Explanation:

Explanation: Peaty soils are locally called Kari in Kottayam and Alleppey districts of Kerala.
Formation: These are marshy soils and are a result of water logging and anaerobic conditions (which leads to partial decomposition of organic matter).
Areas: They are found in the areas of heavy rainfall and high humidity, where there is a good growth of vegetation. It occurs widely in the northern part of Bihar, the southern part of Uttaranchal and the coastal areas of West Bengal, Orissa and Tamil Nadu.
Soil Colour and Texture: These soils are normally heavy and black in colour
Other characteristic features: These soils are characterised by a rich humus and organic content.There is a presence of iron and varying amounts of organic matter (10-40%). The organic matter in these soils may go even up to 40-50 per cent. These soils are generally acidic in nature. But at many places, they are alkaline also.
