Once again, noted author Cris Peterson brings both wonder and clarity to the subject of agriculture, celebrating the cycle of growth, harvest, and renewal. Using the corn plant as an example, she takes the reader through the story of germination and growth of a small corn seed into a giant plant reaching high into the air, with roots extending over six feet into the ground. The book also discusses the makeup of soil and the amazing creatures who live there--from microscopic one-celled bacteria to moles, amoebas, and earthworms.
