Focus Soil: Precious dirt at our feet
What do you think of when you hear the word soil? Do you smell the moist, slightly musty soil of the forest? Do you feel the dried earth in your hands from your gardening? Do you multiply land prices by square meters in your head?
From an environmental perspective, soil is the foundation of life. It has been formed over thousands of years from bedrock through the interaction of climate and organisms, primarily countless fungi, bacteria and plants. It holds back rainwater, stores nutrients, is the habitat for thousands of creatures and serves as a carbon sink. However, if new housing and roads are built, if pollutants penetrate into the ground, or if heavy machinery damages the soil, it loses the ability to perform these functions in the ecosystem. It takes decades or even centuries for damaged soil to become fertile again – in terms of human life, soil as a natural resource is not renewable.
- SOIL – PRECIOUS DIRT AT OUR FEET
A lot of strain is being placed on our soils. What are researchers doing to ensure that the most important basis for life is preserved?
- BOG SOILS
Changes in raised bogs in Switzerland reveal how bogs in the far north might be modified by climate change.

The lab-microtome is a proprietary development of the WSL. It helps to prepare thin section slides for
microscopic analysis of wood samples.
Soil - Precious dirt at your feet
WSL has a long tradition in looking at the properties of soils and the processes that occur below ground. Researchers have made great advances in recent years, especially in the field of microbial ecology.
