World Soil Day (WSD) is held annually on 5 December to focus attention on the importance of healthy soil for the sustainable management of soil resources. Our planet’s survival depends on the link with soil. Over 95 percent of our food comes from soils and 15 of the 18 naturally occurring chemical elements essential to plants.
The theme for the WSD celebration in 2024 is “Caring for Soils: Measure, Monitor, Manage.” This theme highlights the importance of accurate soil data and information in understanding soils characteristics and supporting informed decision-making on sustainable soil management for food security.
What is soil?
Soil is the thin layer of material covering the earth’s surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly. Most plants get their nutrients from the soil and they are the main source of food for humans, animals and birds. Therefore, most living things on land depend on soil for their existence.
Soil is a valuable resource that needs to be carefully managed as it is easily damaged, washed or blown away. If we understand soil and manage it properly, we will avoid destroying one of the essential building blocks of our environment and our food security.
