Feeding the World: The Importance of Stewarding Soil Microorganisms
The 21st century features many advanced technologies—self-driving cars, drones, robots, etc.—but we are still facing one big challenge that technology may or may not be able to solve for us: How can we sustainably feed the world while maintaining a safe environment and preserving our natural resources?
In farming, it always begins with the soil. Good farmers farm crops, great farmers farm the soil. Important to having great soil is building an active and diverse microbiome that will structure the soil and move and process nutrients in ways most beneficial to plants. The more microbes there are in a soil (and the greater the diversity of those microbes), the more fertile that soil becomes. Thus, careful husbandry of the soil microbiome will successfully contribute to better yields to fight hunger while preserving Earth’s resources.
It’s hard to even conceptualize how much life is going on in the soil around a plant: in fact, a teaspoon of soil contains around 50 billion microbes. Microbes are the living engine of soil. These microbes perform many functions essential for helping plants reach their genetic potential, including:
Those benefits create an environment favorable for seed germination, transplant survival, and root growth. As a soil scientist, some of my top recommendations for stewarding the soil and its living microbiome include:
An entire world exists in just a handful of soil, and the tiny beings within it hold the key to successful crop production. As we steward our fields for sustainable crop production, we must make sure to consider the effect our practices are having on those essential microorganisms—the living engine of soil.
