Quote for Thought
"Be it deep or shallow, red or black, sand or clay, the soil is the link between the rock core of the earth and the living things on its surface. It is the foothold for the plants we grow. Therein lies the main reason for our interest in soils." 
Roy W. Simonson, Director of Soil Classification and Correlation, Soil Conservation Service, "USDA Yearbook of Agriculture," 1957
