In this article we are unveiling the intriguing link between Soil Microbes and human gut health by the role beneficial soil microbes play in plant nutrient delivery.

Today, studies show that humans are around 90% deficient of beneficial gut bacteria. This is due to an increase in artificial environments, chemical pollutants, our obsession with over-sanitising, and not spending enough time in nature, or eating natural food.

Soil microbes play a crucial role in maintaining the health of our gut. These beneficial microorganisms have a symbiotic relationship with plants by helping them absorb nutrition from the soil.

When we consume nutrient-dense foods, we indirectly consume these beneficial microorganisms along with the essential nutrients that they have transported into the plant.

Our Gut Houses Trillions of Microorganisms

The connection between soil microbes and gut health lies in the fact that our gut is home to trillions of bacteria that make up our microbiome. This microbiome plays a vital role in various aspects of our health, including digestion, immune function, and even mental well-being.


Consuming nutrient-dense foods grown in soil rich with diverse microbial communities positively effects our health



The presence of beneficial microbes, in the microbiome, enhances nutrient absorption, promotes a healthy balance of bacteria, and supports overall digestive function.

Research suggests that individuals who consume diets rich in fruits, vegetables, whole grains, and other plant-based foods tend to have a diverse and healthy gut microbiome. This diversity is associated with better overall immunity and health outcomes.

Parallels of the Human Gut and the Soil

The human microbiome has many parallels with the behaviours of soil microorganisms and their relationship with plants. In both cases, there is a diversity of microbes and biological activities performing a myriad of different functions.  For example, there are creative microbes, stabilising microbes, and demolishing microbes. This diversity of microbes all function together as a whole, and need each other to perpetuate the cycle of life.

The human body houses microbes in the gut, mouth, nasal passages and other ‘habitats’ both in and on the body.  We have coevolved as ‘superorganisms’ with microbes that perform critical functions and provide essential ‘health services’.

The microbial health of our gut is inextricably linked to the health of the microbes in the soil.  We are at the stage now in our human evolution where we are just beginning to understand what soil microorganisms do.


Soil microorganisms cycle nutrients and water to plants and ultimately to our food and the human organism

The bacteria in the soil is akin to the “stomach” of plants.  Soil microbes have a symbiotic relationship with plant roots, and enable the digestion of nutrients to happen, so that the plants can assimilate nutrients.

The Benefits of Beneficial Microbes in the Soil

Boosting beneficial microbes in the soil has numerous benefits for agricultural, environmental, and human health purposes.

Soil microbes, which include bacteria, fungi, and other microorganisms, play a crucial role in maintaining soil health and fertility.

One of the key benefits of promoting beneficial microbes in the soil is improved nutrient cycling. These microorganisms break down organic matter and release essential nutrients that plants need for growth. This process enhances nutrient availability and uptake by plants, leading to healthier and more productive crops.

Additionally, beneficial soil microbes can help suppress plant diseases. Some microbial species have the ability to inhibit or compete with pathogenic organisms, reducing the risk of crop infections and increasing natural plant immunity.

Why we need Healthy Gut Microorganisms

Microbes in the human body aid digestion and maintain our immune system.  Soil microorganisms digest nutrients and protect plants against pathogens and other threats.  Are you getting the correlation?

For example, plants form symbiotic associations with fungi that colonise their roots and extend the reach of the roots a hundred-fold.  These fungal filaments channel nutrients and water back to the plants cells.  Furthermore, these filaments are also used as communication systems for the plants to warn other plants of threats or pests, ie. immunity.

Interrupting these intricate pathways, through heavy tillage or chemical overuse, inhibits the plants immunity, just as interrupting the human gut microbiome, by way of eg. chemical consumption, can deplete the human immune system.

Soil and Gut Health Solutions

Vital microbes, in the human gut, are destroyed through the overuse of antibiotics, chlorine, and chemicals used in farming and processed foods.  We have also devastated the microbiota in the soil through the overuse of chemical fertilisers, fungicides, herbicides, pesticides and heavy tillage.

Reintroducing beneficial soil bacteria to depleted soil is akin to eating naturally cultured and grown foods to restore the gut microbiome

How To Repair The Damage

Repairing the soil can be done through regenerative agriculture and natural farming, using natural soil care practices, and organic inputs like Biological Fertilisers.  These are practices that can be effectively applied to both small or large-scale agricultural systems.

The best way to restore the human gut health is to eat a diversity of fresh foods, particularly leafy greens, that have been grown and picked fresh, from natural ‘living’ soil as well as naturally cultured or fermented foods.


It is now believed that autoimmune and other diseases is owed to the disruption between our bodies and the natural microbial soil system that we coevolved with.  Zach Bush MD describes this in detail in the above excellent video.
