cost.
Our multi-species formulas provide full-spectrum performance, significantly better than single-species products.
Other soil amendments, such as compost tea, digestate, or manure addition, simply add bacteria, but not necessarily the right bacteria needed for the specific PGP traits and performance.
Whenever bacteria or fungi are randomly grown in a rich nutrient mix (such as compost tea), the fastest-growing microbes dominate, and those are not likely to possess the required functions or traits.
Survival of the fastest: In order to survive in a complex mixed culture, bacteria must reproduce as quickly as possible. Slow growing bacteria are lost in the population compared to fast growing bacteria as depicted below:
Fungi & Bacteria
When does Fungi Create Enzymes?
- Facilitating Resource Acquisition: Enhanced root structure allows for superior nutrient acquisition
- Nitrogen Fixation: Bacterial conversion of N2 into bioavailable nitrogen
- Phosphate Solubilization: Bacterial conversion of non-available Phosphate into reactive (bioavailable) PO4
- Sequestering Iron: Iron is required at high levels but is not very soluble. Bacteria produce siderophores, which encapsulate iron and make it available to plants
- Modulating Phytohormone Levels: Produced by bacteria under stress (heat, drought) to aid the plant’s survival
- Cytokinins and Gibberellins: These are plant growth stimulating and modulating hormones that are directly produced by bacteria
- Indoleacetic Acid: A plant growth regulating hormone, perhaps the most important one
- Ethylene Production: Another plant growth hormone
Vegetative Strains and Spores
- Used by plants immediately
- Converted to ammonia when the pH is higher than 7.8 and lost in the air
- Converted to nitrate
- Used by microbes for synthesis of amino acids and proteins and immobilized
Treating manure with microbes:
- Converts organic nitrogen to ammonia and inorganic nitrogen compounds by ammonification
- Converts inorganic nitrogen into cell protein
The cell protein of the bacteria-containing nitrogen is released slowly through mineralization. The benefits include
- Microorganisms store nutrients, which allow the nutrients to remain available to the plants over a much longer period of time
- Reduce loss of nutrient through run off by allowing microbes to attach to soil and organic matter
- Increase crop yields
- Lower fertilizer costs by improving performance of fertilizer
- Reduces potential for pollution by storing in non-soluble forms of nitrogen available to plants, but not as likely to run off during periods of heavy rain
“Bacillus and are among the most powerful phosphate solubilizers.”
– Biotechnology Advances 17 (1999) 319–339
By liberating NH3 from organic compounds in the soil, Bacillus allows nitrifying bacteria to convert NH3 to NO3. This is what MUST occur for nitrifiers to help in solubilization.
The synergy between the various microbes in our formulas allows for optimal P solubilization, which is also extremely important in alkaline soils.
