Paperback. Condición: New. Print on Demand. This book examines various theories on the creation of loess, a fertile soil found in the river valleys of Europe. The author presents multiple viewpoints on how loess was formed, including the theory that loess is a glacier deposit. While exploring the geographical distribution of loess, the author also discusses its geological age and chemical components. The book also explores the physical structure of loess and how it affects plant growth. Ultimately, the author concludes that loess is an important soil type that has been used for centuries to grow crops and support human populations.
