Study to identify frost-susceptible soils. By using variables of bulk density, sand content and calcium, equation was constructed which accounted for 83% of total variation in heaving.
This extensively illustrated volume is a definitive sourcebook on the utilization of arid lands. It offers a wealth of current knowledge about the nature and distributiion of the soils of Arizona and their relation to the diversity of geology, climate, vegetation, and fauna of the state.
This book provides an overview of the distribution, properties, and function of soils in the U.S., including Alaska, Hawaii, and its Caribbean territories. It discusses the history of soil surveys and pedological research in the U.S., and offers general descriptions of the country’s climate, geology and geomorphology. For each Land Resource Region (LRR) – a geographic/ecological region of the country characterized by its own climate, geology, landscapes, soils, and agricultural practices – there is a chapter with details of the climate, geology, geomorphology, pre-settlement and current vegetation, and land use, as well as the distribution and properties of major soils including their genesis, classification, and management challenges. The final chapters address topics such as soils and humans, and the future challenges for soil science and soil surveys in the U.S. Maps of soil distribution, pedon descriptions, profile images, and tables of properties are included throughout the text.

In these books, we bring together and correlate recent information known to have a prominent influence on the rate of movement of pollutants from wastes and their leachates in the soil. The emphasis is on those characteristics most amenable to modification and their management, such that secure and rational choices of disposal can be made. Identification of limits of the state of the art are carefully defined. This book presents five distinct but related subject matter sections. The first topic relates to soil as a natural system to prepare the reader with a basic knowledge of soil properties as they must become involved in waste management at the disposal facility. The soil, its depth-profile, and certain characteristics are identified and described.
Soils of arid regions
This work features scientific, technical and practical information on mineral, organic and synthetic conditioners, as well as their beneficial effects on the soil's physical properties that promote optimal plant growth, maximize soil fertility, and enhance biomediation processes. It promotes the synergistic use of various agricultural technologies to manage global concerns of decreasing arable land.
