A systematic study of the soil is the basic tool for determining the capabilities and limitations of land. Land judging is used to teach and promote a better understanding of soils through a study of the physical properties of the soil and to show how to use these properties in determining proper land use. Most of the characteristic. s that are used to identify soils can be determined in the field.
