78 soil families.
Soils occurring in different landforms are studied in respect of their morphology, physical and chemical characteristics. In accordance with the physiographic sequence of the terrain features, 78 soil families were identified in Sikkim State and mapped into 69 mapping units.

What are mountain soils?
Mountain soils are generally defined as poorly developed, skeletal, shallow, acidic and relatively infertile. They are also highly diverse and can vary significantly within limited areas due to different exposure and steepness. In general, they become less fertile and less developed as elevation increases.

alluvial soils
Soil Type:

Which soil is found in Arunachal Pradesh?

What is yellow soil?
a soil formed under broad-leaved forests in humid subtropical regions, chiefly on parent material fromclayey shales. It has an acid reaction and low humus content, and its yellow color is caused by the presence of ferric hydroxide.
Why soil is red?
The iron and manganese particles have been leached out due to high amounts of rainfall or drainage. This colour indicates good drainage. Iron found within the soil is oxidised more readily due to the higher oxygen content. This causes the soil to develop a ‘rusty’ colour.
