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.
