Kerala Soil Museum

The Kerala Soil Museum is housed at the Central Soil Analytical Laboratory at Parottukonam, in Thiruvananthapuram district. The state's Department of Soil Survey and Conservation created it to show the range of Kerala's soils and minerals and to promote conservation, and it opened on 1 January 2014. Its staff received training from the World Soil Museum at Wageningen in the Netherlands, and it has been called the largest soil museum in the world.

At its heart are 82 upright cases, each 1.5 metres tall, holding an undisturbed profile of every soil series recognised in Kerala. Each block was dug out intact and treated for a month or longer before mounting, with notes beside it on its character, where it occurs, its nutrients and the crops it suits. Other displays cover the state's geology and eight soil orders, rocks and minerals, how soils form, and soil's role in food security and climate change, and an attached centre has a watershed model.
