We often treat soil like it’s just dirt, but it’s so much more. It’s the source of life in many ways. Healthy soil is a living, breathing ecosystem that serves as our planet’s most vital capital. The health of soil, often termed “dynamic soil quality,” is a measure of its response to agricultural management and climate change. A single handful of healthy earth contains billions of microbes that work in permanent, silent partnership with plants to cycle nutrients, filter water and capture carbon. For farmers, this living network drives yield and resilience; for the public, it secures our food supply and stabilizes our climate.
