Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

"The use of liming materials on acid soils to supply available calcium and correct soil acidity long has been regarded as a basic principle in the Iowa system of soil management. The beneficial effects are associated primarily with the efficient production of legumes in various cropping systems, thereby contributing to the maintenance of soil fertility and conservation of soil resources. Many of the important agricultural soils in Iowa were originally well supplied with lime, but through leaching, erosion, decomposition processes, removal by crops and the sale of livestock products there has been a gradual tendency for them to become acid" -- p. [471]

Sometimes called “black gold,” Iowa’s deep, rich soils are a treasure that formed over thousands of years under the very best of the world’s grasslands—the tallgrass prairie. The soils are diverse and complex and hold within them a record not only of Iowa’s prehistoric past, but also of the changes that took place after settlers utterly transformed the land, as well as the ongoing adjustments taking place today due to climate change. In language that is scientifically sound but accessible to the layperson, Kathleen Woida explains how soils formed and have changed over centuries and millennia in the land between two rivers. Its soils are what make Iowa a premier agricultural state, both in terms of acres planted and bushels harvested. But in the last hundred years, large-scale intensive agriculture and urban development have severely degraded most of our soils. However, as Woida documents, some innovative Iowans are beginning to repair and regenerate their soils by treating them as the living ecosystem and vast carbon store that they are. To paraphrase Aldo Leopold, these new pioneers are beginning to see their soils as part of a community to which they and their descendants belong, rather than commodities belonging to them.
