The Soil Sponge: A Cradle of Life

In the face of an escalating climate crisis that is daily headline news,  it is obvious humanity stands at a crossroads looking at the destruction we have caused.   Perhaps, at that crossroads, we should start to understand that the micro is the same as the macro.   For me, I am more and more convinced the land beneath our feet is a soilution.

I personally feel we are going down a dark path in human history and we need to step back and consider how nature works and how we can mimic her for restoration.   And, I beleive the answer is in water and microbes.

“Although the surface of our planet is two-thirds water, we call it the Earth. We say we are earthlings, not waterlings. Our blood is closer to seawater than our bones to soil, but that’s no matter. The sea is the cradle we all rocked out of, but it’s to dust that we go. From the time that water invented us, we began to seek out dirt. The further we separate ourselves from the dirt, the further we separate ourselves from ourselves. Alienation is a disease of the unsoiled.”

― Tom Robbins, Another Roadside Attraction

Let’s admit that the traditional approach to land management (intensive agriculture, deforestation, and unsustainable practices) has led to soil degradation and exacerbated climate change.   We have destroyed the micro-life.   We have harmed Nature.  However, a new paradigm is emerging, one that recognizes the soil as a vital ecosystem and harnesses its natural power to mitigate any climate change and restore environmental balance.    We touched on this topic in Dr. Elaine Ingham’s Soil Food Web course but I discovered more when I studied with Didi Pershouse and her s teaching on the Soil Sponge.

Didi, with  Australian microbiologist and climatologist, Walter Jehne are teachers of the Soil Sponge concept and how this affects our water cycles.     In my opinion, this is ONE LARGE transformative shift in our understanding of nature and offers a promising pathway towards a sustainable future.

Reconnecting with the Soil Sponge

What is the soil sponge?   When I asked Wikipedia it added the word carbon: “Soil carbon sponge is porous, well-aggregated soil in good health, better able to absorb and retain water”

Beneath our feet lies a world teeming with life – the soil sponge. This is an intricate ecosystem of microorganisms, including bacteria, fungi, and protozoa.   These little guys plays a pivotal role in nutrient cycling, water retention, and carbon sequestration. Healthy soil, rich in organic matter and diverse microbial life, acts as a carbon sink, storing carbon that would otherwise be released into the atmosphere as CO2.

The earth is complex and interconnected living organism. The soil beneath our feet as its vital organs. Just as our bodies rely on a delicate balance of microorganisms to function properly, so does the planet’s health depend on the thriving community of microbes that reside within the soil.  Just as the organs of the human body rely on other organs, the same applies in the soils.  We can not separate things.  It is all connected.

These tiny and often invisible creatures play a pivotal role in maintaining the carbon and nitrogen cycles. They act as nature’s recyclers, breaking down organic matter and transforming it into nutrients that plants can use to grow.   It is connected.   Plants, in turn, are the soil’s protectors, forming a verdant canopy that shields the earth from the sun’s hot rays and the relentless erosion of wind and water. Their roots, like tiny anchors, bind the soil particles together, preventing it from being swept away by the elements.

Through a process called transpiration, plants release water vapor into the atmosphere, creating a cooling effect that helps regulate the planet’s temperature. This water vapor eventually condenses into clouds, which then release rain, replenishing the soil’s moisture reserves and supporting the growth of new life.

But the role of microbes extends beyond the soil. High in the expanse of the atmosphere, reside invisible droplets of water known as atmospheric bacteria. These tiny droplets, acting like miniature sponges, absorb and hold water vapor, contributing to cloud formation and precipitation. In essence, these atmospheric bacteria are nature’s cloud seeding agents, playing a crucial role in regulating the Earth’s water cycle. They help ensure that the planet receives the life-sustaining rainfall it needs to support its diverse ecosystems.

As I deepen an understanding about the Soil Sponge, it becomes more and more obvious that a paradigm shift in our relationship with land and microbes is required.   We need too transition from exploitative practices that degrade soil health to regenerative strategies that restore and enhance soil functionality. This approach embraces the soil sponge as a key ally in the fight against climate change.

Microbes: The Heroes of Carbon Sequestration?

Microbial life within the soil sponge plays a critical role in carbon sequestration. Through a process known as decomposition, microorganisms break down organic matter, releasing nutrients essential for plant growth and converting carbon into stable forms that remain stored in the soil. This process not only reduces greenhouse gas emissions but also improves soil fertility and enhances plant productivity.

The Soil Sponge approach recognizes the symbiotic relationship between soil, plants, and microbes. By promoting healthy soil practices, we foster a thriving microbial community that effectively sequesters carbon and contributes to climate mitigation.

This represents a fundamental shift in our understanding of nature and our role within it. It moves away from the linear, extractive mindset that has dominated agriculture and land management for centuries. Instead, it embraces a regenerative approach that mimics natural processes and promotes long-term sustainability.

Regenerative land management practices, such as  applying and using microbe rich composts, reducing tillage, increasing organic matter inputs, and adopting diverse cover crops, work in harmony with the soil sponge, enhancing its ability to store carbon, regulate water cycles, and support healthy plant growth. These practices not only mitigate climate change but also improve soil health, enhance biodiversity, and increase food production.

The Soil Sponge approach offers a beacon of hope in the face of climate change. It is a observation to the interconnectedness of nature and the profound impact of soil health on the planet’s well-being.

As individuals, we can play a role in this paradigm shift by supporting regenerative agriculture, advocating for sustainable land management practices, and making conscious choices that promote soil health. By embracing the soil sponge as an ally, we can help Nature mitigate climate change, restore ecosystems, and secure a sustainable future for generations to come.    She has already figured it out.
