For the scientific management of natural soil and water resources, to achieve high use efficiency of applied inputs, a systematic study of soil land slopes characteristics and management of calcareous soils were studied in JAU, Junagadh Gujarat (India). Physical and hydrological characteristics of land slopes, soil classification, evaluation and management of soil sustainability, water resource and climate constraints and soil-site suitability of important crops in different land slopes of calcareous black soils are discussed at length in the text. The book will meet to growing need of all U.G and P.G students, teachers as well as scientists of Agricultural Chemistry and Soil science, Agril. Physics, Soil Physics, Soil and Water Management Engineering, Water Management, Agronomy, Civil Engineering and Environment Science of different Agricultural Universities of any nations, NGOs and Organizations at World level. This book will be also useful in the field of Soil Mechanics, Civil Engineering, Canal Design and Dams etc.
