Discover the Soil Food Web in Brown County’s Nature
Have you heard of food chains, where larger creatures consume smaller ones? What about the intricate network beneath our feet known as the soil food web? This complex system is essential for life as we know it.
Most people don't fully appreciate soil. Dr. Elaine Ingham's presentation highlighted that soil might be as crucial as oxygen. Understanding the soil food web can transform how you view your land.

Understanding the Soil Food Web
Dr. Ingham explains how plants manage nutrient cycling in their root zones. By grasping how each plant interacts with its surrounding biology, you gain a new perspective on soil health.
The soil is alive with activity. It's a vibrant community of bacteria, fungi, protozoa, nematodes, microarthropods, and larger creatures. These soil organisms interact in the soil food web, a complex dance of life.
What is 'Dirt'?
Dr. Ingham emphasizes that calling soil 'dirt' is almost disrespectful. The distinction she makes between soil and dirt highlights the importance of soil microbes.
Dirt lacks the vital life found in healthy soils. Soil, with its structure, provides porosity for airflow, giving all that beautiful soil life what it needs. Lifeless 'dirt' harbors diseases, whereas, in normal soil, those diseases don't get a chance to cause harm to growing plants.
The Players in the Soil Food Web
Bacteria and fungi form the base of this intricate web. These decomposers consume organic matter, such as dead leaves and tiny roots. The magic unfolds in the subsequent steps.
Protozoa and nematodes feed on bacteria and fungi. These predators release nutrients in a form that plant roots can absorb. It's a symbiotic relationship that benefits the entire soil ecosystem.
| Organism | Role | What They Eat | What Eats Them |
|---|---|---|---|
| Bacteria | Decomposers, nutrient retention | Organic matter, root exudates | Protozoa, bacterial-feeding nematodes |
| Fungi | Decomposers, nutrient retention, soil particles builders | Organic matter, root exudates | Protozoa, fungal-feeding nematodes, microarthropods |
| Protozoa | Nutrient cyclers | Bacteria, fungi | Predatory nematodes, microarthropods |
| Nematodes (bacterial/fungal feeders) | Nutrient cyclers | Bacteria, fungi | Predatory nematodes, microarthropods |
| Microarthropods | Nutrient cyclers, soil particles builders | Fungi, nematodes, other microarthropods | Larger arthropods, birds, etc. |
| Mycorrhizal fungi | Builds root systems | Root exudates | Protozoa, fungal-feeding nematodes, microarthropods |
Microarthropods also play a vital role. They accelerate decay and create pathways for air and water, essential for plants growing strong.
Nutrient Cycling in the Soil Food Web
Dr. Ingham discussed how plants generate 'exudates'. Exudates nourish microorganisms near the plant roots.
This facilitates predators like nematodes, microarthropods, and protozoa consuming these microorganisms. Consequently, nutrients stored in fungal and bacterial bodies are released, benefiting your plants. It is great for the soil ecosystem.
Without structure and these organisms, water pools and loses oxygen. This can lead to unfavorable conditions for us and impact garden soil substantially.
The Role of Mycorrhizal Fungi
Mycorrhizal fungi connect to plant roots, expanding their reach. This allows plants to access more nutrients and fosters a mutually beneficial relationship.
Soil lacking life becomes compacted, hindering drainage and causing the ground to shift. Proper soil life, especially from cover crops, helps prevent erosion. Even a whole hill can be impacted by erosion.
How Plants Control the System
Plants aren't passive; they actively influence their environment. They release substances called 'exudates' through their roots to nourish nearby microbes.
Dr. Ingham explains in her work that exudates consist mainly of sugars, proteins, and carbohydrates. She likens it to plants baking treats to attract microscopic helpers. These helpers are critical to a good food soil web.
Different bacterial and fungal species target various ingredients plants release. This specificity depends on factors like soil type, location, and plant growth stage. This is key for all organic gardeners to be aware of.
Different species have specific roles, such as mining different nutrients. Dr. Ingham notes that this 'sleep mode' ends when the right exudates become available.
Why We Need 'Local' Microbes
Forest soil differs significantly from farmland soil. Every environment, including your yard, possesses a unique biology. Your plants understand what should be present, releasing specific exudates accordingly.
Using compost from your property is more effective than using generic products. Decomposing organic matter releases nutrients back into the soil, and the right organisms deliver them to plants. These local soil microbes are key.
Compaction: A Threat to the Soil Food Web
Compaction eliminates vital air space. Dr. Ingham emphasizes that it destroys beneficial soil life due to lack of oxygen, not just by hindering root growth. This can create conditions detrimental to garden soil.
Without air, harmful elements thrive, Dr. Ingham explains. This creates a breeding ground for disease and plant damage. Visual cues, even the appearance of tree trunks, can signal the need to assist your soil.
The U.S. Department of Agriculture highlights the link between erosion and soil health in their overview on soil health. Degraded soil structure, insufficient life, and water issues affect everything from home gardens to national food production.
The Soil Food Web & Nutrient Availability
Plants require more than just N-P-K (nitrogen, phosphorus, potassium). Fungi and bacteria transform rock minerals and decaying matter into accessible nutrients for plant roots. Without those soil microbes, the minerals are unusable.
Nutrient release also occurs in the ocean, as reported on Wired. It's a universal process not limited to land.
When conducting a soil test, don't focus solely on soluble nutrient results. Nutrients in rocks are still valuable, and we need those bacterial and fungal allies in the food soil web.
How To Improve Soil Health Naturally
Nature has an inherent process for self-nourishment. Plants introduce the right organisms when conditions permit. Plants play a larger role in our systems than commonly believed.
Dr. Ingham mentions that we used to harm soil life. We must maintain a balance of organisms with the necessary functions. She advocates for compost extracts and compost teas to restore diversity and boost populations.
Practical Steps to Restore Your Soil Food Web
A key takeaway from the Soil Food Web discussion is to avoid tilling. Disturbing the ground and the already present organic material doesn't enhance its ability to produce beneficial elements; in fact, it does the opposite. It is critical to not hurt the soil ecosystem.
Adding homemade compost to your garden is simple. Dr. Ingham, in an interview with the Joe Gardener podcast, advises using locally sourced materials and retaining leaves. Materials from your vicinity likely contain biology beneficial to your garden. That is important for organic gardeners.
FAQs about soil food web
What is the soil food web?
The soil food web comprises organisms residing in the soil. These include bacteria, fungi, protozoa, nematodes, microarthropods, and larger creatures.
They collaborate to decompose and cycle organic matter, including plants. They can even adjust biology in their systems.
How to build soil food web?
Prevent soil compaction. Retain native plants on the soil surface for proper nutrient cycling. Compost is another effective solution and is critical to soil health.
What is a soil food web with trophic levels?
Consider each stage in this 'chain'. Plants and compost nourish organisms.
Then, other soil biology consumes them. These soil inhabitants also have predators, mirroring larger food webs. All thanks to plant roots.
Is soil a producer or consumer?
Soil contains organisms with specific roles, such as fungi and bacteria with mycorrhizal functions. It can even have cover crops that contribute as producers.
Higher-level organisms act as consumers. Protecting these systems by providing food, porosity, and allowing plants to manage their environment is our responsibility as organic gardeners.
Conclusion
Modern agriculture frequently prioritizes immediate yields over sustained soil health. However, neglecting the entire system leads to eventual degradation.
As inhabitants of Earth, we tend to adhere to one method, forgetting the purpose of each element in our ecosystem. Grasping the intricacies of the soil food web enables us to embrace sustainable agriculture that benefits us in the long run, a seemingly daunting task that's surprisingly simple. We need to get our soil microbes in order.
