Whether you call it dirt, earth or soil, the matter that covers the surface of the land is vital to us all.
Made up of a mixture of minerals, decaying organic material, air, water and living organisms, soil provides the foundation for life on the land. As one of Earth’s precious and finite resources, soil must be used wisely and managed well.
Soil quality underpins our wellbeing – it helps to meet our basic needs for food, it stores and filters water, it helps to mitigate flooding and climate change, and it traps pollutants. Aotearoa New Zealand’s economy has a large stake in soil health - our soil-dependent primary industries create over 70% of the country’s export earnings and are major employers. It also supports recreation, from sports to gardening. The stamp issue for June focuses on the importance of soil for people and planet.
