soil, n.All

Mars' soil is rust colored because it's full of rust

Earthworms are useful in that their secreted 'slime' contains nitrogen and also holds clusters of soil particles together in formations called aggregates

The tunneling of earthworms deeply in the soil brings subsoil closer to the surface, thereby mixing it with the topsoil

Soil is the basis of everything.

Chicago was raised by over a foot during the 1850s and ’60s without disrupting daily life.

Soil is a stuff to which man owes his very existence. Despite man's artistic pretensions, his sophistication, and his many accomplishments - owes his existence to a six-inch layer of topsoil and the fact that it rains.

Soil is the great connector of lives, the source and destination of all. It is the healer and restorer and resurrector, by which disease passes into health, age into youth, death into life. Without proper care for it we can have no community, because without proper care for it we can have no life.
