The UN observance called World Soil Day takes place every 5 December. The event was first instituted in Thailand by former king Bhumibol Adulyadej, which is why its date is set on this monarch’s birthday.

World Soil Day differs significantly from Earth Day, despite the similarity of name. Earth Day celebrates Earth as a planet, while Soil Day celebrates soil in particular.
World Soil Day is meant to draw attention to the critical role of Earth’s many soil types and how they contribute to ecosystems, biodiversity of plants and the animal life those plants sustain, and to human agricultural endeavours.
The soils of our planet contain water and minerals that then enter into plants, and which from there enter into animals and people. Nutrition is thus a key area where soil is important. No wonder there are over 60,000 “soil scientists” in the world today!
Key emphases of World Soil Day include how to prevent excessive soil erosion and how to protect the ecosystems that soils sustain.
