constituents of variable thicknesses, which differ from the parent materials in their morphological
, physical, chemical, and mineralogical characteristics. Strictly speaking, soil is the depth of regolith that influence and have been influenced by plant roots.

“I saw all the people hustling early in the morning to go into the factories and the stores and the office buildings, to do their job, to get their check.

“History is largely a record of human struggle to wrest the land from nature, because man relies for sustenance on the products of the soil. So direct is the relationship between soil erosion, the productivity of the land, and the prosperity of people, that the history of mankind, to a considerable degree at least, may be interpreted in terms of the soil and what has happened to it as the result of human use.” ~ Hugh H. Bennett and W.C. Lowdermilk, circa 1930s
“... if this is to be a permanent nation we must save this most indispensable of all our God-given assets -- the soil, from which comes our food and raiment. If we fail in this, remember that much sooner than we have expected this will be a nation of subsoil farmers.” ~ Hugh H. Bennett (1933)
“Soil erosion is as old as agriculture. It began when the first heavy rain struck the first furrow turned by a crude implement of tillage in the hands or prehistoric man. It has been going on ever since, wherever man's culture of the earth has bared the soil to rain and wind.” ~ Hugh H. Bennett and W.C. Lowdermilk, circa 1930s
“The plain truth is that Americans, as a people, have never learned to love the land and to regard it as an enduring resource.” ~ Soil Conservation by Hugh H. Bennett
“The soil is the great connector of our lives, the source and destination of all.” ~ The Unsettling of America (1977) by Wendell Berry
