The soil type is the second most dominant type in the region covering 33.06 percent of the land area.

The soil of Tripura is faced with the problem of rapid soil erosion. This occurs due to chemical weathering with the high annual rainfall. Another factor that is responsible for the rapid erosion of soil in Tripura is the withdrawal of vegetation in the state which has caused the high velocity of the wind to remove the soil cover.
