Soil Autopoiesis:

The Science of Self-Organising Fertility

Whether a strand of DNA, or a triplet of badger pups (don't ask me why I chose badgers:), we too easily overlook the astounding miracles our planet has developed to self-perpetuate. That being its dynamic nature to optimise for sustained metabolic function as a fundamental, universal biological phenomenon. The word I like to coin is 'autopoesis' (coming from the Greek: auto- meaning “self” and poiesis meaning “creation).

Self-replication, or the capacity to be self replicated (the difference is tremendous) is a core property of living systems and underpins evolution, heredity, and all biological persistence.. This is the common denominator across all scales and is vitally important when we wish to understand how soil functions.

When you pick up a handful of woodland soil, you’re holding a vast, living system that builds, reshapes, and maintains itself through countless interactions among organisms, minerals, roots, and the invisible flows of energy from the sun. This capacity for dynamic self-organisation and renewal is what scientists call soil autopoiesis. In soil science, autopoiesis refers to soil’s ability to self-organize, self-maintain, and regenerate its functional and structural components through the continuous activity and feedback among its living constituents. This is increasingly recognized in scientific literature as a foundational property of living, fertile soils.

This isn’t abstract. It matters deeply when we turn our attention to soil. What many mistake for inert matter is, in fact, an exquisite expression of life’s self-organising intelligence. Soil, like DNA, builds and rebuilds itself through feedback, interaction, and flow—an emergent process scientists are beginning to describe as soil autopoiesis.

What Is Autopoiesis?

The term autopoiesis was first conceived in biology, referring to the ability of living cells and organisms to produce, repair, and maintain all the structures necessary for their survival, preserving both their identity and function over time. In essence, an autopoietic system is one that continually regenerates and maintains itself, distinguishing it from its surrounding environment.

When applied to soils, autopoiesis describes the soil ecosystem’s capacity to self-organize, self-maintain, and continually recreate both its structure and its functions. This is not just an abstract idea: the microbes, fungi, roots, and fauna that animate soil are constantly engaged in a network of feedbacks—breaking down organic matter, cycling nutrients, forming aggregates, and building the microhabitats essential for life.

Soil as a Living, Coupled System

Crucially, soil autopoiesis is not a closed loop. It’s a self-renewing process fundamentally powered and regulated by the soil’s environment.

- Sunlight is captured by plants through photosynthesis, producing sugars and organic compounds that become the primary energy source for the soil food web—fueling bacteria, fungi, and larger soil animals.

- Rainfall brings water, dissolved minerals, and fluctuating chemistry, all of which affect microbial activity and the mobility of nutrients.

- Animals—from earthworms to grazers and small mammals—contribute by mixing soils, introducing organic residues (such as dung and leaf litter), creating micro-channels, and periodically stressing plants, which increases the flow of exudates or root “leaks” into soil.

Through these linkages, soil autopoiesis emerges as a dance between the system’s internal complexity and the continual pulse of external forces.

Achieving Critical Mass: Why Soil Life Must Multiply

A foundational requirement for soil autopoiesis is a critical mass of soil biodiversity—a threshold level of living organisms and interdependent functions, below which the self-organizing dynamics may fail to manifest. Soil health isn’t sustained by a few dominant species, but by a bustling community that includes bacteria, archaea, fungi, protists, nematodes, microarthropods, and macrofauna.

This diversity is pivotal because:

- Each organism or group carries unique functional genes—nutrient cycling, aggregate formation, disease suppression, or plant signaling.

- Redundant pathways ensure resilience: if environmental change or disturbance knocks out some members, others can take their place.

- Highly interactive microbial networks generate a robust web of feedback loops, shaping their own microenvironments—regulating pH, oxygen, organic acid levels, and more.

Without sufficient diversity and microbial abundance, soil cannot “boot up” the full spectrum of processes needed for fertile, self-sustaining life. This critical mass isn’t just numbers; it’s the densely woven pattern of collaboration, competition, and mutual transformation.

Photosynthesis: The Engine of Soil Autonomy

The sun, harvested through photosynthesis, is the ultimate driver of soil autopoiesis. Plants channel tremendous amounts of energy belowground in the form of carbon exudates—simple sugars, organic acids, amino acids, and more—which:

- Feed and select for beneficial soil microbes;

- Accelerate the breakdown and transformation of organic and mineral matter;

- Stimulate the formation of humus and stable soil aggregates;

- Fuel the mycorrhizal fungi that extend plant roots and tap into distant water and nutrients.

A healthy plant-microbe partnership can transform otherwise inert “dirt” into living soil. As photosynthetic activity increases, so does the diversity, abundance, and function of the soil food web. The more energy flows in, the more autonomy the system achieves—up to a plateau where nutrient, moisture, and habitat limitations begin to constrain growth.

Thus, autonomous, resilient soil fertility is ultimately mediated by a feedback loop: plants feed the soil, which in turn supports plant growth, further enhancing the flow of solar energy into the earth.

The Environmental Web: Water, Weather, and Animal Life

While sunlight provides the energy, it’s not the sole determinant of soil autopoiesis. Water regime—the pattern of rains, droughts, and microclimates—greatly influences which soil organisms thrive, when nutrients cycle, and how quickly decomposers work. Changes in rainfall patterns can shift the very balance of ecosystem respiration and carbon cycling in soils, sometimes strengthening and sometimes weakening the soil’s ability to sustain itself.

Animal activity, too, is indispensable. From surface grazers to deep-burrowing mammals, animals stir soil, shape its structure, introduce organic material, cycle nutrients, and even affect the carbon balance through respiration and waste. Ecological studies show that animal biodiversity is directly linked to the stability and productivity of terrestrial carbon cycles.

When Soil Loses Its Autopoiesis

Soil autopoiesis is not guaranteed. Intensive tillage, heavy chemical inputs, monocultures, sealing soils under asphalt, or chronic nutrient extraction can drive biodiversity below critical mass, disrupt microbial feedbacks, and sever the vital energy flows from the plant-soil network. Under these circumstances, soil may become inert, unresponsive, and unable to regenerate on its own—needing continual outside intervention to remain productive.

Toward Regenerative Soil Systems

Understanding soil autopoiesis calls for a shift from seeing soil as a passive medium to a living, self-organizing partner. Approaches that nurture critical microbial diversity, preserve organic carbon inputs, and maintain the solar-powered plant-soil feedback loop can restore and sustain soil fertility for generations. Techniques such as cover cropping, organic amendments, reduced tillage, diverse crop rotations, and the reintroduction of grazing animals all help tip the balance toward a fully functional, autopoietic soil ecosystem.

Conclusion

In sum, soil autopoiesis describes a profound truth: soil is alive, powered by a critical mass of interacting organisms, and animated by the perpetual flow of sunlight, water, and biological activity from above and around. It is not a siloed system—it is an open, dynamic, and self-organizing web whose autonomy depends on ongoing energy and material inputs. Supporting this delicate balance is the foundation for regenerative agriculture, resilient landscapes, and a sustainable future for food and ecosystems everywhere.
