When is World Soil Day 2026?

World Soil Day is December 5 every year, a Saturday in 2026. The United Nations General Assembly made it an official day in 2013, and the first one was held on December 5, 2014.

What is soil made of?

Soil is a mix of tiny bits of rock, water, air and humus, the dark material left when plants and animals break down. The What Is Soil? fact file and the soil layers pages explain it for young children.

Why are earthworms good for soil?

Earthworms dig tunnels that let air and water into the soil, and they eat dead leaves and leave behind castings that feed plants. The Earthworms Help the Soil poster and the Wiggly Worm fact cards cover it for K to 2nd grade.

What soil experiments can a class do?

The Soil Shake Jar shows how soil settles into layers, Compost in a Bag shows food scraps turning into soil, and the Soil Detective sheet has students look closely at a soil sample. The edible soil layers recipe has an allergy note.
