Beneath the verdant tapestry of Iowa lie a treasure trove of diverse and remarkable soils—a testament to the state's rich agricultural heritage. From the fertile plains of the Missouri River Valley to the rolling hills of the Loess Hills, Iowa's soils have played a pivotal role in shaping the state's identity as the "Breadbasket of the Nation."

In Iowa Remarkable Soils, renowned soil scientist Dr. Richard Arnold embarks on a captivating journey through the state's soil types, delving into their history, characteristics, and the crucial role they have played in Iowa's agricultural success.

A Tapestry of Soil Types

Iowa's soils are as varied as the state's landscape. From the deep, rich Mollisols of the western plains to the sandy Alfisols of the eastern counties, each soil type possesses unique properties that have shaped Iowa's agricultural practices.

Mollisols: These deep, fertile soils are the backbone of Iowa's agricultural production. They are characterized by their dark, organic-rich surface horizon and their ability to hold water and nutrients, making them ideal for growing corn, soybeans, and other crops.
Alfisols: These soils are found in the eastern part of the state and are characterized by their lighter color and lower organic matter content. They are suitable for a variety of crops, including corn, soybeans, and small grains.
Inceptisols: These soils are young and have not developed distinct soil horizons. They are found in areas with steep slopes or recent erosion and are often used for grazing or forestry.
Entisols: These soils are very young and have little to no soil development. They are found in areas with recent deposition, such as floodplains or sand dunes.

History and Formation

The soils of Iowa have evolved over thousands of years, influenced by climate, vegetation, and geological processes. During the Ice Age, glaciers covered Iowa, leaving behind a thick layer of glacial till. This till became the parent material for many of Iowa's soils.

As the glaciers receded, wind and water carried away some of the finer particles, creating the rolling hills and valleys that characterize Iowa's landscape. The remaining sediments were shaped by the action of plants and animals, and over time, distinct soil profiles developed.

Agriculture and Soil Conservation

Iowa's fertile soils have been the foundation of the state's agricultural success. However, these soils are also vulnerable to erosion and degradation. Iowa farmers have adopted a variety of soil conservation practices to protect their valuable resource, including:

Contour plowing: This technique involves plowing the land along the contours of the landscape, which helps to reduce erosion.
Strip cropping: This involves alternating strips of different crops, which helps to break up the force of wind and water erosion.
Terracing: This is a method of creating level terraces on sloping land, which reduces erosion and improves water retention.
No-till farming: This is a relatively new technique that leaves crop residues on the field after harvest, which helps to protect the soil from erosion and improve soil health.

Iowa Remarkable Soils is a comprehensive and engaging exploration of the state's diverse and vital soils. Through its vivid descriptions, stunning photography, and insightful scientific analysis, Dr. Arnold's book provides a deep appreciation for the incredible legacy of Iowa's soils and the importance of their conservation for future generations.

Whether you are a farmer, a land steward, or simply someone who is curious about the natural world, Iowa Remarkable Soils is an essential read that will deepen your understanding of this remarkable resource.
