Limitations in Genetic Systems of Soil Classification:

The major defects in the genetic system of soil classification are as follows:

(i) The two highest categories are defined in genetic terms and not on the basis of properties of soils themselves.

(ii) The definitions and concepts of the highest category (order) in relation to soil properties are not clear.

(iii) The concepts and definitions of great soil groups have been outlined on the basis of only environmental factors and not on the basis of soil properties.

(iv) The classification of arable soils under this system becomes ambiguous because of variation under virigin and cultivated soil conditions.

(v) There are possibilities to attempt definition of units in the lower categories in relation to very few soil properties seemed to be important for one interpretation. Where this was done, it was impossible to utilize those results for other interpretations.

(vi) Most emphasis has been given on soil colour or vegetation than that of soil properties under this system for making nomenclature of the highest categories.

(vii) In this system, it was difficult to name intergrades as the nomenclature was evolved from various languages mixing with nouns and adjectives.
