ACF-SR delivers a broad spectrum of beneficial soil bacteria, including difficult to stabilize non-sulfur photosynthetic microbes in a blend with a minimum two-year shelf life.
There are three types of microorganisms in AAG’s 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 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 AAG products. 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
ACF-SR has unique bioformulas designed to improve the foliar and
rhizosphere processes, which increase the capture of light and
the conversion of the sugars to available plant energy. These
bio formulas improve photosynthesis and uptake of carbon
and mineral nutrients within the rhizosphere, resulting in
reduction of disease pressure that allows the plants to focus
their energy on growth, reproduction, and yield, with fewer
chemical inputs. The increased light absorption results in better
conversion of CO2 and organic carbon into essential
carbohydrates, improving the plant’s usage of energy in both foliar
and rhizosphere, resulting in healthier, more vigorous growth.
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
ACF-SR actually makes amendments to the soil structure,
allowing water to go deeper. The bacteria in ACF-SR help
the roots grow deeper, while creating more hair roots so they can
absorb water from deeper soil. In general, the plant is healthier and able
to uptake more nutrients as the bacteria help in transforming inorganic
nutrients into organic, water-soluble forms, as well as improve nitrogen
and phosphorous uptake. There are two additional mechanisms responsible
for the enhanced drought resistance. The bacteria form biofilms that are
hygroscopic and will help to retain water, much like super-absorbent polymers,
which, in turn, help reduce evaporation and transpiration, conserving water.
Also, the photosynthetic bacteria generate water.

The rhizosphere is the narrow region of soil around the
root tip where plants encourage the growth of beneficial
bacteria by the secretion of sugars and sloughing off of plant
cells that feed them. Beneficial bacteria grow in the
rhizosphere where they breakdown complex organics and
provide auxins, hormones, and other nutrients that help the plant
grow. Therefore, much of the nutrient cycling and disease suppression occurs in populations in the root zone.
Plants have a limited ability to genetically adapt to rapid environmental changes (heat, drought, toxins, or limited nutrients) and so they may use ACF microbes that do have this capacity to rapidly evolve due to their vastly shorter life cycles. By having the right microbes for the conditions, the plants are healthier. This is similar to humans taking probiotics to improve their health.
Vegetative Strains and Spores
Some bacteria, notably the Bacilli, produce a protective spore in unfavourable growth conditions as a survival mechanism. Spores provide long-term survival during desiccation (for dry products) and protect the organism when formulated in unfavourable liquids. However, these spores require time to germinate (just like a seed) which delays their action during product usage.
While Bacillus spores are very effective at providing some compounds useful to plant growth, nitrogen and carbon fixation. When the spores germinate and become active, they are considered to be in the vegetative or "growing" form.
Many organisms are not capable of producing spores. They are always in the active form where they perform immediately upon application. However, it is much more difficult to maintain these strains in a stable formulation. ACF SR has a unique, stable formulation of vegetative strains with excellent shelf-life.
Plants consume ammonium and nitrate. Ammonium is a positively charged ion and binds to the soil's negatively charged surface. Nitrate is a negatively charged ion and does not bind to the soil, but is dissolved in the soil water.
Approximately half of nitrogen in manure is in the form of ammonium and about half is in the form of organic material. Microbes that consume the organic compounds excrete ammonium. The ammonium may be
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
