Consider the following statements about alluvial soil present in West Bengal. 1. Old alluvium is more fertile than new. 2. In Jalpaiguri it is called Terai soil. 3. It loses fertility due to river bank erosion. Which of the following is true?

New alluvium soil is more fertile than old alluvium soil. Alluvial soil is not found in Jalpaiguri. Alluvial soil is found along the banks of the rivers. Hence, loses some of its fertility due to river bank erosion.
