Charles Kellogg quotes:

Essentially, all life depends upon the soil ... There can be no life without soil and no soil without life; they have evolved together.

As a farmer, man himself became closely attached to the landscape, firmly rooted to the soil that supported him. At times the soil seemed bountiful and kindly and again stubborn and unfriendly, but it was always a challenge to man's cunning.

Each soil has had its own history. Like a river, a mountain, a forest, or any natural thing, its present condition is due to the influences of many things and events of the past.

Civilization has its roots in the soil.

Essentially, all life depends upon the soil

Nature has endowed the earth with glorious wonders and vast resources that we may use for our own ends. Regardless of our tastes or our way of living, there are none that present more variations to tax our imagination than the soil, and certainly none so important to our ancestors, to ourselves, and to our children.
