Which of the following statements with reference to soil forming processes is/are correct? 1. Translocation, enrichment, removal and transformation are different classes of soil forming processes 2. In translocation, fine particles are transported downward by eluviation and accumulate in lower horizons by illuviation Select the answer using the code given below:
Options
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Correct answer
C. Both 1 and 2
Step-by-step solution
Soil forming processes are broadly grouped into four classes: additions (enrichment), losses (removal), translocations, and transformations. Thus, the first statement is correct. Translocation involves the movement of soil-forming materials through the developing soil profile. This occurs primarily by water moving through the soil, transferring materials from upper to lower portions. The removal of material from the upper horizon is called eluviation, and its deposition in the lower horizon is called illuviation. T
