Symbiotic Microorganisms: What Are They and How Are They Used to Improve Crop Quality?

Biologicals

In agriculture, achieving high productivity and profitability often involves a combination of advanced genetics, irrigation systems, and nutrient management. While these tools are important, growers are starting to integrate them with biological solutions. These solutions help support long-term soil health and sustainability.

One solution lies in the use of symbiotic microorganisms. These are natural allies that help plants boost performance, build resilience, and unlock the full potential of your crops.

What are symbiotic microorganisms?

Symbiotic microorganisms are beneficial microbes — such as certain fungi and bacteria — that form mutualistic relationships with plants. These relationships are not just passive. They involve active exchanges of nutrients and signals. These exchanges benefit both plants and microorganisms.

One well-known example in agriculture is mycorrhizal fungi. These fungi form special structures with plant roots. This helps plants exchange nutrients and water. 

In this process, the fungus develops towards the outside of the root through extramatrical mycelium, a collection of tiny structures which explore the soil and absorb water and nutrients, which are then translocated back to the plant. The fungus produces specialized structures within the root, called arbuscules, where they exchange nutrients obtained from the soil with the plant.

Integrating biologicals into your current agricultural practices

Biologicals like symbiotic microorganisms can complement conventional products on your farm. Here are some of the benefits they can provide as part of an integrated agricultural system:

  • Enhanced nutrient efficiency: Improves plant’s ability to absorb nutrients.
  • Improved soil structure: Fungal networks help stabilize soil and retain moisture.
  • Increased crop resilience: Plants become more tolerant to drought, salinity, and disease.
  • Sustainable productivity: Maintain or improve yields while preserving soil health.

Not all microorganisms are the same

Different strains of mycorrhizal fungi vary in effectiveness. For example, Glomus iranicum is a type of fungus known for its ability to grow in intensive systems and significantly improve root development and nutrient absorption.

By integrating biologicals with existing agricultural practices, farmers can build more resilient, productive, and sustainable systems. Symbiotic microorganisms are not a silver bullet — but they are a powerful tool in the modern grower’s toolkit.
