Sandy soils cover approximately 900 million ha worldwide, and there are extensive areas of sandy soils under cultivation. Most sandy soils have high water permeability, low water-holding capacity, low ability to retain and exchange nutrients, weakly developed soil structure and they may be prone to erosion by wind. As irrigation is required for obtaining good crop yields, there is a risk of substantial leaching of nutrients and pesticides, and ground water depletion. Due to global pressure on land resources, marginal soils such as sandy soils are taken into production or cultivated more intensely. Sandy soils ¿ as a group of soils with specific characteristics and ecological limitations ¿ have received limited research attention. This books presents the main papers from the Global Conference on Sandy Soils which was held in June 2023 in Madison, USA. This book focuses on novel and exciting aspects of research on sandy soils which is presented into three sections: Distributionand Assessment, Soil Carbon and Soil Health, and Water and the Environment. It presents a global glimpse on what recent progress has been in the study of sandy soil and their properties and management.

This book provides an up-to-date and comprehensive report on the soils of Wisconsin, a state that offers a rich tapestry of soils. It discusses the relevant soil forming factors and soil processes in detail and subsequently reviews the main soil regions and dominant soil orders, including paleosols and endemic and endangered soils.
