Field Determinations
A guide to determining the various soil components on the basis of characteristics and
diagnostic procedures is given in Table 5.36, and a guide to the identification of the fine-
grained fractions is given in Table 5.37.
Field Descriptions
The elements of field descriptions, including the significance of color, and nomencla-
ture for structure and fabric, are given in Table 5.38. The importance of complete
field descriptions cannot be overstressed, since they provide the basic information for
evaluations.
