Community composition
RhizeBio scored eighteen functional traits. Every one of them is below, grouped the way the report groups them, including the middling results. A brand that hides its unremarkable numbers has not earned to be believed about its good ones.
Oxygen availability
Low-oxygen function
89%Very high
The biology keeps working in the wet, packed pockets where most soil life stalls.
High-oxygen function
84%Very high
Fully aerobic and mature — the sign of compost that was finished properly, not rushed.
Anoxic environment
60%Medium
Function continues even where oxygen runs out, deep in a compacted bed.
Nitrogen cycling
Denitrification
89%Very high
Completes the nitrogen cycle instead of letting it stall — a sign of a mature, balanced community.
Organic nitrogen breakdown
73%Medium
Feeds steadily all season instead of spiking and crashing like a synthetic.
Nitrogen fixation
69%High
Pulls nitrogen out of thin air and hands it to your plants.
Methanogenesis
61%Medium
A normal part of a mixed community with both aerobic and anaerobic pockets.
Nitrification
41%Medium
Converts ammonium to nitrate, the form roots absorb most readily.
Carbon cycling
Carbon fixation
89%High
Builds stable organic matter, so the ground holds together and holds water for years, not weeks.
Organic carbon breakdown
59%Medium
Turns raw organic matter into food for the soil at a measured pace.
Nutrient cycling
Iron acquisition
85%Very high
Unlocks iron the plant can actually take up — what keeps leaves deep green instead of pale.
Phosphorus mobilization
64%High
Frees up locked phosphorus — the fuel behind big blooms and heavy fruit set.
Potassium solubilization
61%High
Makes potassium available, which is what stiffens stems and firms up fruit.
Calcium transport
61%High
Moves calcium where it is needed — the mineral behind blossom-end rot when it is missing.
Sulfur reduction
57%Medium
Part of the sulfur cycle that keeps proteins and enzymes building in the plant.
Sulfur oxidation
54%Medium
Converts sulfur into the sulfate form roots can absorb.
Plant growth promoting
Plant stress adaptation
83%High
Helps plants ride out a Carolina heat wave and a dry spell without checking out.
Nodulating bacteria
58%Medium
The partners legumes need — beans, peas and clover form root nodules with these.
How to read these
A score is the share of the sequenced community carrying genes for that function — not a measure of how well your garden will do. High nitrogen numbers mean the biology to cycle nitrogen is present. Nitrification at 41% is the weakest trait in the panel, and we publish it at the same size as the strong ones.
Named organisms
Streptomyces
10.22%
The bodyguard
The single most abundant organism in the sample. Produces natural antibiotic compounds that suppress soil-borne disease.
Mycobacterium
4.23%
The recycler
A widespread environmental genus that breaks down tough, waxy organic compounds other organisms leave behind.
Pseudomonas
2.32%
The scout
A plant-growth-promoting bacterium that frees locked phosphorus and drives dense, fibrous rooting.
Sphaerobacter
2.06%
The heat-lover
A thermophile — its presence is a fingerprint of a pile that genuinely ran hot.
Nitrospira
1.49%
The nitrogen finisher
Completes nitrification, turning ammonium all the way through to the nitrate roots take up.
Bradyrhizobium & Mesorhizobium
1.93%
The nitrogen crew
The root-nodule partners behind the nitrogen-fixation score. Combined 0.97% + 0.96%.
Bacillus
0.45%
The trainer
Primes the plant's own immune response — systemic acquired resistance — before trouble arrives.
Oxygen niches
6.6%
Facultative anaerobic
2.4%
Microaerophilic
0.8%
Obligate anaerobic
A mature compost carries both aerobic and anaerobic micro-sites, so a wide range of biological processes can run at the same time.
