Soil day corresponds with the birthday of Bhumibol Adulyadej, King of Thailand. This date was proposed by FAO to honour him for his efforts in the promotion of soil science and soil resources conservation and sustainable management.

In an increasing number of countries across the world this day is celebrated each year with a wide ranging of activities and festivities. World Soil Day celebrates the importance of soil as a critical component of the natural system and as a vital contributor to the human commonwealth through its contribution to food, water and energy security and as a mitigator of biodiversity loss and climate change. It is celebrated particularly by the global community of 60 000 soil scientists charged with responsibility of generating and communicating soil knowledge for the common good (IUSS).
