Kerala Soil Museum

The state government established the soil museum to provide an exhibition of the richness of Kerala's soils and mineral resources, as well as to foster public awareness about conservation and ecological protection.[5] The museum's staff were trained by personnel from the World Soil Museum at Wageningen University in the Netherlands.[4]

The most important exhibits in the museum are a set of 82 soil monoliths 1.5 metres tall which preserve and display the intact soil profiles of all of the 82 soil series recognised in the state of Kerala.[2] Each monolith was dug from the ground without disturbing its elements and was processed for one month or longer before being mounted for museum display. Alongside each monolith is information about the soil, including the physical characteristics of the soil series, where it is found, its nutrient status, the crops it is best suited for, and recommendations for use and management of land where the soil is present.[2][4] The soil classifications displayed in the museum are based on the US Department of Agriculture soil taxonomy.[2]

Other exhibits include a geologic map of Kerala; a map of Kerala showing the distribution of the eight soil orders represented in the state; collections of rocks and minerals and the physical constituents of soil, such as clay, silt, sand, stone, and gravel; displays explaining how soils are formed; and displays about the relationship of soil to the issues of food security and climate change.[2]

Attached to the museum is a Soil Information Centre that exhibits a model of a watershed, illustrating both the elements of a watershed and a variety of conservation measures.[2]
