Soils is the limited physical land resources which needs great care during cultivation otherwise the soils would be unproductive for growth and development of plants especially for growing of annual crops. These days the world population is increasing and estimated to be 7 billions but most of the arable lands are becoming non fertile due to erosion, salinity and sodicity, and mismanagement. In addition, the demand for food in the world is increasing. Thus, good understanding to the characterization of soils in terms of physical and hydraulic properties can contribute significant role in managing the limited resources i.e. soils. I strongly belief that this book is very important for those who need practical information in this area. It is therefore this book is important useful for agricultural managers, researchers, students and instructors.
