Did you know that soils support more life beneath their surface than exists above? Soil is a living, dynamic resource at the surface of the earth. It is a complex habitat of mineral and organic particles; living organisms including plant roots, microbes, and larger animals; and pores filled with air or water. In a thimble full of soil—about a gram in weight—you can expect to find 100 million to 1 billion bacteria!
