What is Compost Tea?
Compost Tea is a brewed, living solution that reintroduces beneficial aerobic micro-organisms to the soil — restoring the balanced biology that healthy plants depend on.
Reintroducing aerobic life to the soil
Aerobic organisms are beneficial, oxygen-loving microbes that thrive in well-structured soil where air can circulate. When soil becomes compacted or depleted, those populations crash and the soil turns anaerobic — leading to poor plant health, disease susceptibility and nutrient lock-up.
Compost Tea provides a concentrated source of these beneficial aerobic organisms, so they can re-colonise the soil and get the biology working again.
Compost Tea + DMO = balanced biology
Two halves of the same picture — the oxygen zones and the low-oxygen zones.
Compost Tea — aerobic
Reintroduces oxygen-loving organisms that work where air circulates through the soil’s pore spaces.
Diverse Microorganisms (DMO) — anaerobic
Introduces organisms that thrive in low-oxygen pockets, balancing the other half of the soil profile.
Used together, they address both the oxygenated and low-oxygen zones of the soil — ensuring organic matter breaks down completely and nutrients cycle properly.
The succession scale
Nature’s pathway from degraded ground to living soil.
Where soil gets stuck
Ploughing destroys fungal networks, chemical fertilisers suppress beneficial microbes, and monoculture reduces diversity — leaving soil stuck at the bacterial “pioneer” stage.
The natural progression
Bacteria break down fresh matter and feed fungi, which support protozoa and nematodes, which nourish earthworms — each level relying on the one before it.
How we speed it up
By introducing the right organisms at the right time — Compost Tea and DMO — we move soil up the succession scale faster than natural recovery alone.
Brewing & applying it
Application is straightforward, but it pays to understand it: proper brewing and timing keep the organisms viable so they colonise the soil effectively. The full method is covered in the AfrEcoSoil guides.
