Selected Trees and Shrubs Evaluated for Single-Row Windbreaks in the Central Great Plains (Classic Reprint)


Book Description

Excerpt from Selected Trees and Shrubs Evaluated for Single-Row Windbreaks in the Central Great Plains States Forestry Project immediately after the Dust Bowl Days of the 1980's were 10 rows wide. About 50 percent were 5 to 7 rows wide and the remaining 10 percent were either 3, 4, 11, or 21 rows wide Such wide barriers are effective but they waste valuable cropland. Ideally, a single row of trees or shrubs that attain substantial and uniform height in a short time, retain branches to the ground and provide sufficient year-round density would use the least land and be most desirable.

Soil Erosion Research Methods


Book Description

This new edition of Soil Erosion Research Methods retains the themes and layout of the first edition. However, most chapters have been revised and some additional chapters have been added. There are new chapters on modeling wind and water erosion. Extensive revisions and updating have been done in chapters dealing with assessment of erosivity and erodibility, erosion, crop productivity, measuring sediment yield from river basins and field plot techniques. There is extensive updating of current statistics on the global magnitude of soil erosion by water and wind and on denudation rates. Several new authors have made significant improvements in revising and updating available information.




Handbook of Processes and Modeling in the Soil-Plant System


Book Description

Learn to create and use simulation models—the most reliable and cost-effective tools for predicting real-world results! The Handbook of Processes and Modeling in the Soil-Plant System is the first book to present a holistic view of the processes within the soil-plant-atmosphere continuum. Unlike other publications, which tend to be more specialized, this book covers nearly all of the processes in the soil-plant system, including the fundamental processes of soil formation, degradation, and the dynamics of water and matter. It also illustrates how simulation modeling can be used to understand and forecast multiple interactions among various processes and predict their environmental impact. This unique volume assembles information that until now was scattered among journals, bulletins, reports, and symposia proceedings to present models that simulate almost all of the processes occurring in the soil-plant system and explores the results that these models are capable of producing. With chapters authored by experts with years of research and teaching experience, the Handbook of Processes and Modeling in the Soil-Plant System examines: physical, chemical, and biological soil processes the soil formation and weathering process and its modeling the impact of radioactive fallout on the soil-plant system soil degradation processes and ways to control them water and matter dynamics in the soil-plant system growth and development of crops at various levels of production the potentials and limitations of using simulation models Students, educators, and professionals alike will find the Handbook of Processes and Modeling in the Soil-Plant System an invaluable reference on the soil-plant-atmosphere system and an ideal tool to help develop an effective decision support system.
