Our World, Our Soil

Our world rests upon soils. They blanket the Earth’s continents with complex mixtures of minerals, air, water, decaying remains of life, and countless living organisms.

Soils make our lives possible. Everything we do is touched directly by soils or indirectly by the work of soils in natural ecosystems.

The secrets of soils are the secrets of our lives.
