Soil Science is an important and basic science in agriculture which deals with different domains of soil research namely, soil formation, genesis and classification, soil physics, soil chemistry, soil fertility and plant nutrition, soil biology, etc. Characterization as well as our understanding of soils requires that they are precisely analysed and described. While the physical properties of soils determine their adaptability to cultivation, chemical properties tells about their chemical environment and nutrient status to the crop production - the most important use of soils on this densely populated planet. Determination of different soil physical and chemical properties in the field or in the laboratory following suitable analytical methods is first step towards appropriate soil managements and scientific recommendations for increasing crop production.
