Leonardo da Vinci remarked, “in order to be a successful farmer one must know the nature of the soil.” Even today in the age of hydroponics, most of our food, over 98 percent by some estimates, is grown from field on a soil medium. Beyond growing our food, the way we treat our soil determines the nature of our environment and the climate.
There is a great and still relatively undeveloped agronomic and environmental opportunity that could make an important global difference. This opportunity is hidden underneath our feet, in the living soil. The soil is home to the most populous community on the planet. Around the seven continents, the living soil is the Earth’s most valuable bio-system, providing ecosystem services worth trillions of dollars. The most limiting resource for global food system is drought, with over 75 percent of the crop insurance outlay related to these events.
