In order to live off a garden, you practically have to live in it. – Frank McKinney Hubbard

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 Simonson, USDA Yearbook of Agriculture, 1957
